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.

本数据集由地面冰穿透雷达探测获取，采集工作作为美国国际横穿南极科学考察队（US ITASE）在西南极考察路线的一部分，于2001年11月1日至2003年1月10日期间开展。考察期间以约12米的间隔采集了经度、纬度、冰厚以及显著内部反射层的深度数据。本次考察路线中约90%的路段可获取冰厚数据，约80%的路段可获取内部层位深度数据。数据集可通过文件传输协议（FTP）获取，格式包含ASCII与JPEG。
