Summary
Abstract: 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 ... View entire text
