Archive of Digitized Analog Boomer Seismic Reflection Data Collected from Lake Ponchartrain, Louisiana to Mobile Bay, Alabama, During Cruises Onboard the R/V ERDA-1, June and August, 1992

In June and August of 1992, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the shallow geologic framework from Lake Pontchartrain, Louisiana, to Mobile Bay, Alabama. This work was conducted onboard the Argonne National Laboratorys R/V ERDA-1 as part of the Mississippi/Alabama Pollution Project. This report is part of a series to digitally archive the legacy analog data collected from the Mississippi-Alabama SHelf (MASH). The MASH data rescue project is a cooperative effort by the USGS and the Minerals Management Service (MMS). This report serves as an archive of high resolution scanned Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) images of the original boomer paper records, navigation files, trackline maps, Geographic Information System (GIS) files, cruise logs, and formal Federal Geographic Data Committee (FGDC) metadata. For more information on the seismic surveys see http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=1992-010-FA and http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=1992-037-FA These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.1992年6月与8月，美国地质调查局（U.S. Geological Survey, USGS）开展地球物理勘测，以调查路易斯安那州庞恰特雷恩湖至阿拉巴马州莫比尔湾一带的浅部地质构造。本次作业依托阿贡国家实验室的R/V ERDA-1号科考船完成，隶属于密西西比/阿拉巴马污染项目。本报告是密西西比-阿拉巴马陆架（Mississippi-Alabama SHelf, MASH）采集的遗留模拟数据数字化归档系列成果之一。MASH数据抢救项目是美国地质调查局与矿产管理服务局（Minerals Management Service, MMS）的合作项目。本报告归档了原始电火花震源纸质记录、导航文件、测线地图、地理信息系统（Geographic Information System, GIS）文件、航次日志，以及正式的联邦地理数据委员会（Federal Geographic Data Committee, FGDC）元数据的高分辨率扫描版标记图像文件格式（Tagged Image File Format, TIFF）与图形交换格式（Graphics Interchange Format, GIF）图像。 如需了解更多地震勘测相关信息，请访问：http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=1992-010-FA 与 http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=1992-037-FA 上述数据还可通过GeoMapApp（http://www.geomapapp.org/）与Virtual Ocean（http://www.virtualocean.org/）这两款地球科学探索与可视化应用获取。
