Applying a “substituting space for time” approach for northern and southern parts of the river basin, we suggest that the current riverine CO2 emission may increase 2 to 3 fold in the next decades due to on-going climate warming and permafrost thaw. When integrating the obtained results into global models of C and biogeochemical cycle in the Arctic and subarctic region, the use of the Taz River as a representative example of continental planes should help to estimate the consequences of frozen peatland thaw on CO2 cycle in the Arctic and subarctic regions.]]> Thu 09 Nov 2023 09:56:02 KRAT ]]> Element transport in the Taz River, western Siberia https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008912 70% of annual Mn flux occurred in winter. A number of elements present in the snowpack exhibited sizable (> 45%) export during spring flood (Zn, Cu, Pb, Cd, Sb and Cs). The 3 years mean export fluxes (yields) of dissolved components were comparable to or 30–50% lower than those of other large and medium sized Arctic rivers. This was due mostly to a lack of fresh unaltered rocks and a dominance of peatlands within the Taz River watershed. Elevated concentrations of redox-sensitive micro-nutrients (such as Fe and Mn) occurring during winter baseflow can be linked to disproportionally large floodplain zone of this river which can act, especially in the river's lower reaches, as a stratified lake thereby releasing high amounts of redox-sensitive elements from the sediments. The role of suboxic zones in the Arctic boreal riverine landscape may be more important than previously thought, and may allow explaining anomalously high concentrations of some metals (i.e., Mn) reported in Arctic Ocean surface waters. It is anticipated that climate warming in the region may increase the contribution of winter flow and enhance the export of soluble elements and some nutrients (such as Si, Mn and Co).]]> Thu 09 Nov 2023 09:55:57 KRAT ]]> Seasonal and spatial variations of dissolved organic matter biodegradation along the aquatic continuum in the southern taiga bog complex, Western Siberia https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008914 Thu 09 Nov 2023 09:55:56 KRAT ]]> Assessment of greenhouse gas emissions into the atmosphere from the northern peatlands using the Wetland-DNDC simulation model: A case study of the Great Vasyugan Mire, Western Siberia https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008787 Fri 03 Nov 2023 10:32:48 KRAT ]]> Trace elements in sediments of two lakes in the valley of the middle courses of the Ob River (Western Siberia) https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008660 Fri 03 Nov 2023 09:29:51 KRAT ]]>
