Arctic Ice Products
The Arctic region is a main area for ice analysis by the U.S. National Ice Center. The Arctic is analyzed by concentration daily, with a more detailed analysis containing concentration and thickness completed weekly. Based off these analyses, numerous products are created and disseminated here. Periodic products like the Sea Routes and Outlooks are also placed here.
