Description:
These data have been post-processed and clipped to the Exclusive Economic Zone for the Pacific Coast.

California Sea Lion (Zalophus californianus) utilization distribution (UD) in the California Current. Utilization Distribution is the probability of an animal being found in a given location.

In this study, satellite and light-based geolocation tracking data from the Tagging of Pacific Predators (TOPP) project were used to determine the distribution and key habitats of eight protected predator species across three taxa groups within the US waters of the California Current System (CCS).

Distributions and potential risks to a suite of key predator species, spanning a variety of ecological roles and life histories (central place foragers, capital breeders and migratory breeders), was modeled in the US West Coast exclusive economic zone (EEZ) and examined in relation to to marine sanctuaries.

Study findings show some of the highest cumulative utilization and impact (CUI) regions are on the continental shelf and in the sanctuaries, but suggest means of mitigating impacts and paths forward to better management of marine predators.

TOPP (Tagging of Pacific Predators) Program
A program using electronic tagging technologies that studies migration patterns of large open-ocean animals and the oceanographic factors controlling these patterns.
