The Website is dedicated to monitoring and analysing changes in the polar regions. Current products include sea ice area & thickness, snow cover, high Arctic temperature data, ice sheet bedrock elevation and a quantification of ocean warming from reduced sea ice.

Freezing Degree Days

The graphs show the Freezing Degree days over the whole freezing season. The sea ice thickness can be estimated based on the following formula (Lebedev 1938)
Thickness (cm) = 1.33 * FDD (°C)^0.58
