Sub-bottom Chirp profiling data (SEG-Y format) from eastern Long Island Sound, 2018
This sub-bottom Chirp profiling data set was 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 data files are in standard SEG-Y format. Funding was provided by the Long Island Sound Study and by the Connecticut Department of Energy and Environmental Protection (DEEP).
