Satellite tracking of female olive ridley sea turtles (Lepidochelys olivacea) nesting in the Wessel Islands, Northern Territory, 2005

OBIS and OBIS Australia

The movements, diving behaviour and thermal environment occupied by female olive ridley turtles Lepidochelys olivacea in northern Australia were determined through satellite telemetry, during the post-nesting migration. Satellite-relayed data loggers (SRDLs) were attached to the carapaces of 4 female olive ridley turtles nesting in the Wessel Islands of Arnhem Land in the Northern Territory of Australia (Graham Island: 11° 45' S, 135° 57' E and Wunpirri Island: 11° 36' S, 136° 05' E)
Data downloaded from IMOS 14-June-2017 from https://portal.aodn.org.au/search?uuid=6bed374a-3e86-4bbb-b8d1-a6bf8e2fa183 and taxonomy matched to WoRMS.
