EU Shark Fin Ban: proposal to land whole sharks could put a squeeze on shark fisheries

Making the rounds of many of the news outlets today is some good news offered by the European Union. Earlier this month, meeting in Brussels, the European Commission, siding with the opinions of 27 member nation fishery ministers, proposed amending EU regulations on shark fishing by recommending a total ban on shark finning both within EU waters and by all EU-registered vessels worldwide. Today, the Council of the European Union gave its approval of the measure.

While EU regulations have already prohibited shark finning, the actual execution was riddled with loopholes and special permits, all originally intended to promote commercial shark fishing management. However, monitoring and enforcement was difficult to attain and so, ultimately, a complete ban was deemed best.

As good as this all sounds, in reality it is an incremental step. Properly permitted vessels will still be able to take sharks, but they will be required to land them whole - fins attached. This is a disadvantage to the boat operators as whole shark carcasses will fill up a boat's hold with low value meat compared to the more highly prized shark fin. It could very well prove to be enough of an inducement for many boats to move out of the shark fin business altogether, finding it no longer economically worthwhile.

The proposed ban represents both a move by the EU to better monitor the shark fishing industry and to put the squeeze on what is viewed as an industry that would eventually collapse due to declining shark populations. While Asia is often criticized for its growing market demand for shark fin, it is the EU that happens to be the largest exporter of shark fins worldwide. As an example, according to some reports, the hammerhead shark has all but become extinct in the Mediterranean.

The EU fishery ministers are also seeking support for a measure that would ban the practice of discarding fish that do not meet qualifications or are commercially undesirable. What they are proposing is a major assault on bycatch. In essence, if you caught it, you keep it. And it could ultimately force fishing vessels to either utilize any and all approaches that would minimize bycatch (better fishing techniques, nets or hooks) or seek markets for catches that may not be as profitable. As reported by the Associated Press, the European Commission says that up to half of the whitefish and 70 percent of the flatfish caught by fisheries is discarded.

This proposal faces some stiff resistance from several member nations, particularly France and Spain, so time will tell as to whether it succeeds, But for now, the shark fin ban seems to be on track. The proposal awaits a first reading in the European Parliament before being formalized into law.

A positive step in a comprehensive, but complicated, strategy for shark conservation - addressing the dealers of shark fin products by simplifying shark fishery management policy and, in so doing, indirectly hitting them where it hurts most: the bottom line.

Philippine's Irrawaddy Dolphin: endangered but with a potential future thanks to local fishermen

In the Philippines, the Malampaya Sound is known for its ecological diversity, ranging from coral reefs to sea grasses to mangroves and lowland forests. It is also home to one of the most endangered species of dolphin: the Irrawaddy dolphin. The number of dolphin in the sound has dropped from 79 in 2001 to 42 and scientists believe that if the number dips below 40, the Irrawaddy dolphin population in the sound will collapse.

The Irrawaddy dolphin is a rather cute looking creature; a bit like a small beluga whale with a similar head shape and light grey in color. There are only about 6,000 Irrawaddy dolphins worldwide and it has been listed as "critically endangered" by the IUCN. Because of the Malampaya Sound's biodiversity, commercial and local fisherman have been attracted to the area and the sound is showing the impact of overfishing. No more so than with the plight of the Irrawaddy dolphin which is not commercially sought after but does become ensnared in the longline nets and, being then unable to reach the surface, drowns.

However, there could very well be a positive future for the Irrawaddy dolphin if the indigenous Tagbanua people have anything to say about it. Representatives of the World Wildlife Fund (WWF) who have been monitoring the situation and working with local Philippine officials, say that the Tagbanua tribe have both a cultural history that supports protecting the dolphin and employ fishing techniques that could allow the Irrawaddy dolphin's numbers to return.

“For them [the Tagbauna people], the dolphins are bearer of good tidings and are also the omen of something bad that will happen like typhoons or calamities, depending on the behavior of the animal,” said Mavic Matillano, who lead a study five years ago on the Irrawaddy dolphin. “That, in a way made the lumad [non-Muslim indigenous peoples in Mindanao] also believe that when you hurt a dolphin, something bad may happen to you.”

The cultural position forms the background for their approach to fishing. The Tagbanua fishermen use specific moon and tide schedules and selective harvesting, regardless of market demands, to avoid overfishing and wasted bycatch (which is the category in which the Irrawaddy dolphin finds itself).

According to the Philippine's Inquirer News, "WWF officials said the most important thing to do right now was to change the fishing practices of the coastal communities there. The group and [WWF author Raoul] Cola pointed to the Tagbanua fishing practices as a model of sustainable practice."

“Based on the principle of the interconnection, not only of ecosystems but also of the natural, social and spiritual worlds, these strategies demonstrate that the world view of the users molds their environment and defines the prospect of its sustainability,” said Cola.

The WWF is working with several Philippine agencies to implement commercial fishery management strategies based on the techniques employed by the Tagbanuas. The WWF is working hard to address funding issues, but they are encouraged by that fact that an indigenous Philippine tribe can serve as a model for many local coastal areas, rather than some outside group of "foreigners" imposing their beliefs on local fishermen.

The Irrawaddy dolphin, like other dolphins, is an important apex predator and vital to maintaining a healthy biodiversity in the Malampaya Sound. Let's hope that local wisdom and responsible fishing techniques can spread to ensure the dolphin's future.

Africa's Elephants and Water: African governments' dilemma in conserving both

In decades past, Africa was the wild continent, the epitome of nature unleashed. But in recent years it has been seen as a source of human sorrow through wars, drought, and disease. Two recent news articles confronted those images and show the dilemma that African governments currently face.

