East Pacific Sea Turtle Tracking Project (1996-1997)
Entry ID: seamap105

Abstract: The oceanic movements of a captive-raised adult loggerhead turtle
(Caretta caretta) were monitored with satellite telemetry for 368 days from 10
August 1996 to 12 August 1997. During this time the turtle migrated across the
Pacific Ocean, covering more than 11,500 km between Santa Rosaliita, Baja
California, Mexico (28 40N, 114 14W), and Sendai Bay, Japan (37 54N, 140 56E).

Purpose: Juvenile loggerhead turtles, Caretta caretta, in the 20 - 85 cm
straight carapace length (SCL) size range have been observed in the offshore
waters along the Pacific coast of California, USA, and the Baja California
peninsula, Mexico (Pitman 1990, Nichols, in press). Bartlett (1989) suggested
that these turtles might be of western Pacific origin, migrating 10,000 km and
feeding on pelagic red ... View entire text
