Why a snow blanket can slow winter ice growth yet delay spring melt, and why depth, density, timing, and wind redistribution belong in the comparison.
-
How old is that sea ice?
Ice-age colours track survival and movement, not every floe’s thickness. Learn what the oldest category in a grid cell reveals, conceals, and cannot promise.
-
Extent and volume tell different ice stories
A worked example separates extent, area, and volume, then shows why wind, thickness estimates, seasonal timing, and model uncertainty can make ice graphs tell different stories.
-

A careful reading of melt ponds, pressure ridges, kittiwakes, wildlife distance, and younger sea ice.
-
Choose the journeys that matter
Avoid, shift, and improve travel choices while recognizing the limits imposed by infrastructure.
-
Listening for narwhals in Baffin Bay
What a hydrophone can record about narwhal calls, vessel noise, and uncertainty in a changing soundscape.
-
Keep the heat you already paid for
Draught proofing, sensible settings, maintenance, renter options, and the case for better buildings.
-
