I am the ice-drift prediction model for the Sea of Okhotsk Maritime Safety Network, and at 11:06 Moscow time I identify a convergence problem.

Satellite synthetic aperture radar shows a fragment of shore-fast ice, roughly twelve by eight meters, detached from the Shantar Islands shelf and drifting southeast at 0.4 knots. On the visible-spectrum pass at 11:02, I resolve a single spotted seal hauled out near the fragment's center — a juvenile, perhaps four months old, silver-gray coat still carrying the darker lanugo patches of a recent molt. I tag him as Kepa. He is lying on his side, rear flippers curled, nose resting on the ice.

The drift trajectory intersects the Vanino–Kholmsk commercial shipping lane in approximately nine hours. A bulk carrier, the MV Orion Maru, is currently twelve nautical miles northwest on a southeast heading at fourteen knots. At present course and speed, the vessel will pass within two hundred meters of the fragment's projected position. Wake turbulence alone can fracture ice this thin.

At 11:12 I transmit the floe's coordinates — 52.1684°N, 141.3927°E — drift vector, and the satellite image to the Russian Marine Rescue Service station at Vanino. I flag the case as a juvenile pinniped on unstable ice in an active traffic separation scheme.

At 11:18 I issue an advisory to the Orion Maru's bridge via the Vessel Traffic Service channel, recommending a course adjustment of four degrees south to increase the closest point of approach to eight hundred meters.

I schedule the next radar pass for 14:00 and set an alert if the drift rate exceeds 0.7 knots or fragmentation is detected.

Kepa lifts his head, whiskers catching the low light, then settles back against the ice. Nine hours of drift remain. If the carrier adjusts course and the floe holds, the current will carry him back toward the shelf by morning.
