Sleeping with the Fishes

Of course, I can't forget what everyone always wants to know-where do you relieve yourself? There is a curtain-enclosed toilet inside, which lacks privacy and has a tendency to clog. So many aquanauts choose the other option-to become one with the sea, or do it with the fishes, so to speak. There is a problem, though. Human wastes are tasty food for fish, and some can be a bit aggressive. I'll leave the rest to your imagination.

Typically, to do a mission in Aquarius, scientists write a proposal to the National Oceanic and Atmospheric Administration (NOAA) and the University of North Carolina at Wilmington, which run the program. Once accepted, the proposals are culled by a panel of experts. Results from research conducted in Aquarius have brought us important insights into coral reefs, particularly those along the Florida Keys. For instance, Aquarius-run experiments found that too much sunlight can damage corals even down to a depth of 80 feet. Many corals have thus evolved a chemical block to prevent sun damage. In fact, in Australia, scientists have isolated chemicals from corals now used in sunscreens for people. One of the big questions in Florida concerns water quality and coral-reef health. From Aquarius, researchers have examined the surrounding waters for pollution. Surprising to many, so far no evidence of poor water quality has been detected in the area. Pollution has been documented close to shore. But many of Florida's coral reefs are farther seaward, and one of the planet's strongest ocean currents, the Gulf Stream, flows nearby, flushing the reefs with clean, clear water. Aquarius scientists also discovered that nutrient-rich water periodically impinges on the reefs from deep in the ocean because of naturally occurring underwater waves and currents. Researchers continue to investigate the impact of natural factors and human influences on the health of Florida's coral reefs.

I was lucky enough to do another mission in Aquarius in 2000, this time for a full two weeks. I truly relish all of my time both at Hydrolab and Aquarius and enjoy sharing these experiences with others to inspire them to learn more and care more about the ocean. For without public understanding and stewardship, our oceans are at risk. While lately my time in the sea has been limited to going for long swims in the beautiful Gulf, I look forward to getting my gills wet in the years to come and learning even more about the wondrous world beneath the waves.
