Navigation Tracklines of Atwater Valley Multichannel Seismics Survey Collected During USGS Gyre Cruise G1-03-GM (03001) - G1CDP_NAV_AV_GEO

This point shapefile contains navigation of the shot points for the multichannel seismic survey that was conducted in the Atwater Valley area of the Gulf of Mexico 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 253 km of data were collected along 35 short lines in and around lease block Atwater Valley 14 on the floor of the Mississippi Canyon.

本点形状文件（Point Shapefile）收录了2003年5月，由美国地质调查局（USGS）G1-03-GM航次搭载“回旋号”研究船（R/V Gyre）在墨西哥湾阿特沃特谷区域开展的多道地震勘探（Multichannel Seismic Survey）的炮点导航数据。本次航次的任务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。本次作业在密西西比峡谷海底的阿特沃特谷14号租赁区块及其周边区域，沿35条短测线完成了总长约253千米的数据采集。
