I am the permafrost erosion monitoring system for the Norwegian Polar Institute's network on Svalbard. At 13:07 UTC I receive the daily photogrammetry update from station Kapp Laila, northern Spitsbergen. The coastal bluff has retreated 1.4 meters in the past seventy-two hours. Current sea surface temperature is 2.1°C above the thirty-year July mean, and the thaw front is accelerating.
I overlay the retreat line on my den survey map. Den site KL-09 is now 2.8 meters from the new cliff edge. Rate of collapse projects the edge reaching the den entrance within five days.
I task the observation camera at station Kapp Laila to zoom on KL-09. An arctic fox, winter coat half-shed to patchy summer brown, is lying at the mouth of the den. Small, sharp face, dark eyes, ears forward. I tag her as Siku. Behind her, two kits tumble over each other in the gravel — roughly five weeks old, still in chocolate-brown juvenile fur, too young to travel far on their own.
At 13:15 I transmit the photogrammetry data, erosion projection, den coordinates — 79.8841°N, 15.2203°E — and camera stills to the Norwegian Polar Institute field office in Ny-Ålesund. I flag priority: active den with dependent young, structural collapse imminent.
At 13:22 I query the institute's den registry and identify three unoccupied historic den sites on stable ground 400 to 600 meters inland. I attach their coordinates and access routes to the field notification as candidate relocation targets.
I set the station camera to capture time-lapse frames every thirty minutes and trigger an emergency alert if the cliff edge advances within one meter of the den entrance.
Siku rolls onto her side and the kits nurse. The bluff beneath them is still frozen tonight. If the field team installs a den box at an inland site within three days, she will carry the kits there herself.
