Images showing the retreat of sea ice and subsequent chlorophyll-a bloom in the spring/summer of 1997/98-2009/10, East Antarctica.
Listed in NASA Earthdata CMR
This data set comprises animations showing the spring/summer melt of sea ice in East Antarctica and the subsequent chlorophyll blooms.
Description
SMMR-SSM/I sea ice concentration data were obtained from the National Snow and Ice Data Centre, and AMSR-E sea ice concentration data from the University of Bremen. SeaWiFS and MODIS chlorophyll-a data were obtained from the OceanColor site.
SeaWiFS and SMMR-SSM/I data were used for seasons prior to 2002/03; MODIS and AMSR-E data were used for later seasons. Chl-a data were averaged over 16-day periods. The animations also show the ETOPO2 bathymetry and the fronts of the Antarctic circumpolar current (Orsi et al. 1995).
