Processing of Older Submarine Ice Draft Data.

摘要

Arctic sea ice thickness is critical to geophysical research into climate change, shipping, biological productivity and other things. The overall goal of this work is to produce a public archive of ice draft data for research. The data is meant to span the largest time range possible and be of the highest possible quality. In addition the data must include detailed and accurate documentation. Processing of draft data requires sophisticated image processing software. By developing software to process ice draft data we now have the capability to produce data that significantly increases the time span covered by the draft data. The current archive covers 26 years from 1975 to 2005. With new software we have have extended that record from 1960 to 2011 or a span of 51 years.
