Recurring Spring Leads and Landfast Ice in the Beaufort and Chukchi Seas, 1993-2004

National Snow and Ice Data Center (NSIDC) - In the Beaufort and Chukchi Seas, the most significant sea ice anomalies have occurred in the summer ice extent (Eicken et al. 2006). In addition, there has been a considerable decline in the multiyear ice pack in this region (Eicken et al. 2006). To help understand these anomalies, this data set contains information on recurring spring leads and landfast ice extent in this area. This data set...
