GCOS Ocean Physics ECV - Sea Ice

Sea ice is a sensitive indicator to changes in the energy absorbed by the ice. It also greatly influences the surface albedo and air–sea exchanges of energy, moisture and carbon. The sea-ice distribution, including polynyas and margins, also has an important influence on marine ecosystems. Changes in the distribution of sea ice affect these ecosystems and a number of activities such as shipping, logistic and tourist operations.