USA Today reported that poachers are taking a heavy toll on African elephants in supposedly protected reserves like Bouba N'Djida National Park in the Republic of Cameroon. Park rangers are poorly trained and ill equipped to combat the heavily armed poachers that have killed at least half of the park's 400 elephants for their ivory tusks. Northern Cameroon's elephant population represents 80 percent of the total population of savanna elephants in all of Central Africa.

Under pressure from the World Wildlife Fund and the European Union, the government sent in 150 soldiers at the start of the month and while there have been unconfirmed reports of confrontations, the poaching continues. Twenty elephants were reported killed in the first week of March alone.

The demand for ivory is a result of Chinese middlemen that have moved in to corner the market on poached ivory to satisfy a market demand for ivory in China.

USA Today reported, "Growing demand for ivory in China is 'the leading driver behind the illegal trade in ivory today,' said Tom Milliken, an elephant and rhino expert for the wildlife trade monitoring network TRAFFIC. China has a legal ivory market that is supposed to be highly controlled but tons and tons of illegal ivory has made its way there in recent years, said the Zimbabwe-based Milliken, who spoke in a conference call with several World Wildlife Fund officers."

In the meantime, according to an article in allAfrica, much of Africa is wrestling with the challenge of a lack of a predictable water supply. Africa can experience extremes in rainfall from torrential monsoons to severe droughts. Many African nations do not have the infrastructures to capture some of its rainfall so as to provide the people with a more dependable water supply.

Dams and reservoirs are a starting point but these are major construction projects which require the assistance of other nations to help design and build or, at the very least, fund. Part of the problem has been in finding a balance between environmental concerns over what these systems - which would provide need water storage and hydroelectric power - would do to the surrounding countryside versus the needs of the African people.

According to Mike Muller, professor at the Graduate School of Public and Development Management at the South African University of Witwatersrand, "You have a situation in Germany or Switzerland where you have strong environmental lobbyists who feel that dams are an infringement on the natural environment ... And you have situations where ministers will say, 'We cannot talk about storing water because that involves construction, which we cannot support'. Yet African governments know that if they don't store water given our variable climate, we are at the mercy of nature and it's a very cruel nature at times."

"The potential in the Congo could power all of Africa's current electricity needs and the same again, spare," says Muller. "If we start looking at the rest of southern Africa we could probably have replaced two of the huge coal-fired power stations that we're building in South Africa with hydropower, but the environmentalists don't want it, it's really anomalous."

Africa does appear to have one potential partner willing to participate: China. With its ongoing growth, China has an interest in Africa's natural resources and it has the skill and capabilities in building the dam and hydroelectric infrastructure that Africa needs.

"There is a coherence between China's capability as the world's pre-eminent builder of large water infrastructure and its interests in Africa's natural resources, many of which require the development of power, transport and water infrastructure for their successful extraction," says Muller.

So, here is the socio-political dilemma: China could be Africa's shining white knight coming to its aid to provide the necessary infrastructure to better ensure a constant water supply. In turn, China also becomes a strong economic partner. With that relationship in place, what are the chances that African governments that are benefiting from trade with China will be willing to seriously curtail the illegal ivory trade since most of the ivory is going to their new economic ally?

Many western nations want to see Africa preserve its wildlife heritage, but we have also seen the terrible price paid in human suffering when African nations are struck by drought and the famine it can produce. Will China be willing to curtail its demand for ivory as a trade-off for gaining other natural resources that Africa has to offer its industrious neighbor to the east? Will western nations step up and offer solutions for Africa that can meet the challenges of both preserving the environment - including iconic animals like the elephant - and providing a desperately needed consistent water supply for its people?

Where some nations wrestle with ecology versus energy demands in the form of coal and oil, Africa is having to consider something more fundamental: the need for water to survive.

Titanic Centennial: a testament to man against nature

As midnight approaches this Wednesday, 100 years ago the luxury ocean liner, Titanic, had an unexpected encounter with nature that would seal the great ship’s fate in less than three hours. A glancing blow along an iceberg off the coast of Newfoundland started a sequence of events that led to one of the greatest maritime tragedies of all time.

Most of us know the particulars – we’ve read the stories, seen the long parade of television programs, and watched the movies, particularly James Cameron’s blockbuster film of the same name. With all tragedies there are questions to be resolved and the Titanic surely had its fair share of riddles and mysteries, many of which have been solved but some still persist to this day.

There have been several Titanic-related news items that have appeared recently, timed I’m sure with the upcoming centennial. One has to do with questions regarding the Titanic’s captain’s seemingly casual response to reports of approaching icebergs. Captain Edward Smith was the most experienced captain in the White Star Line and many have wondered why he never took the reports more seriously and initiated corrective measures. One rumor was that he was under pressure to remain under full speed, a directive coming from J. Bruce Ismay, head of the White Star Line and a passenger on the fateful voyage. But Capt. Smith was a master of transatlantic crossings and knew the risks involved.

Now, research that will appear in the April issue of Sky & Telescope presents astronomical evidence to show that possibly Capt. Smith was acting in accordance with his past experience with the occasional iceberg but could not have foreseen the ice that was moving into the normal shipping lanes because of an unusual occurrence that took place four months before. According to a team of forensic astronomers from Texas State University, a very rare and close juxtaposition of the sun and the moon to the earth in January of 1912 produced exceptionally high tides that could have dislodged icebergs normally originating in Greenland but which get stuck in shallower waters off of Newfoundland.

“The lunar connection may explain how an unusually large number of icebergs got into the path of the Titanic,” said David Olson, Texas State University physicist, one of the leaders of the research.

