Results of observations of tidal strains of the crust in the tectonically active Elbrus area of the Northern Caucasus carried out with the use of the Baksan SSAI laser interferometer strainmeter over the period from 2003 through 2006 are presented. Harmonic analysis is performed with the help of the ETERNA software package. Statistically significant time variations in the amplitudes of the main tidal waves M 2 and O 1 are revealed. The influence of the topography on tidal strains in the Baksan gorge is estimated at 22% (an increase in the measured strain values). The reduced amplitude factors of the main diurnal (O 1) and semidiurnal (M 2) waves are underestimated. Numerical modeling of tidal anomalies produced by regional heterogeneous inclusions is performed in a 2-D approximation. The observed anomaly of the M 2 wave (12%) is shown to be due to the influence of the main magma-controlling fault associated with the deep magma source of the Elbrus dormant volcano. 相似文献

The crystal chemistry of Fe ions in Cr-spinel from the largest Ural ultramafic massifs has been studied by Mössbauer spectroscopy at room temperature and the boiling temperature of liquid nitrogen. The spectra substantially depend on the mineral composition (stoichiometry) and measurement temperature; Fe2+ and Fe3+ doublets significantly overlap; the Fe2+ doublet lines are markedly broadened. According to the Mössbauer data, the degree of iron oxidation is 7–35% and appreciably differs from that in the stoichiometric approximation. The disturbance of integral stoichiometry by di- and trivalent cations (deviation of the Me3+/Me2+ value from 2.0) may be caused not only by partial inversion of the mineral structure but also by local micro- and nanoscale heterogeneity of the mineral, clustering of Fe2+ and Al (Cr, Fe3+) cations, and the appearance of associates. Possible application of the QS-distribution method for analyzing nonequivalent nuclear iron states and the thermal dynamics of Mössbauer spectra for studying local clustering effects of iron cations is discussed. It is shown that these approaches give new information on local heterogeneity of structural sites occupied by iron ions. 相似文献

The paper is based on the experimental data obtained by the Arctic and Antarctic Research Institute during the expeditions
carried out in 2001–2008 within the frameworks of the Ice Research Program of Lukoil Co. in the northwestern part of the Caspian
Sea. The in situ data processing and their statistical analysis enabled to obtain new information on the geometry of ice formations
and distribution of main morphometric parameters of ice hummocks and stamukhas. The regularities are revealed of distributions
of morphometric characteristics and parameters of the internal structure of ice hummocks and stamukhas. 相似文献

In accordance with the contract of the LUKOIL Oil Company, a cooperation of the Roshydromet organizations (Planeta Research Center for Space Hydrometeorology, a main contractor, Hydrometeorological Research Center of the Russian Federation, Arctic and Antarctic Research Institute, and State Oceanographic Institute) carried out in 2008 complex studies of the hydrometeorological and ice conditions for the Filanovskii oil- and gas-field facility construction on the northwestern shelf of the Caspian Sea. Three expeditions were organized and conducted within that project: a helicopter ice research expedition (specialists from the Arctic and Antarctic Research Institute carried out a huge volume of measurements of physicomechanic properties of level, rafted and hummocked ice, and morphometric characteristics of ice piling, hummocks, and stamukhas); specialists from the State Oceanographic Institute organized a ship expedition on studying sea ground exaration formed due to impacts of ice formations (hummocks and stamukhas) using hydro-radar and echo-sounder surveys as well as a complex hydrometeorological and hydrochemical expedition with five autonomous buoy stations mounted in two months. From the moment of ice formation to the end of the expedition activity, an operational space monitoring of the northwestern Caspian Sea was carried out at the Planeta Research Center for Space Hydrometeorology. Based on the NOAA, TERRA, and AQUA satellite data, corrected and geographically fixed satellite images of the area of activity were issued with a periodicity of 6 times per day; index maps on the ice situation (twice a week) and ice situation forecasts (lead-time of 1–7 days). Besides, long-term series of satellite data on the northwestern Caspian Sea are collected and processed: their results are used for estimating seasonal and interannual variability of the drift ice and fast ice. Specialists of the Hydrometeorological Research Center of the Russian Federation completed the work on processing and analysis of library materials, research/technical reports, handbooks, expedition observational data, and on hydrodynamic and probability modeling of long-term series of hydrological, meteorological, and partly ice data. In particular, basic characteristics of the hydrological regime (sea level, currents, and waving) are calculated for the place of the oil platform location and along the pipeline routing. Tentative local specifications on the hydrometeorological regime in the Filanovskii field are worked out based on the results of the work performed. 相似文献

This paper presents measurements for the 1987–2016 period; these include inclined distances and elevations between geodetic monuments in the deformation site in the Ust’-Kamchatsk area. These data are important for future investigators, because measurements can be made in the distant future in order to compare with the respective past values. This area has been accumulating deformation for the last 27 years along the direction perpendicular to the Kuril–Kamchatka Benioff zone, reaching values of approximately (5?10) × 10–6. The compression involves a northwest tilt of the ground surface. 相似文献
