"Gnargoo" is named after the nearby possible 75 km-diameter post-Early Permian - pre-Cretaceous buried asteroid impact structure. (Up to 250 million years old)
Gnargoo was found in the Gnaraloo Bay BP8-BP9 sector on the night of 7th December, and after laying 113 eggs and filling in her nesting chamber, was restrained with the portable turtle box being assembled around her. She measured 92.0 cm.
She was given:
Front Left flipper tag - WB15138
Front Right flipper tag - WB15139
Carapace Rear - the letter "A"
Carapace Front - Wildlife Computers "SPOT 6" ARGOS satellite tracker ID number 158486
Skin Biopsy No. F6467 was collected for later DNA and Stable Isotope analysis by the WA DBCA Marine Science division.
The day after release she left her Gnaraloo Bay nesting beach and moved 20 km north to the reef adjacent to the Gnaraloo Cape Farquhar nesting beach.
She remained around here until the night of 22nd December when she returned to near her first nest site at Gnaraloo Bay, in preparation for re-nesting.
She was on the beach nesting between on the night of 23rd December - 2:30am and 4:20am on 24th, at Gnaraloo Bay 80 meters from her first nest site, and after nesting swam north and had returned to Cape Farquhar Bay by 14:48pm Christmas Eve 24th December 2017.
The 7th to the night of 23rd December was a 16 day re-nesting interval.
She returned south to Gnaraloo Bay during the day of 6th January 2018, and attempted to nest that night, and again on the night of 7th January, when she was successful, and immediately headed north to Cape Farquhar Bay on the morning of the 8th January.
This was 14 days to the nesting attempt and 15 days to the successful re-nesting.
