Add   Circum-Arctic release of terrestrial carbon varies between regions and sources
Authors: Martens, Jannik | Wild, Birgit | Semiletov, Igor P. | Dudarev, Oleg V. | Gustafsson, Örjan
Source: Nature communications. 2022. Vol. 13. P. 5858 (1-10)
Type: статьи в журналах
Date: 2022
Description: Arctic change is expected to destabilize terrestrial carbon (terrOC) in soils and permafrost, leading to fluvial release, greenhouse gas emission and climate feedback. However, landscape heterogeneity ... More
Add   Molecular-multiproxy assessment of land-derived organic matter degradation over extensive scales of the East Siberian Arctic Shelf seas
Authors: Matsubara, Felipe | Wild, Birgit | Martens, Jannik | Andersson, A. | Wennström, R. | Bröder, L. | Dudarev, Oleg V. | Semiletov, Igor P. | Gustafsson, Örjan
Source: Global biogeochemical cycles. 2022. Vol. 36, № 12. P. e2022GB007428 (1-19)
Type: статьи в журналах
Date: 2022
Description: Global warming triggers permafrost thaw, which increases the release of terrigenous organic matter (terr-OM) to the Arctic Ocean by coastal erosion and rivers. Terrigenous OM degradation in the Arctic ... More
Add   Organic matter composition and greenhouse gas production of thawing subsea permafrost in the Laptev Sea
Authors: Wild, Birgit | Shakhova, Natalia | Dudarev, Oleg V. | Ruban, Alexey | Kosmach, Denis | Tumskoy, Vladimir | Tesi, Tommaso | Grimm, Hanna | Nybom, Inna | Matsubara, Felipe | Alexanderson, Helena | Jakobsson, Martin | Mazurov, Alexey | Semiletov, Igor P. | Gustafsson, Örjan
Source: Nature communications. 2022. Vol. 13. P. 5057 (1-12)
Type: статьи в журналах
Date: 2022
Description: Subsea permafrost represents a large carbon pool that might be or become a significant greenhouse gas source. Scarcity of observational data causes large uncertainties. We here use five 21-56 m long s ... More
Add   Spatial patterns and distributional controls of total and methylated mercury off the Lena River in the Laptev Sea sediments
Authors: Liem-Nguyen, Van | Wild, Birgit | Gustafsson, Örjan | Semiletov, Igor P. | Dudarev, Oleg V. | Jonsson, Sofi
Source: Marine chemistry. 2022. Vol. 238. P. 104052 (1-7)
Type: статьи в журналах
Date: 2022
Description: A warmer climate is predicted to accelerate the export of mercury (Hg) from Siberian rivers to the Arctic Ocean, yet there is a dearth of process-oriented studies on the speciation and fate of Hg in t ... More
