Southern Hemisphere sea surface temperature images - in development
Most of these images are updated either daily or monthly. Images of Southern Hemisphere (Antarctic) sea ice trends are generally static - but may be updated periodically (eg at the end of the year). Please note that this is a research project. Definitions of some sea ice terminology are available from the definitions page.
Data used to produce the NASA Goddard Space Flight Center (GSFC) sea ice concentration images are provided by NSIDC. They are obtained from the Nimbus-7 SMMR and DMSP SSM/I Passive Microwave radiances at a resolution of 25 x 25 km. Anomalies are calculated from the 1979-2008 climatology. Citations for the data are:
