Description:Arctic sea ice is the frozen interface between the ocean and the atmosphere. It reduces the absorption of solar energy because of its high albedo relative to the darker open ocean surface. In addition, as a physical barrier, it modifies the heat and moisture transfer between the atmosphere and ocean. Sea ice plays a key role in the ecosystem, providing an essential habitat for marine life and modulating the biogeochemical balance of the Arctic. The sea ice cover has long played a practical and cultural role in Indigenous communities of the north. Sea ice historically limited national and corporate activities in the Arctic, but decreased ice cover is influencing commercial transportation, resource extraction, and national security.
