One-Minute Shot Point Navigation for Seismic-Reflection Data from Southern Rhode Island Sound Collected in 1980; Formatted for Use With Landmark (A80_6_SHOTNAV.TXT)

During 1980, the U.S. Geological Survey (USGS) conducted a seismic-reflection survey utilizing Uniboom seismics in southern Rhode Island Sound aboard the Research Vessel Asterias. This cruise totalled 3 survey days. Data from this survey were recorded in analog form and archived at the USGS. Due to recent interest in the geology of Rhode Island Sound and in an effort to make the data more readily accessible while preserving the original paper records, the seismic data from this cruise were scanned and converted to TIFF images and SEG-Y data files. Navigation data were converted from LORAN-C time delays to latitudes and longitudes, which are available in ESRI shapefile format and as eastings and northings in space-delimited text format.

1980年，美国地质调查局（U.S. Geological Survey, USGS）搭乘“阿斯特里亚斯号（Research Vessel Asterias）”研究船，在罗得岛海峡南部开展了采用Uniboom地震勘探技术的地震反射勘探作业。本次航次共计3个勘测日，所采集的数据以模拟格式记录并存档于美国地质调查局。鉴于近期学界对罗得岛海峡地质研究的关注度提升，同时为在保留原始纸质记录的前提下提升数据的可访问性，研究人员将本次航次的地震数据扫描并转换为TIFF图像与SEG-Y数据文件。导航数据由罗兰-C（LORAN-C）时间延迟参数转换为经纬度坐标，该数据以ESRI形状文件（ESRI shapefile）格式提供，同时还以空格分隔文本格式提供了东向、北向坐标数据。
