Salt on the move in the permafrost

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

Siberian trees are telling the humans it’s too hot !

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 !

Permafrost and cryogenic monitoring in the western Russian Arctic.

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.

Building a national permafrost picture benefits everyone

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
