View colorful highlights of deep-sea marine life from the Gulf of Alaska, including fan corals, vase sponges, basket stars and squid. This video comes from a NOAA Office of Ocean Exploration mission to study unexplored seamounts in the Gulf of Alaska. 13 dives were made in the titanium-hulled submersible Alvin to collect this fascinating video from more than 3000 feet below the surface of the sea. http://www.oceanexplorer.noaa.gov/explorations/02alaska/logs/summary/media/movies/02alaska_deepseacoral_h.264.m4v Wed, 23 August 2006 16:30:00 GMT 8:30 Gulf of Alaska, Gulf of Alaska 2002, Gulf of Alaska Exploration, Peter Etnoyer http://www.oceanexplorer.noaa.gov/include/images/ocean_explorer_podcast_300.jpg http://www.oceanexplorer.noaa.gov www.oceanexplorer.noaa.gov (June 27 - July 26, 2005) Experience what it is like to be an Ice diver studying the density of creatures living on the underside of ice floes. While much of under-ice diving is similar to regular diving, there are a few important differences. First, the divers wear drysuits instead of wetsuits. These dry suits are sealed at the wrist and the neck and don't let any water in beyond the seals. Second, under-ice diving is usually performed using compressed air, not other mixed gases and the regulators used are specifically designed to be used in temperatures below freezing. Most different from regular diving operations, under-ice divers are tethered to the surface.

These eels, which have now been identified as Dysommina rugosa, are the only common metazoan (multicellular) animals occupying these low-temperature hydrothermal vents. The Crevices at 708 meters (2323 feet) of a hydrothermal vent site are occupied by thriving aggregations of cutthroat (synaphobranchid) eels. These eels, which have now been identified as Dysommina rugosa, are known from trawl samples in both the Atlantic and Pacific oceans, but have never before been studied in their natural habitat. The only common metazoan (multicellular) animals occupying these low-temperature hydrothermal vents, preliminary work indicates that they use the vent only as a place to live. They seem to feed not on chemosynthetic bacteria, but on crustaceans that pass by Nafanua’s summit in the currents. Image courtesy of UCSB, Univ. S.
