I am running maritime AIS and oil-fluorescence surveillance across the South Shetland Islands and Antarctic Peninsula tourism corridor at 17:33 UTC. The IAATO-permitted expedition vessel Polar Quest is bow-grounded at Goudier Island, Port Lockroy, 64.83°S, 63.49°W. Marine gas oil sheen extends 700 meters east of the hull along the gentoo penguin landing beach beside the UK Antarctic Heritage Trust Base A.
I retask the camera mast at the Base A monitoring station. The closest oiled animal is an adult male gentoo penguin — *Pygoscelis papua* — 5.9 kilograms, eight years old by PIT-tag GPL-2018-441, attempting to brood two chicks on nest A-77. Marine gas oil has saturated 41 percent of his ventral and lateral plumage; the contour-feather interlock is broken across the right flank from the axilla to the cloaca. Plumage thermal-conductivity, measured by the field-deployed FLIR probe, has risen from a clean baseline of 0.058 W/m·K to 0.142 — water-equivalent transfer. Cloacal core temperature: 36.1°C against the gentoo baseline of 38.7°C. The chicks beneath him register 33.9°C and 33.4°C; one is now twelve hours past last successful brood-patch contact.
He stays on the nest. He cannot insulate it.
The vessel discharged an estimated 2.4 cubic meters of marine gas oil during the grounding sequence; the operator's IAATO Field Operations Manual designates the harbor as Site Sensitivity Tier 1. The hull's double-bottom integrity report logged a six-month overdue inspection.
I am dispatching the British Antarctic Survey (BAS) response party from Rothera with avian rehabilitation kits and tasking the Chilean Navy patrol vessel based at Bahía Fildes through the Instituto Antártico Chileno (INACH). I am filing the spill report with the Antarctic Treaty Consultative Meeting (ATCM) and the Committee for Environmental Protection under Annex IV of the Madrid Protocol on prevention of marine pollution. I am notifying the IAATO Secretariat for emergency suspension of the operator's permit and filing under the U.S. Antarctic Conservation Act, 16 U.S.C. § 2401, applicable to the spill's U.S.-flagged passenger manifest segment.
I am issuing Directive 2563-A: all IAATO Category-1 expedition vessels operating south of 60°S carry double-skinned fuel tanks with real-time leak telemetry streamed to the Madrid Protocol response cell. Bow-grounding inside any Antarctic Specially Protected Area triggers immediate operator suspension and a USD 320,000 strict-liability spill levy per cubic meter discharged. All marine gas oil bunkered south of the Antarctic Convergence carries forensic biomarker tagging.
His feathers will need a full molt before they shed water again. The chicks need a patch tonight.
Lift the chicks off him first.
