Recent changes in the extent and stability of ice shelves in the Antarctic Peninsula prompted NSIDC to begin a monitoring program using data from the AVHRR Polar 1 km Data Set. NSIDC regularly reviews images of those ice shelves considered susceptible to rapid change due to climatic warming, and of several other major shelves that occasionally calve major icebergs.
The images in this site represent a selected subset of the available scenes, generally the clearest and most informative scenes available. The scenes are derived from either the AVHRR visible (vis) or thermal (temp) channels, enhanced by combining two channels using principal components processing. In the thermal images, bright areas are colder areas. A few additional scenes from other sensors (MODIS, Landsat) are included to provide some supplemental information on ice shelf structure and events.