Long before I was a diver, long before the magnitude of the Titanic disaster really meant anything to me, this ship fascinated me. As a boy, I read my parent’s copy of A Night to Remember by Walter Lord over and over. And when I was older, particularly around the time that Dr. Bob Ballard found the Titanic’s final resting place, my fascination grew and I collected books and videos on the subject. In fact, during one boring stretch of recuperation from some surgery, I whiled away the hours building a model of the Titanic – before and after – using two model kits, one of which I fabricated into the wreck using many of my books’ photographs and drawings as a guide.

And like many scuba divers, I find diving on wrecks to be an otherworldly experience. There is something intriguing when you come upon a wreck. It seems so out of place; it’s not supposed to be here, it should be gliding across the surface above. And yet, here it is, slowly being consumed by nature. Wrecks can become beautiful artificial reefs, providing a wide variety of sealife with a new and unexpected home. They can also be a hazard for divers who penetrate the hulls if they drop their guard for even just a moment. And as we have all seen with ships like the Exxon Valdez, they can be deadly to marine ecosystems.

In the grander scheme of things, like Titanic, wrecks also serve as reminders as to the limits of our mastery of the natural world. When Titanic slipped beneath the surface of the icy North Atlantic with a rush of escaping air and the groans of twisting metal, taking over 1,500 lives with it, it became a tragic symbol of industrial and technological arrogance and of an upper class/lower class society at the time whose have and have-nots ultimately meant nothing in those freezing waters.

One hundred years later, Titanic rests in two main pieces with debris strewn across a wide area (recent pictures from RMS Titanic Inc, the salvage owners, have been assembled into a startling mosaic of where the ship lies today). With its iron being consumed by microorganisms and bacteria, it won’t be much longer before the once majestic profile will collapse into rubble.

But what Titanic represented back then - the pride, the achievement and the hubris and folly – is that still with us today? This great ship is a constant reminder that without acknowledging nature, we are masters of nothing. Nature provided the raw materials to build the Titanic, and it would seem that when mankind was at its industrial and technological zenith in self-serving luxury, nature reared up and acted swiftly to remind us who is truly the master of our domain. And since that cataclysmic moment, it has slowly been taking those resources back.

A lesson to be learned – again and again? A warning once more gone unheeded? Will our fate be, ultimately, not that different from that of the great ocean liner that passed into maritime history 100 years ago tonight?

BLUE: combining great ocean films with conservation

In the summer of 2009, the BLUE Ocean Film Festival held its inaugural event in Savannah, Georgia. Presenting both ocean-themed films and discussion panels covering a range of ocean conservation and filmmaking topics, it was very well received by an amazing mix of conservationists and media professionals. I was honored to moderate a discussion panel on shark conservation and it was at this event that I got to have my first extended conversations with people like Dr. Sylvia Earle, underwater photographer Brian Skerry, marine scientist Dr. Carl Safina, and many more. For a brief few days, I was in ocean advocacy heaven.

In 2010, a move was made to Monterey, California, and the event grew in scope to become BLUE - A Global Oceans Film & Conservation Event. Once again, great films from leading studios and filmmakers were presented and there were important discussion panels, and presentations. In fact, the biggest challenge was trying to be in more than one place at the same time - there was so much going on. Once again, I was honored to chair the discussion panel on shark conservation and was able to have as panelists Peter Knights, executive director of WildAid; Dr. Greg Stone, senior scientist for the oceans at Conservation International, Stefanie Brendl of Hawaiian Shark Encounters; and Laleh Mohajerani, executive director of Iemanya Oceanica. Additionally, I conducted an underwater video workshop which included some remarkable dives in Monterey Bay as the bay was experiencing a massive invasion of Sea Nettle sea jellies that summer.

The executive board of the festival decided to make the festival a bi-annual event and with that extra time to plan an even bigger and better event, BLUE returns to Monterey in 2012, scheduled for September 24-30. Between events, the festival crew has been busy with the BLUE on Tour, a traveling, educational ocean media show that has played to universities and communities from Mexico to Australia.

If you are an experienced underwater filmmaker, I encourage you to submit your films to the festival. There are a wide range of categories for pros and aspiring greats, ranging from theatrical to online shorts and you can submit through the festival's website or through Withoutabox.com, the online service that has come to dominate the film festival submission circuit. The regular deadline for submissions is March 16th but they have an extended deadline, so there's still time.

If you are an avid ocean lover, this is simply an amazing opportunity to not only learn about what is going on in the world of ocean conservation, science, and policy management, but it is also a chance to meet many notable names in a relaxed casual environment as there are social events in the evening that bring all the participants together in both a common cause. . . and a little wine and cheese.
BLUE - A Global Oceans Film & Conservation Event - September 24-30, 2012 in Monterey, California. Passes go on sale May 1st. Film submission's regular deadline is May 16th with an extended deadline to April 6th.

If you love the oceans, if you enjoy ocean films - then this is the place to be.

Catching Sharks On Camera: study of shark populations inside and outside protected areas

A press release from the Institute for Ocean Conservation Science has been making the rounds lately, explaining the Institute's research on reef shark populations within and outside of protected areas. Using techniques borrowed from researchers who study jungle cat populations, the ocean researchers used "chum cams" to attract and record sharks within two protected areas and two areas open for fishing. Their results add to the growing need for more marine protected areas.

