AGDC Releases WAIS Divide Sonic Log Data

The Antarctic Glaciological Data Center (AGDC) at NSIDC is pleased to announce the release of a new data set, WAIS Divide Sonic Log Data . This data set contains a record of speeds for vertically-propagating compression-waves measured throughout the depth of ice that surrounds the WAIS-D borehole. Multiple logs provide redundant measurements for all depths. Data for individual wave-speed measurements were included, as well as 3 m running averages for each log. A Takeaway Profile that represents our interpretation of the combined data set is also included.
