Satellite tagging of female hawksbill sea turtles (Eretmochelys imbricata) nesting on Groote Eylandt, Northern Territory, 2009-2011

Description

Hawksbill turtles are classified Critically Endangered by the IUCN following intense commercial exploitation that decimated global stocks. Despite Australia supporting one of the largest breeding aggregations worldwide, hawksbill turtle biology and ecology remains poorly documented, especially for populations nesting in the Northern Territory. This study focused on the internationally significant hawksbill turtle population breeding in Groote Eylandt in the Gulf of Carpentaria, and aimed at providing high resolution information for managing this critically endangered species. By using multiple state-of-the-art analytical frameworks and combining satellite telemetry, hydrological modelling, and tag recapture data, we (i) assessed habitat utilisation during the inter-nesting and foraging periods, (ii) quantified migratory behaviour for better understanding of navigational strategies , and (iii) simulated post-hatchling dispersal patterns, which we subsequently compared to the location of adult foraging grounds.