'Chum cam' underwater video survey shows that reef sharks thrive in marine reserves

Study led by scientists from the Institute for Ocean Conservation Science at Stony Brook University uses video cameras to count reef sharks, showing that marine reserves benfit these top predators on the world's second largest barrier reef

STONY BROOK, NY -- A team of scientists, led by the Institute for Ocean Conservation Science at Stony Brook University, used video cameras to count Caribbean reef sharks (Carcharhinus perezi) inside and outside marine reserves on the Mesoamerican Barrier Reef in the Caribbean Sea. Using survey data collected from 200 baited remote underwater video (BRUV) cameras, nicknamed "chum cams," the scientists compared the relative abundance of these reef sharks in two marine reserves with those in two areas where fishing is allowed, and demonstrated that the sharks were more abundant in the reserves.

The research findings appear in the paper, "Reef sharks exhibit site-fidelity and higher relative abundance in marine reserves on the Mesoamerican Barrier Reef," published online today in the journal PLoS ONE. The purpose of the study, conducted from 2005 through 2010, was to test the hypothesis that carcharhinid shark species, which include requiem and whaler sharks, are more abundant inside no-take marine reserves where fishing for sharks and their prey is prohibited. The authors tested the hypothesis by using BRUV surveys to determine the reef sharks' numbers, and combined these results with acoustic monitoring to measure their site fidelity (remaining within the same local area) in Glover's Reef Marine Reserve, Caye Caulker Marine Reserve, and two reefs where fishing is allowed, all located in Belize.

"Although we know that relatively sedentary reef fish and lobsters benefit from marine reserves, this study now presents visual proof that large, active sharks are also dramatically more abundant inside these protected areas, too," said Mark Bond, lead author and doctoral student at Stony Brook University. "Nearly four times as many chum cam deployments in the marine reserves recorded reef sharks than on similar fished reefs. These areas provide the sharks and other coral reef species a respite from fishing, which means decreased fishing mortality for the sharks and more prey for them to eat."

The video cameras were enclosed in protective housing, and placed on the sea floor with small bait-filled cages positioned in front of them. Sharks, attracted by the smell of the bait, swam to the cameras, which allowed the research team to record, count, and compare shark populations in the marine reserves to those in the areas where fishing is permitted, at no stress to the sharks. In addition to the BRUV surveys, the scientists fitted 34 reef sharks with acoustic transmitters, and tracked their movements, using moored underwater listening stations. They found that the sharks, both juveniles and adults, live year-round within the reserves.

"Scientists who study tigers or jaguars in the wild use camera traps to count them," said Dr. Demian Chapman, assistant professor in the School of Marine & Atmospheric Science at Stony Brook, leader of the research team and assistant director of science of the Institute for Ocean Conservation Science. "It is just as difficult to count sharks in the ocean, so we took a page from the big cat researchers' playbook and deployed baited video cameras to count the sharks. It's only fitting since these large apex predators are the 'big cats' of the sea, and like their feline counterparts, their continued existence on Earth is threatened."

Due to intense fishing, Caribbean reef sharks are listed as "Near Threatened" by the International Union for the Conservation of Nature (IUCN) but it is possible they will be upgraded to "Vulnerable" by IUCN as more data are collected. They live in the western Atlantic Ocean, ranging from Bermuda to southern Brazil, and are the only Atlantic requiem shark species that undergoes its entire life cycles within coral reef ecosystems.

"Caribbean reef sharks and other shark species around the world are threatened by overfishing," said Dr. Ellen K. Pikitch, a professor in the Stony Brook University School of Marine and Atmospheric Sciences, who co-authored the paper and is executive director of the Institute for Ocean Conservation Science. "Our study demonstrates that marine reserves can help protect shark species that live on coral reefs. Moreover, the use of underwater video monitoring provides us with an excellent tool to determine if populations are recovering and thriving inside these reserves."

"As the saying goes, a picture is worth a thousand words," said Bond. "As Caribbean nations and other countries consider developing marine reserves, chum cams can virtually transport policy makers and the public beneath the waves and show them the benefits of these protected areas."

Oceanic Whitetip Sharks in Fiji: island cultures revere a threatened pelagic predator

The oceanic whitetip shark is a beautiful but feared shark. A feared shark because of its reputation gained during World War II for being attracted to the sounds of sinking ships and then, what with blood in the water, attacking sailors floating in the water. In Jaws, Quint's fictional monologue about the sinking of the Indianapolis was based on the real account of the ship's sinking. And, in truth, the oceanic whitetip was responsible for a number of sailor's deaths - along with battle injuries, starvation, and sea water poisoning taking its toll.

However, the fact is that the oceanic whitetip is a beautiful, pelagic or open-ocean shark and like many other shark species, its numbers have been in severe decline due to commercial fishing and bycatch. The IUCN has listed the species as vulnerable to extinction and its situation is not holding steady or improving by any means.

An article ran recently in the The Fiji Times Online in support of the oceanic whitetip. Fiji has several species of shark in relatively fair abundance in and about its reefs and the oceanic whitetip is one that will make an occasional appearance, approaching reefs on narrow continental shelves near deep water. Also, Fiji has a cultural history with several Fijian island peoples that revolve around sharks as mythical, even god-like, creatures. Several legends specifically involve oceanic whitetips and have them serving as protectors not predators.

The Fiji Times reported that Fijian "shark campaigner Manoa Rasigatale says the people of [the Fiji island of] Rukua, like elsewhere in Fiji where the shark is revered as a totem and protector, believe the oceanic whitetip and the rest of the species should be saved.

'Saving it is saving their tradition and their marine environment. It is as simple as that. Take away the shark and they lose their traditional tie to it and the story that has been passed on from one generation to another,' says Mr Rasigatale."

It's an interesting opposing juxtaposition to the Asian cultural history that defends the consumption of shark fin soup. Whose culture has a better right to predominate? One that promotes reverence of the shark or one that promotes its consumption?

