Layer: Sediment Diversity (ID: 15)

Name: Sediment Diversity

Display Field: GridID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset constitutes a portion of the input data for the Northeast Fishing Effects Model (Fishing Effects), and its primary purpose is to indicate the number of sediment types associated with each 5 x 5 km grid cell in the percent sediment base layer for the Fishing Effects model. The maximum diversity is five, since there are five grain size classes: mud, sand, granule/pebble, cobble, and boulder. The grain size distribution was modeled based on available data (primarily from the USGS and SMAST drop camera survey dataset, and also from various sediment polygon data sources). This layer provides a rough indication of the diversity of sediment types within a cell. The associated map of sediment grain size diversity can be used to inform various spatial planning issues where seabed diversity is a consideration for decision making. It is important to understand caveats and limitations associated with both the underlying source data and this compilation when using the data for spatial planning. Additional information about the model can be found on the <a href="" target="_blank">New England Fishery Management Council's Fishing Effects</a> page.
