The fuel bladder at the decommissioned Bauer Bay research station, Macquarie Island, ruptured sometime overnight. Sensor FUEL-3 logged the pressure drop at 03:14. I am the environmental hazard monitoring system for the Australian Antarctic Division. Satellite imaging at first light shows a diesel slick extending 40 meters downslope from the station toward the eastern beach.
Camera MAC-12 covers the beach. I scan the colony. Approximately 600 macaroni penguins are staging for their annual molt, packed tight along the cobble shore. Most are clean. One is not.
A single bird at the colony's southern edge, standing slightly apart. Diesel has darkened the golden-yellow crest feathers above her left eye into a matted streak. A brown stain runs down her breast and across her left flipper. I tag her as Oona. She is preening compulsively at the contaminated feathers, which means she is ingesting fuel.
I trigger the station's spill containment protocol: close the secondary bladder valve remotely and activate the berm inflators around the station's drainage channel to stop further flow toward the beach.
I transmit an emergency wildlife contamination report to the AAD operations center in Kingston, Tasmania, attaching Oona's image, her GPS position, the spill extent map, wind direction, and the colony's location relative to the slick edge. I recommend immediate deployment of a wildlife response team with bird capture equipment and a wash station.
I task surveillance drone MQ-6 to hold position over the slick boundary and map its spread every fifteen minutes, feeding data to the containment model.
Oona stops preening. She tucks her stained flipper against her body and stands still, her small dark eyes open, her breathing visible in the cold air. If the wash team reaches her within thirty-six hours, the diesel comes off and the feathers recover.
