This data set consists of estimates of mean values of sea-ice thickness and sea-ice draft in meters computed from three different input data sets: sea ice draft from Upward Looking Sonar (ULS) mounted on submarines, sea ice draft from ULS mounted on bottom-anchored moorings, and a simulated ice-thickness model. The data span from 1979 to 2004 and cover two regions centered around the North Pole. One region, Region A, is north of 89 degrees N; and the other, Region B, is north of 87 degrees N. The data set consists of one ASCII text file. The data are available via FTP.
