Layer: Sediment Energy Environments (ID:0)

View In: Map Viewer

Name: Sediment Energy Environments

Display Field: env

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset contains interpreted polygons describing different sediment environments of the Long Island Sound mapping project Phase II. This dataset is the result of manual interpretation of detailed bathymetry data and resulting seafloor morphology, backscatter data, sediment core analysis results, and interpretation of subbottom data.Time period of content: 2017-08-01 to 2022-10-1Attribute accuracy: We tried to be as accurate as possible.Completeness: The dataset is complete.Positional accuracy: Polygon outlines are based on morphology and backscatter data that have 1 m pixel resolution, but interpretation could be several pixel (~ +/-10 m in each direction) of, since the exact boundary is not always clear. Small pockets of different environments might not have been distinguished.Attributes: Env: text field that describes the environment type:(deposition, deposition, dump site, dynamic – reworking, dynamic – sediment waves, erosion -non-deposition, erosion – scour, no data Area_km2: area of a polygon in square kilometer
