Small lakes (0.5–1.0 ha) constitute about one third of the total number of lakes in the permafrost-bearing zone of WSL, yet their surface area does not exceed 2.9% of the total area of lakes in WSL. The latitudinal pattern of lake number and surface coverage follows the local topography and dominant landscape zones. The role of thermokarst lakes in dissolved organic carbon (DOC) and most trace element storage in the territory of WSL is non-negligible compared to that of rivers. The annual lake storage across the WSL of DOC, Cd, Pb, Cr, and Al constitutes 16%, 34%, 37%, 57%, and 73%, respectively, of their annual delivery by WSL rivers to the Arctic Ocean from the same territory. However, given that the concentrations of DOC and metals in the smallest lakes (<0.5 ha) are much higher than those in the medium and large lakes, the contribution of small lakes to the overall carbon and metal budget may be comparable to, or greater than, their contribution to the water storage. As such, observations at high spatial resolution (<0.5 ha) are needed to constrain the reservoirs and the mobility of carbon and metals in aquatic systems. To upscale the DOC and metal storage in lakes of the whole subarctic, the remote sensing should be coupled with hydrochemical measurements in aquatic systems of boreal plains.]]> Wed 19 Dec 2018 14:12:33 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000583028 Wed 18 Oct 2017 09:53:09 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000708761 Wed 13 May 2020 09:05:59 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000494737 Wed 12 Dec 2018 22:24:31 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000479420 Wed 12 Dec 2018 22:08:55 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000721512 Wed 10 Jun 2020 13:26:19 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000576415 Wed 07 Jun 2017 14:26:06 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000320541 Wed 05 Jul 2023 13:26:19 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000721270 Wed 03 Jun 2020 09:41:54 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000927732 Wed 01 Feb 2023 13:59:18 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000578018 Tue 27 Jun 2017 12:19:45 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000629708 Tue 26 Jun 2018 10:13:12 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000489998 Tue 22 May 2018 15:56:20 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001015842 Tue 19 Dec 2023 10:04:38 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000653315 Tue 14 May 2019 09:38:15 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000996386 Tue 14 Feb 2023 15:56:39 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000925148 Tue 13 Dec 2022 15:37:32 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000925085 Tue 13 Dec 2022 15:02:31 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000616651 Tue 12 Dec 2017 10:07:42 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000494771 Tue 11 Dec 2018 09:38:20 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000630399 Tue 11 Aug 2020 14:49:37 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000794662 Tue 09 Mar 2021 13:25:37 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001133971 Tue 07 May 2024 09:58:24 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001133946 Tue 07 May 2024 09:44:23 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000444082 Tue 03 Sep 2019 12:59:02 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000431798 Tue 03 Oct 2017 11:28:10 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001010828 Thu 30 Nov 2023 09:41:07 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000622632 Thu 29 Mar 2018 12:36:01 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000537529 Thu 29 Jun 2017 14:09:28 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000435688 Thu 28 Sep 2017 10:36:06 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000721037 Thu 28 May 2020 09:43:15 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000513614 Thu 28 Jun 2018 11:28:37 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000537524 Thu 28 Jun 2018 10:34:27 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001133431 Thu 25 Apr 2024 09:48:16 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000646984 Thu 24 Jan 2019 19:43:32 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001139891 рям>лес. Удаление РОУ может быть связано как с переходом части в неорганическую форму, так и с разрушением высокомолекулярных органических веществ. Отмечается значительное изменение оптических параметров, что согласуется с поведением растворенного органического вещества во время фотолиза. Помимо этого, под воздействием инсоляции происходит трансформация органо-минеральных соединений, что приводит к изменению форм металлов. Наибольшие потери относительно контроля наблюдались для редкоземельных элементов (Y, La, Ce, Pr, Nd), а также Ti, V, которые в отдельных случаях достигают 70 % (значительнее в водах топи). Данные микроэлементы показывают схожее поведение с растворенным органическим углеродом, Al и Fe, что подтверждает важность органических и органо-Fe-Al-коллоидов, определяющих поведение большинства элементов в кислых водах с высоким содержанием органического вещества.]]> Thu 23 May 2024 11:26:55 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000577493 Thu 22 Jun 2017 12:42:33 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000925780 Thu 22 Dec 2022 11:08:33 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000550615 Thu 19 Oct 2017 10:36:45 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000436423 Thu 18 Jan 2018 13:34:34 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000582780 Thu 12 Oct 2017 17:08:29 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008913 99.5% C-CO2, <0.5% C-CH4) which is twice higher than the total dissolved C (organic and inorganic) riverine export flux during the same period. 