Although Fiji has strict regulations regarding shark fishing, a movement is in the beginning stages with a shark sanctuary for the entire island chain as its ultimate goal. The Pew Environment Group and the Coral Reef Alliance (CORAL) are working with the Fijian government to make the sanctuary a reality.

Commendable as it may be, a shark sanctuary may not be enough to ultimately protect the oceanic whitetip as it is a long range nomad. That means considerable time spent outside of sanctuary boundaries, exposed to commercial fishing - whether deliberate or as accidental bycatch - in international waters.

The Fiji Times Online article is an interesting read both with regards to how the shark is entwined with the island's culture and identifying the specific fishing threats to the oceanic whitetip to which the island nation and supporting conservation groups are trying to address.

Going For The Deepest: submersibles prepare to return to the Marianas Trench

More than 50 years ago, two men reached the deepest point in the ocean: the Pacific Ocean's Marianas Trench at 35,800 feet. Crammed into a small sphere suspended underneath the large bathyscaphe Trieste, marine scientist Jacque Piccard and then Navy Lieutenant Don Walsh spent a short time on the bottom (according to Walsh, the bathyscaphe stirred up the bottom on its final approach and visibility was minimal, but some small sealife was detected). A feat accomplished, a record achieved.

And that was it.

Mankind has never returned to those extreme depths; instead, turning its attention skyward in a political race to the moon. A race that I was caught up in like many others and with few complaints; the spin-off technologies from the space program have brought us countless benefits. But there was an incredible amount of technology and potential knowledge left behind, waiting just below the waves.

As Richard Branson described it in 2011, "What if I were to tell you about a planet, inhabited by 'intelligent' beings that had, in the 21st century, physically explored zero percent of its deepest points and mapped only 3 percent of its oceans by unmanned craft, when 70 percent of that planet's surface was made up of water. Then I tried to convince you that only 10 percent of the life forms inhabiting that unknown world are known to those on the surface--you'd think I'd fallen asleep watching the latest sci-fi blockbuster. Then you discover that planet is Earth."

It seems, though, that things are about to change. A new race is shaping up and this time it is not motivated by political one-upsmanship but by a desire for mankind to turn its attention inward, to learn more about the oceans that cover the majority of this planet. In so doing, we may learn of new bounties for our benefit or may understand more about how the oceans function and what is happening due to our activities topside, from pollution to climate change.

While presidential candidates talk of bases on the moon, four organizations involved in the design and building of deep sea submersibles are looking downward, hoping to return once again to the Marinas Trench. And the first attempt in over a half century may take place in the next few weeks.

The four groups - Triton Submarines, DOER Marine, Virgin Oceanic, and film director James Cameron's Deepsea Challenge - have submersibles in various stages of design, construction or actual operation. But the two leading contenders at the moment are Richard Branson's Virgin Oceanic - working in conjunction with Hawkes Ocean Technologies - and Cameron's Deepsea Challenge, working in conjunction with the National Geographic.

All of these groups have the technological expertise to design submersibles that can withstand the extreme pressures of the Marianas Trench, a bone-crushing 15,750 psi, but what probably distinguishes the two leaders is the deep financial pockets at their disposal to make it a reality.

Based in Northern California, Graham Hawkes' Hawkes Ocean Technology produces a fascinating fleet of submersibles that look more like stubby-wing fighter jets. They are designed to fly through the water. I had a moment to speak with Hawkes at the 2010 BLUE Ocean Film Festival & Ocean Summit and, seeing that the design was quite different from your typical research submersible, I asked him what they were designed for. "For chasing after whales," he joked.



Hawkes had designed his Deep Flight Challenger to explore depths as deep as the Marianas Trench and was preparing to make the attempt with pilot Steve Fossett at the controls. Unfortunately, Fossett was killed in a small plane crash but a new pilot stepped in, Chris Welsh, along with the support of Richard Branson's Virgin Group. The overall plan for Virgin Oceanic is to send the Deep Flight Challenger on five of the deepest dives locations on the planet, which includes the Marinas Trench. The long-range goal is not just to reach the deepest point in the ocean - although that would undoubtedly bring the most attention - but to show that extreme deep sea exploration is viable. This is not a stunt; it is an attempt to show that man can and should be turning his attention to exploring the deep recesses of this planet as there is much to learn, and even gain materially, in the process.

James Cameron has melded technology and entertainment into many of his films (blockbusters like Titanic, Avatar, and the early Terminator films), but he has proven himself to be much more than an armchair science explorer and deep sea exploration became a particular area of serious interest and financial investment. Working with National Geographic (Cameron is an Explorer-in-Residence there) and Scripps Institution of Oceanography, among others, the Deepsea Challenger submersible was built and has already completed a five-mile dive to the New Britain Trench near the Solomon Islands.

The Deepsea Challenger is more utilitarian than elegant in appearance - a lime green cylinder, positioned vertically, with an array of lights midway and a spherical compartment at the lower end that has room for one pilot with a viewing window. Cameron intends to be the pilot, as he was on the recent deep dive, and though exact schedules are being kept under wraps, it has been said it might only be a matter of weeks before the Deepsea Challenger makes its attempt to return to the Marianas Trench.

"This quest was not driven by the need to set records, but by the same force that drives all science and exploration … curiosity. So little is known about these deep places that I knew I would see things no human has ever seen. Every dive teaches us more, and we are continuing to improve the sub and its systems daily, as we move through our sea trials,” says Cameron on the Deepsea Challenge website.

In the end, whoever gets there first, the Marianas Trench will once again be visited by terrestrial beings and, if it is to truly have any meaning and value, it must be seen in the context of exploring the vast oceans to better understand this crucial aquatic lifeblood that is key to the planet's survival. Whether it is finding new mineral resources, or new species, or better understanding the processes that make the oceans function - and therefore understanding how best to conserve and protect them - deep sea exploration is a pursuit that is within our reach and makes more sense in today's world.

