Four decades ago, Paul Dayton, a gutsy benthic ecologist, plunged into the -2° C waters below the Antarctic sea ice, sinking as far as 61 meters to study this unique ecosystem of sponges, colorful sea stars, and other bottom crawlers. "I remember being so cold and miserable and crying daily," Dayton recalls from the warmth of the Scripps Institute of Oceanography in San Diego, where he has been a professor for 38 years. "But the dives themselves were so amazing and wonderful."
