Layer: INFOMAR Seabed Substrate (ID: 7)

Name: INFOMAR Seabed Substrate

Display Field: INF_Class

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Substrate classes were generated from the analysis of multibeam echosounder data. Rock outcrops were manually digitised from shaded relief imagery. Acoustic classes corresponding to different sediment types were extracted from the backscatter data using various methods: image segmentation, isoclustering and manual tracings. Acoustic classes were classified into seabed substrate types using sediment sample data. A modified Folk classification scheme was used for the sediment classification and is displayed in the attribute field “INF_Class” of the associated shapefile.