We're not ready to pack up and move to another planet, so we best understand and protect the one we have now.

An Arachnid Winterland: Australia's wolf spiders escape flood waters

The picture above, taken by Daniel Munoz for Reuters, depicts a tranquil winter farmland scene - a blanket of white snow gently covering the ground. Ah, a classic winter tableau.

Or is it?

If it's winter, why is there no snow on the hillside behind the trees? And if you could get closer, you would see that it's not snow at all.

It's spider webs.

In Australia, following heavy rains and flooding in New South Wales, thousands of residents had to move to find drier ground. In the city of Wagga Wagga, over 8,000 residents needed to evacuate. Someone, or something, else also needed to evacuate: thousands upon thousands of wolf spiders.

Wolf spiders reside in tunnels or burrows in the ground. They line their homes with a silky web that facilitates easy and quick movements within the tunnel. With the flooding, the spiders moved to higher ground and as the soil remains saturated, returning to a damp home was out of the question. So the spiders built their webs above ground - their new homes spread out across the Australian farmland, looking for all the world like a fresh layer of snow. That is until you get up close and see all the wolf spiders wandering about over the webs, patiently waiting for the ground to dry out so they can return to their normally solitary, hidden lifestyle.

Creepy.

The many webs actually represent failed attempts at "ballooning." Ballooning is where a small spider releases a long silky strand of web which catches the wind and suddenly the spider is airborne. An effective means of travel - or, in this case, escape from a threatening situation - for small lightweight spiders, but many of the spiders here in Wagga Wagga were too heavy and so the threads would accumulate. The sticky threads would also latch onto the extra moisture in the air, making the webs more visible

However, while they wait for better living conditions, the spiders also perform an important service. The residual floodwater became a massive breeding ground for mosquitoes and other insects. As wolf spiders feed primarily on insects, that meant there was food aplenty.

"The amount of mosquitoes around would be incredible because of all this water," said Taronga Zoo spider keeper Brett Finlayson told the Sydney Morning Herald. "The spiders don't pose any harm at all. They are doing us a favor. They are actually helping us out."

As the soil begins to return to normal, some spiders will return to living underground, some may move on, while others will unfortunately become prey to birds and other small predators. It is expected that by the warm, dry days of summer, the population will have returned to normal.

I don't mind spiders. In fact, I'll leave the magazine or newspaper unrolled and will give them plenty of leeway since I know they help keep other insect populations in check.

But I'm still itching a bit just thinking about Australia's homeless arachnids.

Great Barrier Reef "At a Crossroads": UN group assesses reef in light of proposed coal and gas projects

Representatives from the United Nation's UNESCO World Heritage Centre's marine program have declared Australia's Great Barrier Reef "at a crossroads," following the group's initial assessment of the condition of the reef. The delegation's statement was in rebuttal to an Australian government position that the reef would be exposed to minimal impact from proposed coal seam gas developments.

Australia has rich deposits of coal seam gas, also known as coal bed methane, but its extraction method, wherein water is either forced into the coal bed or is extracted as a byproduct of the process, can produce pollution along with the environmental impact of the infrastructure (new roads, trucks, ships, etc.) required to support the coal seam gas operations.

According to UNESCO coordinator Dr. Fanny Douvere, the reef needs government protection ''not just for Australians but for humanity as a whole. We are not just talking about any barrier reef, we're talking about the Great Barrier Reef.''

With UNESCO declaring that the Australian government's position - that coal seam gas operations would have minimal impact on the reef - as one that might not be true, the government has now committed itself to an 18-month strategic assessment of future developments on the reef.

One area of concern will be the potential impact of dredging. As part of proposed developments, large areas of shoreline - up to 46 million cubic meters - would be dredged over the next 20 years. Dredging stirs up the bottom, potentially coating the coral with silt and affecting the photosynthesis process that feeds the microscopic zooxanthellae algae that lives within the coral's tissues and provides nutrients.

''We are aware dredging does have a correlation with water quality, and water quality is a crucial component for the conservation of the Great Barrier Reef as a whole,'' Dr Douvere said.

Another issue that will be studied is the increase in shipping anticipated either as part of coal and gas exploration or as a result of when operations are in earnest. The expansion of shipping and the toll it may take on the reef has not been lost on some within the Australian government.

Environment Minister Tony Burke said, "I have been making the argument for some time that shipping activity is potentially the most environmentally sensitive activity in the entire mix here. Any application that is going to have a continued marked increase, if it was successful on shipping movements, needs to be scrutinised incredibly closely and I view that as a critical part of any environmental approval."

Like many other developed nations, Australia is having to wrestle with the demands being made for more energy versus the preservation of its environment - with the Great Barrier Reef considered one of the world's grandest ocean treasures but one that is just as easily threatened as the smallest coral reef. In today's world, it's only as great as we wisely and thoughtfully allow it to be.

Of Nets and Neurotoxins: news items that could benefit sharks

Couple of interesting new shark items:

Anti-Shark Netting for Aquaculture
Sharks were recently in Las Vegas, and I don't mean the card shark kind. At a major aquaculture conference, a new proprietary shark-resistant netting was introduced which holds great promise in helping open-ocean aquaculture protect its harvest from curious sharks.

Open-ocean aquaculture primarily involves large pens that float at the surface and are big enough to allow species such as tuna reach a commercially-viable size. However, corralling fish together means that they will become a magnet for ocean predators like sharks, and previous netting material has not always done the job in resisting a hungry shark.

Working together, NET Systems and DSM Dyneema have developed PREDATOR-X, a netting that combines high-strength polyethylene fibers with stainless steel wire. It was field tested in the Bahamas by scientists from the Cape Eleuthera Institute, using the institute's aquaculture facility for full-grown cobia as the test guinea pig.

The results were positive. While the netting is able to withstand the abrasions and cutting of ocean predators, it is also lighter than other netting materials and allows for sufficient water flow which is important to aquaculture in maintaining a healthy level of oxygen for the fish.

Many times I have seen the tuna pens floating offshore off the Baja, Mexico coast and would wonder how many sharks died at the hands of armed aquaculture farmers protecting their stock. Now, perhaps both sharks and farmed fish will be able to coexist, saving a few sharks and some wild fish from commercial fishing in the process.

Neurotoxin Found in Shark Fins
A new study, released by Neil Hammerschlag of the University of Miami's R.J. Dunlap Marine Conservation Program and members of the Miller School of Medicine, has found potentially harmful levels of BMAA, a neurotoxin, in shark fins and related shark cartilage products from seven species of sharks in Florida. BMAA is associated with degenerative brain diseases such as Lou Gehrig's, Alzheimer's and Parkinson's.

Similar to other pollutants such as methylmercury that have been found in sharks and other large predators, the neurotoxin accumulation is a result of what is called biomagnification, a process whereby trace elements work their way up the predator-prey food chain. And as they do, their concentration levels increase. BMAA is found in cyanobacteria, an ocean bacteria, and from those humble beginnings it can move up through the various animals that feed on the bacteria and then preyed upon by others animals.

"The thing is very little has been done on BMAA because it is a new wave, a new understanding," says Hammerschlag. "We're only starting to understand the scope of the problem."

Given the documented evidence of biomagnification regarding other pollutants found in sharks and fish like tuna, the presence of BMAA does not come as a stretch of the imagination but you can expect pro-shark fishing industry forces to refute the findings as a scare tactic conjured up by anti-shark fishing advocates. One wonders who is the most scared by this development, those who consume shark products or those who are in the business of plundering one of the ocean's most vital inhabitants.

Marine Science Education: Malayasian group offers beginning courses for the curious

There are many armchair marine conservation and marine biologists out there; folks who cruise the Internet or read books to gain knowledge but don't have the time, inclination, or finances to get a formal degree. And that can be a fine approach - one shouldn't complain too much about enlightenment, whether it's formal or self-acquired - but, as "self-schooled," one could be subject to interpretation and misconception. A little structure can go a long way, particularly for young students impressionable and open for knowledge.

In Southeast Asia, the Tropical Research and Conservation Centre (TRACC) offers an interesting opportunity to get a structured introduction to marine conservation while at the same time enjoying the dive destinations of places like Borneo, Sipadan, and Malaysia. TRACC works with local resorts in putting together study & dive packages ranging from a concentrated 6-day course to a more lengthy 12-week course of study.

As a non-profit organization, TRACC is involved in coral reef and shark conservation and engages divers in volunteering to help support their research projects. The tie-in with dive resorts surely provides the group with some financial benefit while at the same time offering a method to alert divers to the issues threatening the biodiversity of these tropical regions.

However, I was a bit concerned as to the validity of the course, so I dug a bit deeper. The six-day diver course is TRACC's own invention and, while not formally accredited by any major educational institution, it is a clever value-added bonus to any diver seeking to get the most out of their dive experience.

The 12-week course is based on a curriculum offered through Cambridge University. TRACC's Marine Science A Level program, as it is called, follows a specific Cambridge syllabus and final examinations are offered by Cambridge to receive your full recognition for completing the course. The study course was designed primarily for young, college-level students and many colleges offer school credit for having completed the course. But it also offers benefits for older inquisitive minds or those contemplating a career in marine industries.

"TRACC is offering an internationally recognised marine science advanced (“A”) level from Cambridge Examination Board as a way to gain a useful qualification during a gap year or a volunteer programme (shorter alternatives are the 6 day courses). The advanced level Marine Science Course is for mature students who want to learn more, for students who want to study Marine Biology or Environmental Science at a university, or students who want to follow a career in shipping, fisheries, tourism or aquaculture," TRACC's website explains.

There are other marine conservation organizations that offer volunteer research opportunities that can provide a terrific learning experience. By coupling with a major educational institution like Cambridge University, TRACC is offering a more formal course of study that will hopefully educate Malaysian divers and students to the importance of preserving their natural resources and biodiversity while also providing a rewarding experience and point of personal recognition to international travelers as well.

Antarctic Ocean Alliance: committed to protecting critical areas in the Southern Ocean

The Antarctic's Ross Sea is considered by many to be one of the most pristine marine environments to be found down under. Facing New Zealand to the north, it has had proposals for basic protection sponsored by the United States and New Zealand, but now a more coordinated and international plan is being initiated, one that will possibly lead to the world's largest fully protected marine reserve.

The recently launched Antarctic Ocean Alliance (AOA) represents the coming together of several leading international conservation organizations, along with renown ocean conservation experts and even celebrities - all bound by one common purpose: to protect the Antarctic's marine resources. As a first step, they hope to establish a protected marine reserve in the Ross Sea, one that will ultimately expand to reach over 2.2 million square miles.

“The Ross Sea is one of the most amazing and relatively untouched marine environments on earth,” said the Alliance’s Chuck Fox. “While there are two proposals on the table to protect some of it, our report shows that we need a much broader and ecosystems-focused approach if we are to ensure this environment remains healthy and stable.“

The AOA includes, as its supporters, Greenpeace, WWF, Humane Society International, the Antarctic and Southern Ocean Coalition (ASOC), the Blue Marine Foundation (UK), Mission Blue (US), Oceans 5 (US), Deep Wave (Germany), The Last Ocean, Forest & Bird (NZ), the Environment and Conservation Organizations of New Zealand, and many others, along with individuals like oceanographer Dr. Sylvia Earle, entrepreneur Sir Richard Branson, and actor/conservation activist Edward Norton.

While the Commission for the Conservation of Antarctic Marine Living Resources (CAMLR) is the regulatory body that has agreed to work with AOA to establish a network of marine protected areas in and around the Ross Sea, they tend to work more behind the signs. The AOA will take a more proactive position when it comes to public exposure and media attention. This is meant to help ensure that all nations involved in implementing plans for marine protection will be better held accountable for the policies and plans they put in place.

“The fate of the Antarctic’s Ross Sea is likely to be decided by 24 countries and the EU this year and the global public knows nothing about it,” said Alliance Campaign Director Steve Campbell. “Now is the time to protect this amazing environment but we’ll need the global public involved to make that happen.”

Antarctic waters, which include the Southern Ocean, the Ross Sea, the Weddell Sea, and the Amundsen Sea, represents some of the richest marine ecosystems on earth with as many as 10,000 species calling it home. This environmental bounty has, over the years, been seen as a commercial bounty, too, with industrial fishing taking a heavy toll on many species.

The Antarctic Ocean Alliance seeks to curb commercial overfishing in the Antarctic and, with the Ross Sea protections as a start, the Alliance will be identifying 16 other critical habitats within the Southern Ocean that need protection.

Flying Squid: researchers study a potentially more efficient method of travel during migration

Now here's an odd bit of news.

Recent research presented at the 2012 Ocean Sciences Meeting in Salt Lake City, Utah, indicated that some species of squid could be using flying as a more efficient method of traveling long distances, like in seasonal migrations.

Oh, sure, squid can "fly" underwater using their siphon like a jet engine and the two fins framing the squid's mantle acting like wings. Sure, we've all seen that.

No. I'm talking airborne.

A team of researchers from Dalhousie University, Canada, and Stanford University, studied three species of squid and tracked the small orange-black squid leaping into the air off the coast of Brazil. Going airborne has long been recognized as a method that some squid will use to evade a predator. But what the researchers saw was repeated bursts into the air at a speed of fives time what the squid can achieve underwater. The theory is that to more efficiently use available energy as the squid continues through its long migration, it will choose to go airborne from time to time.

“As soon as we thought about the possibility that these things flew, it became plausible that these animals actually use flight as a way of reducing energy cost,” said Dalhousie University marine biologist Ronald O'Dor.

Other researchers tracked species like the Humboldt squid and found them covering distances greater than what their underwater speed suggested. Could they, too, be taking the occasional aerial stroll?

No one is suggesting extended flight; the squid has no way to sustain its flight through the air. However, with its powerful siphon capable of generating a sudden underwater thrust of jet propulsion, the idea of airborne squid is not that far-fetched of an idea. And it has been hypothesized that the squid's swimming fins have enough size and shape to act as ailerons, providing some measure of stability while aloft.

Not all scientists are convinced but they do find it tantalizing and are hoping for more research in the future to make a determination one way or another. For now, it's an interesting solution to the squid's ability to cover long distances.

Next it will be pigs.

Games for Nature: group explores video game potential to enlighten

I never caught on big with playing video games, but if the statistics are any indication, I am well headed towards becoming a card-carrying member of a shrinking minority.

• 500 Million people play online games for at least an hour a day, and the number is expected to grow to 1.5 billion in the next decade.
• People spend 3 billion hours each week playing online games.
• By the age of 21 American children have spent 10,000 hours playing games, as much time as they have spent in class from fifth grade.

So, with this much attention, time, and money spent on video games, it was inevitable that education would be drawn to the format as a viable learning tool. And that means that conservation and environmental education would not be far behind.

A new website has been launched, the brainchild of conservationist Bruno Monteferri, Cambridge University (a major supporter) conservation professor Bill Adams, and Chris Sandbrook, a member of the United Nations Environmental Programme. Games for Nature (www.gamesfornature.org) acts as an information source for interested gamers, developers, and researchers. The site lists current games available and acts as a networking resource to discuss ideas and opinions as to the viability, direction, and future of video games for conservation purposes.

It wasn't too long ago that educational video games were geared for younger children in keeping with the sophistication of the technology at the time. With the advances made since in graphics and platforms, from Playstations to iPhones, the average age of the user is now in their mid-30s. So, this provides opportunities to deliver more detailed, in-depth content that can enlighten users in direct and more subtle ways.

Subtle because, after all, it's a game that is meant to be entertainment, not a college lecture. But with the amount of time being spent playing video games, it can be an important avenue for getting conservation messages and a greater appreciation for nature integrated into the day-to-day thinking of a large segment of people.

Discussing a recent Cambridge-sponsored seminar and workshop, a Games for Nature spokesperson said, "Did we conclude that they were important? Absolutely: gaming is a deadly serious industry whose business depends on the pleasure it gives its customers – but it also has a vital role to play in shaping the way decisions are made about human use of nature.”

The Games for Nature website is a content-rich experience for anyone interested in learning either about specific games currently available or its potential as a conservation tool. The site has an extensive variety of videos, visual presentations, and reports on the subject - quite a treasure trove of information if you are interested. Games for Nature does not claim to have all the answers and nature-based video games could be a concept that could easily get bungled or squandered. However, serious conservationists need to examine every possible method by which they can connect with people. It has the potential to shape personal behavior and strengthen a constituency that could then impact the actions of policy makers.
