Antarctic Products

The Antarctic region is a main area for ice analysis by the U.S. National Ice Center. Antarctica 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 presented here. There are also periodic products like the Ross Outlook and Peninsula charts placed here during its melt season. The USNIC is also charged with naming and monitoring large icebergs in Antarctica.