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 ]]> 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 ]]> 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/koha:001067505 Thu 08 Feb 2024 10:56:19 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000651304 Thu 06 Jun 2019 19:30:48 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000434356 Thu 05 Oct 2017 14:20:40 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000723054 Thu 03 Sep 2020 14:43:11 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000902651 Thu 03 Nov 2022 09:49:58 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000901044 Sat 08 Oct 2022 10:32:51 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000847107 Mon 28 Feb 2022 11:04:56 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000578422 Mon 21 Aug 2017 11:06:10 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000578423 Mon 21 Aug 2017 11:06:08 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000578323 Mon 21 Aug 2017 10:03:11 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000997868 Mon 20 Mar 2023 09:37:20 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000535413 Mon 19 Mar 2018 11:55:02 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000620613 Mon 19 Feb 2018 10:39:34 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000925495 Mon 19 Dec 2022 15:45:40 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000901388 Mon 17 Oct 2022 14:24:10 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000465282 Mon 17 Dec 2018 11:01:29 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000453024 Mon 17 Dec 2018 10:52:05 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000486517 Mon 17 Dec 2018 10:03:16 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000787155 Mon 16 Nov 2020 11:02:15 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000893965 Mon 16 May 2022 11:31:27 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000625846 Mon 14 May 2018 10:53:22 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001015266 Mon 11 Dec 2023 14:07:29 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000528604 summer>autumn>winter. The ice formation in October included several stages: first, surface layer freezing followed by crack (fissure) formation with unfrozen water from the deeper layers spreading over the ice surface. This water was subsequently frozen and formed layered ice rich in organic matter. As a result, the DOC and metal (Mn, Fe, Ni, Cu, Zn, As, Ba and Pb) concentrations were highest near the surface of the ice column (0 to 20 cm) and decreased by a factor of 2 towards the bottom. The main implications of discovered freeze-driven solute concentrations in thermokarst lake waters are enhanced colloidal coagulation and removal of dissolved organic matter and associated insoluble metals from the water column to the sediments. The measured distribution coefficients of a TE between amorphous organo-ferric coagulates and lake water (<0.45 μm) were similar to those reported earlier for Fe-rich colloids and low molecular weight (<1 kDa, or <1–2 nm) fractions of thermokarst lake waters, suggesting massive coprecipitation of TE with amorphous Fe oxyhydroxide stabilized by organic matter. Although the concentration of most elements was lowest in spring, this period of maximal water coverage of land created a significant reservoir of DOC and soluble metals in the water column that can be easily mobilized to the hydrological network. The highest DOC concentration observed in the smallest (<100m2) water bodies in spring suggests their strongly heterotrophic status and, therefore, a potentially elevated CO2 flux from the lake surface to the atmosphere.]]> Mon 10 Dec 2018 12:52:19 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000499836 Mon 04 Sep 2017 15:59:01 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000486923 Mon 04 Sep 2017 12:01:06 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000444109 Mon 02 Sep 2019 13:01:48 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000792464 Mon 01 Feb 2021 10:08:10 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001016511 Fri 29 Dec 2023 10:24:37 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000659366 Fri 28 Jun 2019 15:54:30 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001133505 Fri 26 Apr 2024 16:15:18 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000660683 Fri 23 Aug 2019 10:53:14 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000437536 Fri 22 Sep 2017 12:37:10 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001016321 Fri 22 Dec 2023 14:15:38 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000894610 Fri 20 May 2022 16:53:35 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000494611 Fri 14 Dec 2018 10:11:03 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000453489 Fri 14 Dec 2018 09:49:57 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000486019 Fri 14 Dec 2018 09:42:56 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000794799 Fri 12 Mar 2021 13:45:48 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000794816 Fri 12 Mar 2021 13:45:32 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001132884 Fri 12 Apr 2024 09:40:34 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000898266 Fri 09 Sep 2022 09:27:46 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000657206 Fri 07 Jun 2019 09:41:12 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000723165 Fri 04 Sep 2020 09:44:17 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008787 Fri 03 Nov 2023 10:32:48 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008660 Fri 03 Nov 2023 09:29:51 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000996912 Fri 03 Mar 2023 09:20:15 KRAT ]]>
