Monthly Average Polar Sea-Ice Concentration

U.S. Geological Survey Digital Data Series DDS-27
Version 1.0

By Peter N. Schweitzer


The purpose of this data set is to provide paleoclimate researchers with a tool for estimating the average seasonal variation in sea-ice concentration in the modern polar oceans and for estimating the modern monthly sea-ice concentration at any given polar oceanic location. It is expected that these data will be compared with paleoclimate data derived from geological proxy measures such as faunal census analyses and stable-isotope analyses. The results can then be used to constrain general circulation models of climate change.
