Sea Ice Observations from the Akademic Fedorov (40th Russian Antarctic Expedition)Entry ID: ASPECT_AF040595
Abstract: Monthly-averaged Antarctic sea ice extents derived from satellite passive microwave radiometers (from the Nimbus 7 Scanning Multichannel Microwave Radiometer (SMMR) and the DMSP F8, F11, and F13 Special Sensor Microwave Imagers (SSMIs)) for the 28-year period 1979-2006 show an increase of 1.0 +- 0.4% per decade. This overall increase results from contrasting trends in five regional sectors: the ... Weddell Sea, the Indian Ocean, the Western Pacific Ocean, the Ross Sea, and the Bellingshausen/Amundsen seas. The most striking feature of this figure is how different the monthly trend patterns are for the five sectors. The Weddell Sea and Western Pacific Ocean have mostly positive values occurring during the first half of the year. The Indian Ocean sector also has mostly positive trends but has its largest values during the last half of the year. The Ross Sea has positive trends for all twelve months and for most months has the largest positive trends of all five sectors. Only the Bellingshausen/Amundsen Seas sector has negative trends for each month, with the largest negative trends December, January, and February. For the Southern Hemisphere as a whole all twelve months exhibit positive trends, with the smallest occurring in December and the largest in May. Credit: Donald J. Cavalieri and Claire L.
