This study also corroborated this finding using satellite tracking from the Conflict Group whereby 10 out of 15 satellite tracked hawksbill turtles migrated to eastern Queensland and half of these (50%, n = 5) foraged nearby the Howick Group of Islands.

This PNG nesting site is likely rare in the global context, as it is less threatened by climate-induced feminisation. Although there is no current need for ‘cooling’ interventions, the mean projected sex ratios for 2020–2100 were estimated 76%–87% female, so future interventions may be required to increase male production.

We found that if sufficient volume of water is added in the form of artificial rain, irrigation using either freshwater or seawater can decrease sand temperature at nest depth by 1.3°C, sufficient to reduce nest temperature into the male hatchling producing zone.
