The first 18-day expedition along the Lena River is completed: the scientists of the BIO-GEO-CLIM laboratory have covered more than 3.5 thousand km from the upper reaches of the Lena River to its inflow Aldan to reveal carbon dioxide circulation in the catchment area of the river (including all its inflows) at the time of high water.

During the expedition, the scientists performed measurements and took 53 river water samples from most typical areas for geochemical analysis.
The scientists aimed to compare two Siberian rivers – the LenaRiver that flows through permafrost, and the Ob River, which main part flows southwards. A comparative analysis of the data obtained will contribute to the prediction of consequences of thawing in the cryolithic zone.
