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. Work in 2013 under this grant consisted of 4 basic tasks: (a) a regression analysis of the effect of ship depth and speed on mean draft and other statistics, (b) development of software to process both digital and analog data, (c) processing and analysis of data from two cruises in 2011 and (d) beginning processing of older analog data.
