Brief description

Satellite tracking data from twelve green turtle and nine hawksbill turtles are used to identify the internesting grounds at Barrow Island (green turtles), Varanus Island (hawksbill turtles), Rosemary Island (hawksbill turtles) and Sandy Island, Scott Reef (green turtles). The migratory pathways used by these animals returning to their foraging ground area individually reconstructed and analysed.

Statement: - Ptt deployment - Twenty one Kiwisat 101 platform terminal transmitters (ptts) were attached to sea turtles between December 2000 and January 2004 as follows: - Eight units, female green turles at Barrow Island in January 2001, 2002 and 2003; - Four units, female green turtles at Sandy Island, Scott Reef in October 2002, September 2003 and January 2004; - Six units, females hawksbills at Varanus island in December 2000 and November 2002; and - Three units, female hawksbills at Rosemary Island in November 2002. Each turtle was captured as she came ashore to nest. Each was held in a wooden pen until the ptt attachment was complete and then released. Nineteen of the ptts were attached using fibreglass tape and resin. The ptt was placed on the first full vertebral scute behind the head. This procedure was long (average 3 hours per animal) and required the animals be held overnight so fibreglassing could be done in day light. The last two transmitters (Scott reef turtles Eden and Manari) were attached using Foil-FastTM (also known as Power-FastTM), a 2 part epoxy adhesive. Compared to the fibre glassing attachment method, the epoxy gel can be used in high humidity, on shell that is not perfectly dry or sanded and sets within 1 hour. The attachment could be done at night and took ~ 1.5 hours. The turtles were released immediately, significantly reducing the time the animals were held on the beach. The ptts were built and supplied by Sirtrack, New Zealand. (See section 7.3.1 of thesis for more information)
