March through August Ice Edge Positions in the Nordic Seas, 1750-2002
Entry ID: G02169

[ Update this Record ]

Summary
Abstract: This product contains ice edge coordinates for the Nordic Seas from 1750 through 2002 for months March through August. Ice edge in this product is defined as the outer boundary of ice having at least 30% ice concentration. Data are derived from publicly available sea ice products and use observational data from ship logbooks, diaries and other sources in addition to more recent satellite data products from the Scanning Multichannel Microwave Radiometer (SMMR) and the Special Sensor Microwave Imager (SSM/I). The data are distributed via FTP in ASCII, JPEG, and shapefile format.

Quality There are some known limitations in the input data collections referenced in Divine and Dick (2006). March through August months were selected since these months contain a high data density. Therefore, the annual cycle of sea ice advance and retreat is not captured. See documentation for limitations by by data collection.
