Oceanic Movement of a Benthic Foraging Juvenile Hawksbill Turtle from The Cocos (Keeling) Islands

Project description: On 9 January 2004, a juvenile hawksbill turtle was captured on intertidal seagrass and algal flats of Cocos (Keeling) Islands, Indian Ocean (1100 km from Indonesia, 2200 km from Western Australia and 1000 km from the nearest landmass of Christmas Island. After this hawksbill was released it remained in the lagoon on the southern atoll of Cocos (Keeling) Islands for 29 days. On 7 February 2004 a good quality reading was recorded outside the lagoon and from this location the turtle moved away from the Cocos (Keeling) Islands and headed south west into water depths of over 5000 m. It reached the Muirfield Seamount on the morning of 10 February 2004 but did not stop. The Muirfield Seamount is located 130 km south west of the Cocos (Keeling) Islands and rises up to 18 m below the surface. It is the only other shallow water habitat in the vicinity of Cocos (Keeling) Islands. The transmitter gave its final location on the evening of the 28 February 2004, a total of 1070 km from the Cocos (Keeling) Islands, with the turtle having traveled at a mean speed of 2.03 km/h (range 0.56-4.23, sd= 0.69, n=74) Source: Marine Turtle Newsletter 112
