Shotpoint navigation for Keathley Canyon Multichannel Seismics Survey Collected During USGS Cruise G1-03-GM (03001) - G1CDP_NAV_KC_GEO.SHP

The point shapefile contains the shotpoint navigation for the Keathley Canyon multichannel seismic survey collected during USGS cruise G1-03-GM aboard the R/V Gyre in the Gulf of Mexico in May, 2003. The purpose of this cruise was to collect multichannel seismic data in support of USGS and Department of Energy gas hydrate studies. About 786 km of data were collected along 59 lines in and around lease block Keathley Canyon 195.

本点形状文件（point shapefile）涵盖基思利峡谷（Keathley Canyon）多道地震勘探的炮点导航数据，该数据采集自2003年5月美国地质调查局（USGS）搭载吉雷号（R/V Gyre）研究船在墨西哥湾执行的G1-03-GM科考航次。本次航次的核心目标为采集多道地震数据，以支撑美国地质调查局与美国能源部的天然气水合物研究工作。本次航次在基思利峡谷195租约区块及其周边布设59条测线，累计采集约786千米的地震数据。
