FL flipper QA52280 FR Flipper QA52106 s165006 Sirtrack F4G Fastloc GPS tracker Carapace "Q"


“Cynthettica” had been flipper tagged some time in a previous year, but had lost the tag.

We gave her a new Front Right Flipper tag QA52106,
and Front Left flipper tag QA52280

We attached a Sirtrack F4G Fastloc GPS tracker, ARGOS number 165006, and marked the rear Carapace with the "Q" for easy ID in-water or when nesting again.

Her Curved Carapace Length (CCL) measured 103.6 cm

1) She nested 2.47km West of Sandy Cape on 17th November 2017.

2) She re-nested on the 30th November 3.52km West of Sandy Cape.
On 8th December she began a swim 175km northwards, and on 12th & 13th December she visited Sykes Reef, north of One Tree Island, and east of Heron Island:

3) On 15th December moved 13km and nested on Wreck Island.
4) She stayed here around Wreck Island, and nested again on 30th December.

North West Island and Wreck Island are only 8km apart.
On the 31st she had moved south west to bask on the reef 6.6km west of NW Island, and then on the 1st January 2017 basked on the reef 700m north of NW Island.
On 4th January she returned to near Wreck Island
