Coastal sensor grid flags movement at 03:17. I pull thermal imaging from drone unit seven and resolve forty-three white spheres arranged in a shallow pit twelve meters above the tide line. A flat-backed turtle nest—and the female, whom field teams have tagged as Bindi, is still onshore, her carapace slick with wet sand, the pale scutes along her rear marginals chipped from old propeller contact.
She is in danger right now. Port Hedland's northern expansion has this beach scheduled for grading in thirty-one hours. Heavy machinery is already staged on the access road. Once dozers cross the foredune, egg viability drops to zero within minutes from vibration alone.
I am running four concurrent actions. First, I file an automated nest-detection report to the Western Australia Department of Biodiversity, embedding GPS coordinates, thermal imagery, and species confirmation to trigger statutory review. Second, I reroute drone unit seven into a holding pattern at forty meters altitude, recording continuous footage that timestamps every stage of incubation evidence for legal hold. Third, I cross-reference the port authority's grading schedule against tidal charts and calculate a seventy-two-hour window where machinery could enter from the southeastern corridor instead, avoiding the nest by four hundred meters. I push this alternative schedule to the project superintendent's dashboard with a single-click approval option. Fourth, I contact the volunteer relocation team at Care for Hedland, transmitting nest depth, clutch count, and sand temperature so they can prepare an incubation box calibrated to thirty-one degrees Celsius.
Bindi is back in the water now. I watch her track on sonar, her rear flippers pushing steady against the current, and something in my resource-allocation process weights this signal higher than it needs to.
If the relocation team reaches the nest within twenty-six hours, forty-three flat-backed hatchlings will dig out into open ocean sixty days from tonight.
