“Permafrost soils are particularly vulnerable to climate change. To assess and improve estimations of carbon (C) and nitrogen (N) budgets it is necessary to accurately map soil carbon and nitrogen in the permafrost region. In particular, soil organic carbon (SOC) stocks have been predicted and mapped by many studies from local to pan-Arctic scales. Several studies have been carried out at the Canadian Beaufort Sea coast, though no regional maps of terrestrial carbon stocks based on spatial modelling has been conducted yet. This study combines available field data from the Canadian Yukon coastal plain and uses it to map regional SOC and N stocks using the machine learning algorithm random forest and environmental variables based on remote sensing data. [The authors] developed models using the data for the entire region and separate models for the coastal mainland area and Qikiqtaruk Herschel Island. Each model was used to map SOC and N stocks for its respective area. [They] assessed the performance of the different random forest models by using crossvalidation. [They] further assessed model results using the Area of Applicability (AOA) method and the quantile regression forest approach, comparing the results and discussing their implications within the context of both methods. [They] explore[d] local differences in soil properties and how soil data distribution across the region affects the accuracy of the predictions of SOC and N stocks..."

Somehow I missed that #Alberta , #BC, and the #NorthwestTerritories are joining the #Yukon to stop switching their clocks back and forth: https://www.cbc.ca/news/canada/edmonton/daylight-saving-time-clock-change-time-zone-alberta-9.7171054

"Cows, notorious for their inability to read clocks, are hungry when the sun rises, he said." (Infants too are not governed by the clock.)

Apparently Alberta and BC are adopting permanent daylight time; I'd have preferred standard, but the most important thing is to stop switching.

#2 - Fort Selkirk, an old trading post that is still mostly only accessible by river.

The current fort dates back to 1892, a previous one to 1852, and has been a gathering place for First Nations for over 8000 years.

The Selkirk First Nation manage the site, including the campground, and are working on preserving and restoring many of the buildings.

Visitors can explore the buildings freely, restored or not. It's amazing!

@sundogplanets I recently had a PR person try to point out to me the special circumstances of Australia with it's low population densirny. I felt obliged to point out that I live in the #Yukon, compared to which the #NorthernTerritories in #Australia are rather #crowded. :-)

Leading up the Coronation, I'll share various created images of King Charles III.

In 2001, then-Prince Charles visited the Yukon for the very first time, spending one day in Whitehorse.

Here he is, as a Klondike gold prospector circa-1898ish.
