Impact of snow deposition on major and trace element concentrations and elementary fluxes in surface waters of the Western Siberian Lowland across a 1700 km latitudinal gradient
In order to better understand the chemical composition of snow and its impact on surface water hydrochemistry in the poorly studied Western Siberia Lowland (WSL), the surface layer of snow was sampled in February 2014 across a 1700 km latitudinal gradient (ca. 56.5 to 68° N). We aimed at assessi...

| description | In order to better understand the
chemical composition of snow and its impact on surface water hydrochemistry
in the poorly studied Western Siberia Lowland (WSL), the surface layer of
snow was sampled in February 2014 across a 1700 km latitudinal gradient (ca.
56.5 to 68° N). We aimed at assessing the latitudinal effect on both
dissolved and particulate forms of elements in snow and quantifying the
impact of atmospheric input to element storage and export fluxes in inland
waters of the WSL. The concentration of dissolved+colloidal
(< 0.45 µm) Fe, Co, Cu, As and La increased by a factor of
2 to 5 north of 63° N compared to southern regions. The pH and
dissolved Ca, Mg, Sr, Mo and U in snow water increased with the rise in
concentrations of particulate fraction (PF). Principal component analyses of
major and trace element concentrations in both dissolved and particulate
fractions revealed two factors not linked to the latitude. A hierarchical
cluster analysis yielded several groups of elements that originated from
alumino-silicate mineral matrix, carbonate minerals and marine aerosols or
belonging to volatile atmospheric heavy metals, labile elements from
weatherable minerals and nutrients. The main sources of mineral components in
PF are desert and semi-desert regions of central Asia.

The snow water concentrations of DIC, Cl, SO<sub>4</sub>, Mg, Ca, Cr, Co, Ni, Cu,
Mo, Cd, Sb, Cs, W, Pb and U exceeded or were comparable with springtime
concentrations in thermokarst lakes of the permafrost-affected WSL zone. The
springtime river fluxes of DIC, Cl, SO<sub>4</sub>, Na, Mg, Ca, Rb, Cs, metals
(Cr, Co, Ni, Cu, Zn, Cd, Pb), metalloids (As, Sb), Mo and U in the
discontinuous to continuous permafrost zone (64–68° N) can be
explained solely by melting of accumulated snow. The impact of snow
deposition on riverine fluxes of elements strongly increased northward, in
discontinuous and continuous permafrost zones of frozen peat bogs. This was
consistent with the decrease in the impact of rock lithology on river
chemical composition in the permafrost zone of the WSL, relative to the
permafrost-free regions. Therefore, the present study demonstrates
significant and previously underestimated atmospheric input of many major
and trace elements to their riverine fluxes during spring floods. A broader
impact of this result is that current estimations of river water fluxes
response to climate warming in high latitudes may be unwarranted without
detailed analysis of winter precipitation. |
