Short summary
The sea ice thickness of the Arctic Basin is estimated from sources that include upward-looking sonars, electromagnetic sensors, and lidar or radar altimeters. Good agreement is found between five of the systems while larger systematic differences are found for others. The trend in annual mean ice thickness, 2000--2013, is –0.58–/+0.07m decade–1; for the central Arctic Basin alone the annual mean ice thickness has decreased from 3.45m in 1975 to 1.11m in 2013, a 68% reduction.
