Recurring Spring Leads and Landfast Ice in the Beaufort and Chukchi Seas, 1993-2004
Entry ID: G02173

[ Update this Record ]

Summary
Abstract: 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 ... View entire text

Quality Note: NSIDC did not perform a quality assessment of the data. Landfast Ice Extent: The manual process for identifying landfast ice extent has subjectivity. However, this subjectivity was reduced by using a gradient difference. Refer to the landfast ice extent Data Processing section of this document for more information on the gradient difference. The following is a list of the quality checks ... View entire text
