Sub-bottom Chirp profiler track lines (Shapefile format) from eastern Long Island Sound, 2018
This shapefile shows the track lines of the sub-bottom Chirp profiler data set acquired in eastern Long Island Sound using an EdgeTech Chirp 424 system with a sweep frequency of 4-24kHz. The data set was collected using small boats in April 2018, and lines were run in north-south and east-west directions lines. The sub-bottom surveys were conducted in order to guide subsequent sediment coring. The shapefile is in ESRI SHP format. Funding was provided by the Long Island Sound Study and by the Connecticut Department of Energy and Environmental Protection (DEEP).
