Here is a KML file of all submarine (yellow), mooring (green), and Airborne-EM (red) data locations. Each data point is mapped and the source, platform, date, and the draft or thickness value are displayed (updated 4/2/12).

Comparison of uCDR mean ice thickness from all (non-satellite) sources. Small dots are individual monthly means from Observations and PIOMAS 20C at the time (month/year) and location of the Observation. Thick lines correspond to annual averages. PIOMAS 20C is a PIOMAS integration using ERA-20c atmospheric forcing.

Locations uCDR ice thickness data and comparisons with PIOMAS sea ice model. Only non-satellite data are plotted.


From Lindsay and Schweiger, 2015. Coefficients of the ITRP indicator variables for fits that leave one data source out at a time for the Arctic Basin, 2000–2012. The coefficients for each source are grouped together. Grey bars show the coefficients for a fit that includes all of the observations, and bars in other colors indicate which source has been left out as shown by the colors of the diagonal labels (same order as the bars). The black lines give the 1 interval for the coefficients. ICESat-G is always the reference.
