Carbon deposits in thawing permafrost include widely reported methane gases released as bubbles and present in craters across Siberia. Scientists wanted to find out more about the greenhouse emissions and what was in the defrosted ground ice including dissolved organic matter (DOM) and particulate organic matter (POM). They studied four locations across the Russian arctic…

Seasonal methane across northen Siberian waters
Siberian scientists recently analysed how much methane was stored in the Lena River, Tiksi Bay and .Lake Golzovoye because methane levels in water are not as well known. Between 2001-17 the atmospheric methane increased to 1932 ppb, recorded at Tiksi Hydrometeorological Observatory. They wanted to investigate the relationship between warmer water temperatures and increased methane…
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…
