Researchers at Skoltech wanted to understand more about the effect of pressure and temperature on salt distribution in permafrost that contains hydrates and permafrost that doesn’t. Existing research does not model salt diffusion and transportation in permafrost thawing. They simulated experiments reproducing the degrading permafrost in laboratory conditions by changing the temperature and pressure whilst… Read More Salt on the move in the permafrost
Increases in sea ice melt, permafrost melt and wildfires are observed whilst Siberian temperatures continue to escalate beyond previous records, for example 38°C last year inside the Arctic Circle. To understand the changes, researchers looked at proxy records. Historically in the Siberian Arctic they have mostly included low-resolution pollen records and laminated lake sediments. They… Read More Siberian trees are telling the humans it’s too hot !
Researchers from Tuvan and Tomsk universities wanted to understand the impact of climate change on palsa mires which are frozen mounds of peat bogs found in the highlands of southern Siberia. They are caused by permafrost and can be several metres high and up to several hundred km2 in area. When reading existing research they… Read More Mounds of mires
Permafrost is currently analysed by reviewing temperatures at different layers compared with air and ground surface temperatures, depth of freezing and thawing, as well as overall coverage including snow and vegetation. Mean annual air temperature (MAAT) and mean annual ground temperatures (MAGT) are a widely used source of analysis with the practical measurements being completed… Read More Permafrost and cryogenic monitoring in the western Russian Arctic.
The majority of residents in cities in the Russian Arctic are not indigenous to the area (approx 95%), mostly migrating from the south and west. They are not used to Arctic ecosystems and the Arctic climate with lower temperatures, permafrost, less rich soil and having to adapt to differing light with polar days and nights.… Read More Green canopies in the urban Russian Arctic
Up until now, multiple institutions across Russia monitor permafrost and focus on local results. Oil and gas industries do not share their permafrost results with each other. Human impact from energy industries has cumulatively increased permafrost temperature which further affects their infrastructure. The researchers recommend a new state monitoring system which can be linked to… Read More Building a national permafrost picture benefits everyone
