U.S. National Ice Center Daily Marginal Ice Zone Products, Version 1

Published by NSIDC | National Aeronautics and Space Administration | Metadata Last Checked: February 21, 2026 | Last Modified: 2026-02-17
The marginal ice zone (MIZ) is defined by the World Meteorological Organization (WMO) as “the region of an ice cover which is affected by waves and swell penetrating into the ice from the open ocean” (WMO, 2014). This data product is a U.S. National Ice Center (USNIC) rendering of the MIZ as the band of ice in concentrations between 1/10 and 8/10, or about 10% to 80% concentration, that surrounds Arctic and Antarctic pack ice with higher concentrations. The time series begins in September 2004 for the Arctic and January 2010 for the Antarctic.
