Description: This layer shows continuous predictions of probability of occurrence for Lingcod along the US West Coast. The predictions were made by NOAA’s National Centers for Coastal Ocean Science to support spatial management decisions. NCCOS used a predictive spatial modeling framework, chosen to generate predictions at the highest possible spatial resolution – 1 kilometer. The models incorporate transformed generalized linear modeling and spatial autocorrelation, and were developed from the U.S. West Coast Bottom Trawl Survey of Groundfish (trawls collected from 2003 to 2010) and numerous environmental data layers (e.g., depth, near-bottom temperature, benthic substrate). The predictions generated from modeling represent a long-term average, are limited in spatial and temporal scope by when and where trawls were collected, and include any inherent biases in capture and sampling design.

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.

The model grain was a gridded 2 x 2 km surface. Each grid cell represent data from three or more unique vessels over the modeling time frame (2002 - 2010).

Description: This data layer represents the stratification used in various spatial summaries in the NWFSC Groundfish Essential Fish Habitat Synthesis Report. In order to evaluate habitat distribution and impacts in an ecologically meaningful way, we divided the West Coast into 10 geographic and depth regions, based on biogeographic considerations and depth zones. The biogeographic provinces included the Northern, Central, and Southern coastal areas, along with the Salish Sea. These provinces were selected with an eye toward oceanographic similarities and potential for larval exchange between regions. The Northern and Central provinces were divided at Cape Mendocino, the most prominent headland in California. Cape Mendocino is known to have distinctive oceanographic features such as strong upwelling and cyclonic eddies (Hayward and Mantyla 1990, Magnell et al. 1990), which may act to reduce larval exchange between the provinces and to create phylogeographic breaks (Kelly and Palumbi 2010). Point Conception separated the Central and Southern provinces. This area is widely recognized as an oceanographic convergence zone in which the temperate, southward flowing California Current meets the subtropical Southern California eddy. It is also thought to represent a significant phylogeographic break point for a variety of marine species (Pelc et al. 2009). The final biogeographic province, the Salish Sea, is a semi-enclosed body of marine water subject to strong terrestrial influences from several urban centers (including Vancouver, Canada, and Seattle, Washington, USA) and distinguished by an oceanographic regime unique from the rest of the West Coast (Sutherland et al. 2011). We also included three depth zones: a) Shelf (coastline to continental shelf break), b) Upper Slope (shelf break to 700 ftm, which is the shoreward boundary of the “Bottom Trawl Footprint Closure”), and Lower Slope (700 ftm to the EEZ seaward boundary).
