One-Minute Navigation Shapefile of Seismic-Reflection Data Collected in Western Rhode Island Sound (N80_1_1MINNAV_SORT.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”号考察船，在罗得岛海峡西部开展了采用Uniboom地震系统的反射地震勘探作业。本次航次分为2个勘探段，总时长共计8个勘探日。本次勘探获取的数据以模拟格式记录，并归档于美国地质调查局。
鉴于近期学界对罗得岛海峡地质的研究兴趣，同时为在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被扫描并转换为TIFF图像与SEG-Y数据文件。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；该坐标数据以ESRI形状文件（ESRI shapefile）格式提供，同时另有以空格分隔的文本格式文件，其中包含东向与北向平面坐标。
