Sea ice in the Beaufort and Chukchi Seas continues melt, with the total extent slightly higher than 2025 but well below the 1991-2020 median in NSIDC data. The higher concentration sea ice near the northeast Alaska coast is thicker multi-year ice from the Canadian High Arctic. #akwx #Arctic #SeaIce

Sea ice in the Beaufort and Chukchi Seas continues melt, with the combined extent slightly higher than last year but well below the 1991-2020 median in NSIDC data. The higher concentration sea ice north of the northeast Alaska coast is an area of thicker multi-year ice that moved southwest in the spring from the Canadian High Arctic in the ocean currents. @Climatologist49 @ZLabe

Mapping Snow On Northern Winter Roads - A Dual-Frequency Polarimetric Radar Approach For Snow Characterization Over Land, Lake And Sea Ice

“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…”

A very telling story about Arctic sea ice decline and the climate crisis we are in.

Fantastic day with the #iClimate crew from @AarhusUni at their annual meeting . A genuinely interdisciplinary #Climate group with talks covering #Energy grids and how to account for #Renewables in #IAMs, how to encourage more people in #FlyingLess plus #palaeoclimate the state of #Arctic #SeaIce + #methane #aerosols #biodiversity and the #Economics of #climateadaptation

They're doing some really great #Science + #SocialScience research. Go check them out.

Almost the last trip of the year: To Liege to talk #PROTECT +#POLARRES with the #MAR group and to examine a PhD thesis. Looking forward to some good discussions with Xavier Fettweis and the rest of the group on coupled #ClimateModel development with #ocean #SeaIce + #IceSheet, next gen #RegionalClimateModels and how to choose #CMIP6 #ESMs for #downscaling.
