An Emperor penguin dives through a hole into the water below the McMurdo Sound sea ice.

June 8, 2010
An Emperor penguin dives through a hole into the water below the McMurdo Sound sea ice. Dr. Paul Ponganis from Scripps Institution of Oceanography and his team study Emperor penguins' diving. The routine occurrence of 500-meter dives during foraging trips is a physiological and behavioral enigma. Ponganis examines pressure tolerance, management of oxygen stores, end-organ tolerance of diving hypoxemia/ischemia, and deep-dive foraging behavior. This information provides 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. To learn more about Dr. Ponganis' research, visit http://antarctic.ucsd.edu.
