Weekly Arctic Landfast Ice Extent from 1976 to 2007

This data set contains time series of weekly arctic landfast ice extent from 1976 to 2007. The time series were computed using the weekly or biweekly ice charts produced by the U.S. National Ice Center (NIC). The original gridded sea ice charts are archived at National Snow and Ice Data Center, at http://nsidc.org/data/G02172.html. Please see README file for more detailed data description.
