NSIDC: Arctic Sea Ice Extent Standardized Anomalies Jan 1953-Oct 2008Entry ID: NSIDC_ArcticSeaIceExtent1953-2008
Abstract: Passive microwave satellite data reveal that, since 1979, winter Arctic ice extent has decreased about 4.2 percent per decade (Meier et al. 2006). Antarctic ice extent is increasing (Cavalieri et al. 2003), but the trend is small.
Satellite data from the SMMR and SSM/I instruments have been combined with earlier observations from ice charts and other sources to ... yield a time series of Arctic ice extent from the early 1900s onward. While the pre-satellite records are not as reliable, their trends are in good general agreement with the satellite record and indicate that Arctic sea ice extent has been declining since at least the early 1950s.
Sea ice extent departures from monthly means for the Northern Hemisphere. For January 1953 through December 1979, data have been obtained from the UK Hadley Centre and are based on operational ice charts and other sources. For January 1979 through September 2008, data are derived from passive microwave (SMMR / SSM/I).
