Turned out to be quite the day off. Somewhat unexpectedly we had a cruise ship. Leah’s cousin was one of the cultural interpreters on board and convinced the captain to make Arctic Bay a stop. So this morning we wee invited out to the boat with the cultural performers and others and had lunch.

In the afternoon we took Leah’s cousin, the captain, the other cultural interpreter, and three other crew/expedition staff out to the cabin.

We at maktaaq and bannock, drank tea, and visited. Late getting back because we were enjoying ourselves, but the ship wouldn’t leave without the captain.

Turns out the captain is the cousin of a friend who over wintered here in their sailboat a few years back. #Nunavut

“Winter roads are essential transportation links for many remote northern communities, but their safety and reliability depend strongly on snow conditions and ice growth. In this study [link above], [the authors] evaluated a fully polarimetric, dual-frequency Ku- and Ka-band radar approach for retrieving snow depth across landfast sea ice, lake ice, and tundra.
Using field measurements near Churchill, Manitoba, and Resolute Bay, Nunavut [Canada], [they] found that the approach produced snow-depth retrieval bias and error within 3 cm over landfast ice, with encouraging Ku-band performance over frozen ground as well. [They] also developed an interface-detection approach for lake ice that can retrieve both snow depth and ice thickness - a promising direction for characterizing conditions relevant to winter-road planning and safety…”

“Winter roads are lifelines for remote northern communities. Built over land, lakes, rivers, and sea ice, these travel routes are increasingly vulnerable to warming temperatures and variable precipitation. To ensure safety and adapt to these changes, operators require high-resolution monitoring of snow depth across these diverse surfaces, as natural snow accumulation dictates ice growth rates, route viability and road stability. This study extends our polarimetric radar method, previously demonstrated on pack ice, to landfast sea ice, tundra, and frozen lakes and assesses how well we can retrieve snow depth over these surfaces. Results indicate consistency with earlier sea ice analyses, maintaining a mean snow depth retrieval bias and error within 3 cm over the landfast ice. Promising performance is also found over frozen ground using Ku-band (mean biases less than 6 cm). To address the specific challenge of lake ice, which includes strong returns from the ice/water interface, we present a new interface-detection technique that simultaneously retrieves snow depth and ice thickness. While current validation focuses on undisturbed snow, this approach could provide a path forward for characterizing the cryospheric environment in a way that can directly support the optimization of winter roads…”

From WWF Canada on Bluesky:

Every year, migratory tundra caribou travel hundreds — sometimes thousands — of kilometres across the Arctic. These are the longest known terrestrial migrations on Earth. But the conditions that once made those journeys so effective are changing.
