A. V. Gavrilov  A. V. Konovalov  S. P. Nikiforov 《Seismic Instruments》2011,47(3):271-277

The operation of a new domestic seismic signal recorder Delta 03 is analyzed. The optimization of technical requirements on parameters of the recorder, the test cycle, adjustment in the process of testing individual technical solutions, and improvement of the device were carried out in close cooperation with its designers from OOO Logic Systems (Ramenskoye, Moscow Region). At the time of writing, the recorder Delta 03 is a robust device that is recommended for use in seismic monitoring systems of various levels.  相似文献   

Comparison of the results of determination of the carbonate system and the total alkalinity of seawater according to the data obtained by using different analytic methods     

D. S. