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.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
