AGDC Releases Average Annual Layer Thickness of the WAIS Divide Ice Core from Visual Stratigraphy Data

The Antarctic Glaciological Data Center (AGDC) at NSIDC is pleased to announce the release of a new data set, Average Annual Layer Thickness of the WAIS Divide Ice Core from Visual Stratigraphy. This data set includes ~50 m averaged annual layer thicknesses down to 3403 m depth at the West Antarctic Ice Sheet (WAIS) Divide ice core as observed visually using diffuse transmitted light opposite a planed surface in a light-shielded booth in the core-processing line at the National Ice Core Lab in Denver, CO.
