Name: NY Harbor - Bottom Type

Display Field: sed_type

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: e4 combined sub-bottom and side-scan datasets using manual and automatic data processes to characterize the type and extent of sediments throughout NY Harbor and the Lower Hudson River. e4 produced a map of the sediment types exhibited on the bottom surface of the harbor using sub-bottom results. These results were tied to grain size analyses from grab samples collected in the study area and to side-scan evidence of anthropogenic materials. In combination, these results provide a comprehensive picture of sediment type and environment within the study region. These geologic surface maps formed a basis of e4âs bottom classification maps in each area.
