A largely unexplored sea-ice data record consists of in situ thickness measurements derived from drill holes, cores, gauges, thermistor strings and surface electromagnetic induction. By compiling these often disparate and scattered but generally highly accurate measurements into a single database, a long-term record is being developed that will expand and extend in time and space the thickness record obtained from the submarine ice draft record as well as the developing satellite, helicopter EM, and sonar and mass-balance buoys measurements. From journal articles, reports, on-line databases and direct contact with sea-ice investigators, we assembled measurements from many types of expeditions, large and small, with the earliest data so far from 1928 to the most recent from 2007. Many of the field expeditions are in regions outside of the central Arctic region that submarines are able to sample, thereby expanding the spatial extent of the sea-ice record. We will discuss the preliminary analysis of these records, as a means to improving the understanding of thickness changes in relation to climate change. Since January 2009, a seed effort began with the considerable and enthusiastic efforts of a JPL undergraduate student intern, Katherine Melocik. The compiled measurements, quality estimates and documentation were collected and formulated into a data format suitable for analysis that will be made available in a central archive for distribution and continued expansion/growth. Adding a visual dimension to the archive, a GoogleEarth map was constructed to illustrate when and where the ice-thickness measurements were taken. While the archive is far from being completed, the data collection is beginning to feel substantial enough to start a preliminary analysis on these records, to assess the changes in Arctic sea-ice thickness over many decades.
