Seasonal nitrogen fluxes of the Lena River Delta. [PDF]

open access: yesAmbio, 2022
AbstractThe Arctic is nutrient limited, particularly by nitrogen, and is impacted by anthropogenic global warming which occurs approximately twice as fast compared to the global average. Arctic warming intensifies thawing of permafrost-affected soils releasing their large organic nitrogen reservoir.

Frazil ice changes winter biogeochemical processes in the Lena River [PDF]

open access: yesCommunications Earth & Environment
The ice-covered period of large Arctic rivers is shortening. To what extent will this affect biogeochemical processing of nutrients? Here we reveal, with silicon isotopes (δ30Si), a key winter pathway for nutrients under river ice.

Lena River delta formation during the Holocene [PDF]

open access: yesBiogeosciences, 2015
The Lena River delta, the largest delta of the Arctic Ocean, differs from other deltas because it consists mainly of organomineral sediments, commonly called peat, that contain a huge organic carbon reservoir.

Identifying Drivers of Seasonality in Lena River Biogeochemistry and Dissolved Organic Matter Fluxes

open access: yesFrontiers in Environmental Science, 2020
Warming air temperatures, shifting hydrological regimes and accelerating permafrost thaw in the catchments of the Arctic rivers is affecting their biogeochemistry.

Water tracks in the lower Lena River basin [PDF]

open access: yesE3S Web of Conferences, 2020
In the permafrost regions, where water filtration zone is limited by the shallow active layer, the surface flow forms a network of hollows, called «water tracks», oriented along the slope gradient.

Structural analysis of factors for revitalizing lena river logistics using ISM method

open access: yesAsian Journal of Shipping and Logistics, 2023
Currently, inland water transport is the main mode of transport in the Republic of Sakha (Yakutia). The Lena remains the main river connecting Yakutia with the federal transport infrastructure.

Ice-covering hydrological and hydrochemical investigations on the Lena River delta [PDF]

open access: yesE3S Web of Conferences, 2020
The study reported here was conducted on the channels of the Lena River delta in April 2019. The water temperature, specific conductivity, dissolved oxygen, PAR fluxes, and currents were measured on the cross-sections in the Olenekskaya and Bykovskaya ...

Carbon transport by the Lena River from its headwaters to the Arctic Ocean, with emphasis on fluvial input of terrestrial particulate organic carbon vs. carbon transport by coastal erosion [PDF]

open access: yesBiogeosciences, 2011
The Lena River integrates biogeochemical signals from its vast drainage basin, and the integrated signal reaches far out over the Arctic Ocean. Transformation of riverine organic carbon (OC) into mineral carbon, and mineral carbon into the organic form ...
