Abstract:
This ESRI Shapefile provides sediment description information for samples obtained with a modified van Veen grab sampler during R/V Pritchard and R/V Seawolf surveys of eastern Long Island Sound in August and November 2023. The sampling was done as part of the Long Island Sound mapping project Phase 4B. 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 D-GPS system. There is an accompanying Excel spreadsheet. The work was funded with CT DEEP award CDEP 2003-191.
