Ice Thickness and Internal Layer Depth Along the 2001 and 2002 US ITASE Traverses

Ice thickness and internal layer depth data were collected with a ground-based, ice-penetrating radar study as part of the US International Trans-Antarctic Scientific Expedition (US ITASE) traverse in West Antarctica from 01 November 2001 to 10 January 2003. Longitude, latitude, ice thickness, and depth to a prominent internal reflector were collected at approximately 12 m intervals. Ice thickness values are reported for approximately 90% of the traverse, and internal layer depth values are reported for approximately 80% of the traverse. Data are avaialble in ASCII and JPEG formats via FTP.
