Collaborative Research: Continued Study of Physical Properties of the WAIS Divide Deep Core

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 (WDC06A) 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. Visual stratigraphy of each ~1-m-long segment of the entire WAIS Divide main core was conducted by the same individual (Matthew Spencer). Data reported here are average annual thicknesses (second column, in meters) preceded by that average’s depth from the surface (in meters), averaged over ~50-m depth, which is the depth range recorded per log book.
