Penguin Diving Study (Image 2)
An emperor penguin dives through a hole in the sea ice into the water below McMurdo Sound. 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 Ponganis' research, visit http://antarctic.ucsd.edu.
