Detailed knowledge of the flood period of Arctic rivers remains one of the few factors impeding rigorous prediction of the effect of climate change on carbon and related element fluxes from the land to the Arctic Ocean. In order to test the temporal and spatial variability of element concentration in the Ob River (western Siberia) water during flood period and to quantify the contribution of spring flood period to the annual element export, we sampled the main channel year round in 2014–2017 for dissolved C, major, and trace element concentrations. We revealed high stability (approximately ≤10% relative variation) of dissolved C, major, and trace element concentrations in the Ob River during spring flood period over a 1‐km section of the river channel and over 3 days continuous monitoring (3‐hr frequency). We identified two groups of elements with contrasting relationship to discharge: (a) DIC and soluble elements (Cl, SO4, Li, B, Na, Mg, Ca, P, V, Cr, Mn, As, Rb, Sr, Mo, Ba, W, and U) negatively correlated (p < 0.05) with discharge and exhibited minimal concentrations during spring flood and autumn high flow and (b) DOC and particle‐reactive elements (Al, Fe, Ti, Y, Zr, Nb, Cs, REEs, Hf, Tl, Pb, and Th), some nutrients (K), and metalloids (Ge, Sb, and Te), positively correlated (p < 0.05) with discharge and showed the highest concentrations during spring flood. We attribute the decreased concentration of soluble elements with discharge to dilution by groundwater feeding and increased concentration of DOC and particle‐reactive metals with discharge to leaching from surface soil, plant litter, and suspended particles. Overall, the present study provides first‐order assessment of fluxes of major and trace elements in the middle course of the Ob River, reveals their high temporal and spatial stability, and characterizes the mechanism of river water chemical composition acquisition. 相似文献

We observed the behavior of the pointer of an asymmetric torsion balance (TB) at solar eclipse dates and on other off-eclipse days. A peculiar reaction of the miniature TB different from its reaction at off-eclipse time was recorded for some solar eclipses. The relative positions of the Earth, Moon, and Sun are among the possible factors affecting the position of the TB pointer. A time shift between the maximum phase of a solar eclipse and the maximum TB reaction was detected. We conclude that base observations of such phenomena from different points of the terrestrial globe are necessary. 相似文献

The results of satellite monitoring of the state of northern territories disturbed by oil production are presented by the example of the Usinsk oil field in the Komi Republic. The sets of vegetation indices formed by the results of processing long-term series of multispectral satellite images for the period from 1988 to 2014 are analyzed. They are used to assess long-term environmental changes, to reveal the most disturbed zones, and to estimate the dynamics of changes in the vegetation cover area caused by the extraction and transportation of hydrocarbons. 相似文献

A device for recording positions of a beam of an extralight torsion balance is developed, mounted, and tested by the practice
of astronomical observations. The device makes it possible to completely automate the process of observations under constant
monitoring of the measurement results in real time. The principle of color division of stationary marks which specify the
meridian direction from a mobile marker is implemented owing to application of different luminescent paints and a source of
UV radiation. In contrast to other recording systems of such type, the device described makes it possible to minimize convective
air flows inside the chamber of a torsion balance and to drastically improve the accuracy of determining the beam direction
at which the error of individual determination is ±0.172°. Long-term observations performed with the given device made it
possible to reveal a distinct daily cycle in the behavior of a torsion balance, the nature of this cycle still being unclear. 相似文献
