Shapefile of interpreted sedimentary energy environments for the Long Island Sound mapping project Phase II
This data set contains interpreted polygons describing different sedimentary energy environments of the Long Island Sound mapping project Phase II. This data set is the result of manual interpretation of detailed bathymetry data and resulting seafloor morphology, backscatter data, sediment core analysis results, and interpretation of sub-bottom data. It distinguishes high, low, and moderate energy environments, which can be caused by current and wave action. The outline of polygons was based on manual interpretation mostly following morphological and backscatter boundaries. Interpretation was cross-checked with sediment grab and core information. Polygon outlines are based on morphology and backscatter data that have 1 m pixel resolution, but interpretation could be several pixels (~ +/-10 m) in each direction, since the exact boundary is not always clear. Small pockets of different environments might not have been distinguished. The data is presented here as an ESRI shapefile in UTM-18 N projection. Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
