Ship Tracklines for Seismic-Reflection Data Collected in Western Rhode Island Sound (N80_1LINES.SHP)

During 1980, a seismic-reflection survey utilizing Uniboom seismics was conducted by the U.S. Geological Survey (USGS) in western Rhode Island Sound aboard the Research Vessel Neecho. This cruise consisted of 2 legs totalling 8 survey days. Data from this survey were recorded in analog form and archived at the USGS. As a result of 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“Neecho”号研究船，在罗得岛湾西部开展了采用单波束地震（Uniboom）系统的反射地震勘探作业。本次勘探分为2个航次段，累计作业8天。勘探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湾地质研究的关注度不断提升，为在完整保留原始纸质记录的前提下提升数据可及性，研究人员将本次航次的地震数据扫描转换为TIFF图像（TIFF）文件与SEG-Y数据文件（SEG-Y）。导航数据原以罗兰-C（LORAN-C）时间延迟格式存储，现已转换为经纬度坐标；该导航数据可通过ESRI形状文件（ESRI shapefile）格式获取，同时也以空格分隔文本格式提供东向与北向坐标数据。
