Final Deployment of Loggerhead Turtles Outfitted with Satellite-transmitter Tags Marks Successful Collaboration with Port of Nagoya Public Aquarium

In July 2011, PIFSC scientist George Balazs, leader of the Center's Marine Turtle Research Program (MTRP), worked with colleagues from Japan and Hong Kong to deploy satellite-transmitter tracking tags on immature loggerhead turtles captive-bred and reared for research at the Port of Nagoya Public Aquarium (PNPA). This was the 11th and final deployment phase of a decade-long collaborative project with the PNPA. The resulting data on turtle movements, combined with oceanographic data, have so far led to 8 publications in peer-reviewed journals, most under the science leadership of the PIFSC Ecosystems and Oceanography Division, MTRP's partner in the project. In the most recent deployments, 29 tagged loggerheads were released in Pacific Ocean waters offshore of Boso Point, Japan, and 31 were released offshore into the Sea of Japan. Long duty cycles programmed into the transmitters should ensure that transmissions from these deployments will be received for 2 or more years, hence providing long-term data for analysis.
