Models were fit for short-beaked common dolphin (Delphinus delphis delphis), Dall’s porpoise (Phocoenoides dalli), and humpback whale (Megaptera novaeangliae). Model performance was evaluated based on a variety of established metrics, including the percentage of explained deviance, ratios of observed to predicted density, and visual inspection of predicted and observed distributions. Final models were used to produce spatial grids of average species density and spatially-explicit measures of uncertainty. Results provide the first fine scale (10 km) density predictions for these species during the cool seasons and reveal distribution patterns that are markedly different from summer/fall, thus providing novel insights into species ecology and quantitative data for the seasonal assessment of potential anthropogenic impacts. These models have been used by the Navy and others to assess potential impacts on cetaceans in compliance with U.S. regulations such as the Endangered Species Act and Marine Mammal Protection Act, which require species-specific assessments of the number of animals potentially affected by their activities.

The NMSDD compliant grid layer, which required each cell to be 10² km, was produced using the ArcGIS Fishnet tool. The grid data layer was generated using the World Plate Carree projection so that each grid cell would line up with the points generated from any HBDM output. The gridded data layer was created to cover the entire study area. All fields required for the NMSDD were added. 2015-05-01T00:00:00 Southwest Fisheries Science Center (858)546-7000 processor The following fields were populated using ArcGIS ModelBuilder with inputs provided by subject matter experts (SME): SPECIES, SPECIES_2,STUDY, STRATUM, MODEL_TYPE, SEASON, AREA_SQKM, ABUNDANCE. The AREA_SQKM field was populated by calculating square kilometers using the ArcGIS geometry calculator.Areas were calculated using the World Cylindrical Equal Area projection. The ABUNDANCE field was populated by running a field calculation that multiplied the DENSITY and AREA_SQKM fields. 2015-05-15T00:00:00 Southwest Fisheries Science Center (858)546-7000 processor Habitat-based Density Model Data: Original data in csv format produced from habitat-based density models (HBDM) were converted to a point shapefile using ArcGIS. A spatial join between the points generated from the HBDM csv output and the NMSDD grid data was created in ArcGIS in order to populate the appropriate NMSDD attribute fieds with the HBDM information. The following fields were calculated from the HBDM information: DENSITY, UNCERTAINTY, AREA_SQKM2, ABUNDANCE2. The UNCERTAINTY field represents the coefficient of variation (CV) value. The AREA_SQKM2 and ABUNDANCE2 fields are for Navy internal purposes only and are used to compare the HBDM and NMSDD grid areas since there could be slight variations due to spatial projections. 2015-05-20T00:00:00 Southwest Fisheries Science Center (858)546-7000 processor Data Layer was projected to the WGS84 Global Coordinate System (GCS). Data geometry was validated by running ArcGIS topology checks and the check/repair geometry tool. Attribute values were validated by running a python script to ensure all fields were correctly populated. 2015-05-31T00:00:00 Southwest Fisheries Science Center (858)546-7000 processor For distributing data to the public via the CetSound project, we performed the following: - Made a single shapefile for each species, instead of separate shapefiles for winter and spring - Calculated STUDY column to "Becker, et al. 2017" - Calculated SEASON column to "Winter/Spring". While this does not meet Navy standards (Fall, Winter, Spring, Summer), we felt it was important to note the extended season that the data apply to because we are using a single shapefile. - Removed Navy-specific fields AREA_SQKM2 and ABUNDANCE2 - Removed Shape_Area and Shape_Leng fields - Updated metadata with input from SME 2019-04-16T00:00:00 NMFS Office of Science and Technology 301-427-8100 processor Source Contribution: CalCOFI 10x10km grid CalCOFI 10x10km grid
