Sea-ice Thickness and Draft Statistics from Submarine ULS, Moored ULS, and a Coupled Model, Version 1

Published by NSIDC | National Aeronautics and Space Administration | Metadata Last Checked: February 21, 2026 | Last Modified: 2026-02-17
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.
