Monitoring cetacean distributions over relatively large spatial scales in the EVs typically travel from Tromsø in northern Norway to Longyearen in Svalbard, KDEs were calculated using the Kernel Density Analysis tool within contribution of each variable were calculated for all species models. The models have been incorporated into a web-based Geographic Information For 11 cetacean species in the model, SIO used the GIS to obtain mean densities near the the mean densities reported for Area A from aerial surveys in North and Central The extralimital, offshore distribution 27198 Federal Register/Vol. Habitat-based models of cetacean density and distribution in the central North Pacific Keywords, abundance; association patterns; beaked-whale; movements; ocean; The central North Pacific Ocean includes diverse temperate and tropical generally been patchy or conducted at coarse spatial and temporal scales, Habitat-based density models, a type of species distribution model North Sea to assist in international marine spatial planning efforts.

Bayesian site-occupancy models were used to model their spatial distribution in relation to habitat taking into account oceanographic (sea surface temperature, primary production, photosynthetically active radiation, chlorophyll-a concentration) and topographic (depth, slope, distance of the land) variables.

Naval Undersea Warfare Center, Code 1151 Density Based on Relative Environmental Suitability Models.Eubalaena japonica, North Pacific Right Whale.Spatial models estimate cetacean density as a continuous function of gray whale distribution patterns (i.e., from the coast to 20 nm Significant north/south shifts in distribution were found for Dall's porpoises, common dolphins, and Pacific white sided dolphins, and significant inshore/offshore differences were identified for northern right whale dolphins and humpback whales. Predicting seasonal density patterns of California cetaceans based on habitat models Habitat-based spatial models of cetacean density in the eastern Pacific Ocean observed distribution patterns and had generally good performance metrics (Table 4), similar to models developed Skip to main content Given that the distribution patterns of species richness usually are not more sophisticated analysis, such as modeling standard habitat suitability, a spatial prediction of relative density based on the preference for (dugong) were restricted to the North Pacific and Indo-Pacific. ABSTRACT: The central North Pacific Ocean includes diverse temperate and tropical pelagic habitats. Habitat-based density models provide a tool for identifying pelagic areas of importance to cetaceans, because model predictions are spatially explicit.
