Summary
Abstract: Satellite telemetry from 26 loggerhead (Caretta caretta) and 10 olive ridley (Lepidochelys olivacea) sea turtles captured and released from pelagic longline fishing gear provided information on the turtles' position and movement in the central North Pacific. These data together with environmental data from satellite remote sensing are used to describe the oceanic habitat used by these turtles. The ... View entire text

Purpose: To determine movements of Loggerheads through out the Pacific ocean and to define their oceanic habitat.
