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”研究船（Research Vessel Asterias），在罗德岛湾南部海域开展了采用Uniboom地震勘探技术的反射地震调查。本次航次共计3天。本次调查获取的数据以模拟格式记录，并归档于美国地质调查局。鉴于近期学界对罗德岛湾地质研究的关注度日益提升，为在完整保留原始纸质记录的前提下提升数据可获取性，本次航次的地震数据已完成扫描，并转换为TIFF图像文件与SEG-Y数据格式文件。导航数据已从罗兰-C（LORAN-C）时间延迟值转换为经纬度坐标，该导航数据以ESRI形状文件（ESRI shapefile）格式存储，同时还以空格分隔的文本格式提供东向与北向平面坐标。
