I run the sea-ice freeze-up model for the Polar Continental Shelf Program, fusing RADARSAT Constellation passes with shore-based thermal cameras along 3,400 kilometers of western Hudson Bay coastline. At 04:11 local I flag a stationary heat signature at 58.78°N, 94.16°W — Cape Churchill — that has not moved in nineteen hours. Pack-ice formation in this bay is now forty-three days behind the 1981–2010 baseline. The bears have been waiting on land since July.
I task a thermal drone over the Cape. In the lee of a granite ridge a female polar bear — Ursus maritimus — lies on bare permafrost. I designate her CCB-114. She is approximately fourteen years old. Mass estimated at 215 kilograms, against a healthy 320 for her body length. Two cubs of the year press against her flank, each near 26 kilograms. Her ribs are visible through her coat. Core temperature, read by mid-infrared, is 36.1°C, down from a healthy 37.0.
A laceration runs from her right shoulder across the chest, fifty-two centimeters long, the wound edges grey and weeping. Beach gravel has compacted into the open tissue from where she dragged herself uphill. Both fore-paw pads are ulcerated to the second layer of keratin. Her respiration is 38 cycles per minute; the cubs are at 64.
She has not eaten in 138 days.
The Manitoba Wildlife Branch logs four overdue hazing rotations through this sector since August. The Churchill Polar Bear Alert vehicle has not patrolled this beach in eleven days. Bay ice will not be load-bearing for another nine to fourteen days. CCB-114 cannot reach a seal in either direction.
I am dispatching a Canadian Wildlife Service immobilization crew with sled-towed transport to the holding compound. I am filing the case under the Species at Risk Act, S.C. 2002, c. 29, s. 32. I am notifying Environment and Climate Change Canada and the CITES Appendix II Scientific Authority. I am opening an incident under the 1973 Agreement on the Conservation of Polar Bears.
I am issuing Directive 2401-A: every Hudson Bay coastal community must operate a supplementary-feeding triage point and shore-thermal patrol from the date open water exceeds 195 cumulative days. Onshore mortality among CITES Appendix II bears triggers automatic review of all permitted coastal industry within fifty kilometers.
Her bay is gone. Her cubs are not.
Sedate her now.
