NOAA's Aquarius: an undersea home for scientists, divers and even astronauts

Where would you like to spend a faraway vacation? A remote chateau in France? A cozy cabin in the high Sierras? Well, here's one that is on my wish list: over 60 feet below the surface of the waves, off the coast of Florida, nestled in the Aquarius undersea research station.

Currently, the only permanent undersea habitat and research facility, Aquarius is owned and funded by the National Oceanic and Atmospheric Administration (NOAA) and operated by the University of North Carolina Wilmington. It has been home to a wide array of scientists and researchers since it was first deployed in the Florida Keys Marine Sanctuary in 1993.

One of the advantages of an undersea habitat is the ability to extend the amount of bottom time (time spent diving and conducting research outside). If you were to dive from the surface to 60 feet, you would have only about one hour of dive time before you would find yourself having to deal with decompression (waiting to discharge accumulated nitrogen) as you surfaced. However, by staying below in a pressurized facility, a scientist could spend a full working day outside, for up to 10 days or more. At the conclusion of the mission there would then be an extended period of time spent decompressing before stepping on dry land, but the ability to spend days at a time underwater is extremely valuable for many types of scientific ocean studies.

Additionally, a facility like Aquarius is ideal for testing how men and women can function in confined environments like they would encounter in deep space missions. NASA just concluded its latest deep space training exercise, NEEMO 15, which stands for NASA Extreme Environment Mission Operation. With NASA's future deep space missions, like ones being considered to the moons of Mars, Mars itself, and even to an asteroid (calling Bruce Willis), it is important to know how astronauts can function effectively and independently, with little or no contact with mother Earth. Medical emergencies, software and hardware repairs, and of course, long-term isolation - all need to be considered and studied.

From reef growth to acidification to developing new techniques in biodiversity studies - or even preparing astronauts for future space missions - Aquarius is a vitally important ocean research center. NOAA understands the value of public awareness and has established and interesting website for Aquarius, containing background information on missions and other accomplishments, videos, pictures, and even a live feed camera for when it's catering to visitors.

So, champagne and strawberries in a New York hotel suite? Fresh tempura in a Tokyo high-rise? A warm fire and a soft couch in Yosemite? All very nice, but give me a cup of hot chocolate, a bunk, a porthole, and a set of diver gear at the ready and I'll be just fine, thank you.

Deep Sea Observatory: live from downtown Monterey Bay canyon

After six years of design, preparation and installation, the Monterey Bay Aquarium Research Institute (MBARI) has launched a revolutionary research observatory that will serve as a power station and data link for many deep sea projects. At 3,000 feet deep, perched on the edge of the Monterey Bay undersea canyon, the Monterey Accelerated Research System (MARS) provides organizations with properly configured experimental equipment with the ability to efficiently gather critical data on oceanic conditions - whether it be sealife studies or monitoring water quality or climate change effects.

Where research equipment is often hampered by battery or power limitations and researchers must often wait until data is retrieved, the MARS system will act as a round-the-clock "power strip" and "high-speed internet connection." One of the first experiements to utilize MARS will be one that monitors acidity levels. Ocean acidification is a major issue tied in to the ocean's interaction with carbon dioxide levels. (Read MBARI news release.)

Speaking of ocean acidification, the NGO, the Center for Biological Diversity, has notified the Environmental Protection Agency (EPA) of its intent to file a lawsuit against the EPA, demanding that the U.S. federal agency act more aggressively regarding the issue of ocean acidification due to increasing carbon dioxide absorption. In particular, the suit addresses the need for the EPA to revise its outdated ph standards - set in 1976 - in light of new research regarding acidification. Higher ph levels due to carbon dioxide absorption can have profound negative effects on a variety of marine life and can threaten the overall health of any marine ecosystem. (Read press release.)

“Ocean acidification is global warming’s evil twin,” said Miyoko Sakashita, an attorney with the Center for Biological Diversity’s oceans program. “The EPA has a duty under the Clean Water Act to protect our nation’s waters from pollution, and today, carbon dioxide is one of the biggest threats to our ocean waters.”

Let's hope that both MARS and the Center for Biologival Diversity can help to enlightened those goverment agencies that we depend on to make important environmental decisions.
