Seal Nose

July 8, 2010
Seal Nose The nose of a Weddell seal pokes through a hole in the ice. The photo was taken on the sea ice of McMurdo Sound at Penguin Ranch, an Emperor Penguin study site. Studies of seals is just one of the vast numbers of ongoing research projects that take place continually in Antarctica under the U.S. Antarctic Program (USAP), supported and managed by the National Science Foundation. For example, one study by researchers from Scripps Institution of Oceanography focused on Emperor penguins' diving. Emperors routinely dive to depths of 500-meters. Scripps researchers examined the Emperors pressure tolerance, management of oxygen stores, end-organ tolerance of diving hypoxemia/ischemia, and deep-dive foraging behavior. This information provided insight into human diving physiology and has medical applications for patients whose organs or tissues have been deprived of oxygen due to heart attack, stroke, transplant, etc. Other Antarctic study areas are aeronomy and astrophysics, biology and medicine, geology and geophysics, glaciology, and ocean and climate systems. Outreach, such as the Antarctic Artists and Writers program, and education programs are also supported. To learn more, visit the USAP Web site. (Date of Image: 2007)
