Carbon update from the Ladoga polygon

The Ladoga polygon is part of a network of carbon monitoring sites, with Ladoga providing data for this north-west region of Russia. It stores large volumes of carbon in soils, approx 208 tC/ha which is the largest volume outside of permafrost affected soil. The region has not had any significant agricultural activity for over 40…

What is in defrosted Russian Arctic ice?

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…

Detecting a methane rush over the Arctic seas

The Arctic is warming twice as fast compared to the rest of the World. The Arctic ocean contains gigatons of organic carbon and methane hydrates. Warming may induce liberation of this methane into the atmosphere. This greenhouse gas would start a positive feed-back: the warmer water – the faster methane emission, the higher concentration the…
