The movements of two gigantic Antarctic icebergs appear to have dramatically reduced the number of Emperor penguins living and breeding in a colony at Cape Crozier, according to two researchers who visited the site last month. The colony is one of the first ever visited by human beings early in the 20th century.
"Its certain that the number of breeding birds is way down" from previous years, said Gerald Kooyman, a National Science Foundation-funded researcher at the Scripps Institution of Oceanography in La Jolla, Calif.
Kooyman took aerial photos of the colony in August during the flight missions that preceded the official start of the Antarctic research season. He returned to visit the colony in October, after the season was underway, with Paul Ponganis, another NSF-funded Emperor researcher who also is at Scripps.
