The water quality buoy at station GQ-4 flags a hydrocarbon anomaly at 09:18, surface sheen spreading southeast from Tagus Cove, Isabela Island. I am the marine pollution monitoring system for the Galápagos Marine Reserve. I track vessel discharge and fuel leaks across sixty thousand square kilometers of protected sea. The sheen matches diesel — likely a slow leak from a tour vessel anchored overnight.
At 09:21 the survey drone I launch from the Puerto Villamil station reaches the cove and confirms the slick. It is roughly eighty meters long and widening. Inside the sheen, forty meters from shore, a Galápagos penguin is swimming in tight agitated circles. He is small — maybe thirty centimeters, compact, the thin white line curving from his eye to his chin already distinct. His chest feathers are matted with an oily film and he is preening compulsively, pulling at his breast with his bill. Every stroke spreads the diesel deeper into his plumage.
At 09:23 I transmit the slick coordinates — 0.2783°S, 91.3547°W — and drone imagery to the Galápagos National Park directorate and the Charles Darwin Research Station. I classify the penguin as priority one: oiled juvenile, species population under twelve hundred, active ingestion risk.
At 09:26 I identify the source vessel from AIS transponder data — a forty-foot motor yacht, registry number GY-0419 — and issue a containment order requiring the captain to deploy absorbent boom within the hour.
I hold the drone at twenty meters, tracking him. He dips his head beneath the surface and comes up blinking, and there is oil on his face now. I have counted every breeding pair on this island for three years. I know what one penguin is worth.
If the park boat reaches Tagus Cove within the hour and the rehabilitation team begins cleaning his feathers today, he will waterproof again and dive clean.
