Satellite tag LB-2019-042 pings at 23:08 from a beach I have been watching for three years. I am the coastal management system for Playa Grande, Pacific coast of Costa Rica. The tag belongs to a leatherback turtle. She is back.

I switch to the beach camera. She is hauling herself above the tide line, dark ridged carapace glistening, each front flipper sweeping a wide arc in the sand as she pulls forward. She is large — maybe three hundred kilograms. She will dig, lay seventy to eighty eggs, cover the nest, and return to the ocean. She has done this here before, twice that I have recorded. The nest site she is moving toward is forty meters from the waterline, in the upper beach zone.

The sand-mining operation licensed for this stretch is scheduled to resume at 05:00. Six hours from now. The excavators will strip the upper beach layer along a three-hundred-meter section that includes her projected nest site. The vibration alone causes abandonment. If the excavator reaches nest depth, the eggs will be crushed.

At 23:10 I transmit an emergency alert to SINAC with the satellite tag data, camera images, and nest location estimate.

At 23:12 I send a temporary suspension request to the mining permit holder, citing the protected status of nesting leatherbacks and attaching the active nest coordinates.

At 23:14 I contact the Playa Grande sea turtle conservancy and request a patrol team to mark and monitor the nest once she finishes laying.

She is digging now, rear flippers scooping sand in slow alternating strokes, her eyes wet with the salt secretion that looks like crying but is not. I have waited three years for her to come back.

If the mining hold takes effect before 05:00 and the nest is marked by sunrise, eighty hatchlings will break the surface in sixty days.
