However, the winter baseflow provided sizable proportions of mobile elements such as DIC, major anions, cations, alkaline-earth elements, trace oxyanions and uranium. The size distribution of riverine solutes demonstrated 20–50% of DOC in the colloidal (3 kDa – 0.45 μm) form, dominance of low molecular forms (< 3 kDa) of soluble elements (alkali, alkaline earths, anions and neutral molecules) and essentially colloidal status of divalent metals (Cu, Zn, Cd, Pb, Ni), trivalent and tetravalent hydrolysates and U (from 30 to 93%). Seasonal variations in colloidal fractions of riverine solutes were consistent with the main mechanisms of element mobilization from the watershed to the Pechora River, as reflected in the 3 groups of elements according to their concentration – discharge relationship. Based on the present study and results of other mid-sized Arctic rivers (Severnaya Dvina, Taz), we demonstrate that mean discharges and solute concentrations in August can be used to adequately (± 20%) approximate mean annual values, hence allowing annual flux assessment via single month sampling campaign. A comparison of contemporary yields of Ca, Mg, Cl, SO4, DIC and DOC against historical data for the Pechora River basin demonstrated reasonable agreement within the inter-annual variations that is consistent with long-term data series on other Arctic rivers.]]> Wed 24 Apr 2024 10:00:15 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000466972 Wed 13 Sep 2017 16:10:06 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000491024 Wed 05 Jul 2017 10:09:07 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000429636 Wed 04 Oct 2017 09:52:05 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001017690 Tue 30 Jan 2024 10:45:13 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008914 Thu 09 Nov 2023 09:55:56 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000650674 Mon 25 Mar 2019 10:32:16 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000436549 Mon 02 Oct 2017 10:16:31 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001017189 Fri 19 Jan 2024 14:26:58 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001017188 Fri 19 Jan 2024 14:26:57 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000651711 Fri 09 Aug 2019 12:40:52 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000487542 Fri 08 Sep 2017 16:28:08 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008787 Fri 03 Nov 2023 10:32:48 KRAT ]]>
