Sediment grab descriptions (Shapefile format), western Long Island Sound (2023)

This ESRI Shapefile provides sediment description information for samples obtained with a Ponar grab sampler during R/V Lowell Weicker surveys of western Long Island Sound in June 2023. The sampling was done as part of the Long Island Sound mapping project Phase 3A. A photo of each sample was taken and the samples were described visually in the field. Based on the findings a preliminary lithology was determined. A sub-sample of the top two centimeters was taken and stored in a jar for later analysis. Sample location is based on the ship DGPS system. There is an accompanying Excel spreadsheet. This project was made possible by the Long Island Sound Research and Restoration Fund, established by a Memorandum of Understanding among the members of the Policy Committee of the Long Island Sound Management Conference and administered by Long Island Sound Cable Fund Steering Committee.
