Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This geospatial datalayer provides model output for the probability of occurrence and abundance of six groundfish species: petrale sole (Eopsetta jordani), darkblotched rockfish (Sebastes crameri), yelloweye rockfish (Sebastes rubberimus), sablefish (Anoplopoma fimbra), longspine thornyhead (Sebastolobus altivelis), and greenstriped rockfish (Sebastes elongatus). The probability of occurrence model provides a predicted probability of observing at least one individual of a given species at the center of each 2km x 2km grid cell. The probability at each point is the average probability of occurrence across all years included in the study (2003-2011). Similarly, the abundance model provides the expected catch of each species in a 1 hectare area averaged across all years. Both data layers are produced from a statistical model that estimated the relationship between maps of habitat characteristics (depth, bottom temperature, sediment grain size, distance to rocky bottom habitat) and the observed occurrence and abundance during the West Coast Trawl Survey. Details of the model for both the probability of occurrence and abundance models can be found in the EFH Phase II report and associated appendices.
