The photo above, by Kyle McBurnie, won the University of Miami's Rosenstiel School of Marine and Atmospheric Science's 2013 Underwater Photography Contest that's open only to amateurs, defined as "photographers who earn no more than 20 percent of their income from photography." The beautiful beastie is a harbor seal (Phoca vitulina) in a kelp forest at Cortes Bank, about 100 miles west of San Diego, California.
This video was made by Henry Kaiser, a musician and research diver who guest blogged here yesterday about the problems caused by thinning sea ice in Antarctica. The film takes you on a tour of McMurdo Station and the research being done there by Gretchen Hoffman of the University of California Santa Barbara.
Kaiser dives for different researchers every year. This year, he's working with Hoffman's team, helping them study the effects of climate change on ocean life. Specifically, Hoffman has Kaiser out collecting Antarctic sea urchins so that her team can extract the animals' sperm and eggs to test the development of sea urchin zygotes in differing conditions of PH and temperature.
There's great footage in here of human life above the ice, and animal life below. It's a bit long, but I recommend taking the time to watch the whole thing.
