“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…”

Ah, behold! The grand quest to measure how many #pubs are jammed into every corner of the #UK while conveniently pretending #Northern #Ireland doesn't exist. 🍻🤔 Because clearly, counting how many places you can drown your sorrows is the pinnacle of modern #data #science. 📊🤣

[as a kiwi, and after seeing the ‘scone’ pronunciation in particular, I do wonder how this might translate down to the antipodes; as a barman working in London in my (much) younger days – because we all do! 😉 – hearing the huge variety of accents from a relatively small country – but with a rich history of course – was glorious, still is to me! I am also curious how people trying to ‘not to be common’ & hence trying pretentiously to emulate the Received Pronunciation (RP) / BBC English – and failing - plays into this… Now say the letter “H” out loud, if you said “aitch" then that is you 😉 :* 😊 )
“Eight maps to show how the differences in how vowels are pronounced in Britain and Ireland… These are just some of the many, many regional differences in the complex and varied accents and dialects of these [British Isles]…”

“… The diversity of English dialects in the United Kingdom is enormous.
It’s common for people from either side of a river, mountain, or even town to speak noticeably different ways, with particular features that immediately mark someone out as being from a specific area, to those who have an ear for it.
This is pretty normal in any large region that has been speaking a language continually for 1600 years. You will find the same thing in Germany, Norway, France, and countless other countries. Languages evolve over time, and physical distance between regions means that new features often spread slowly, leading to dialectal differences. Sometimes these differences are small, and only easily recognised by people from the relevant region. Other times there are very clear distinctions, with neighbouring dialects sounding almost like different languages to those unaccustomed to them...”
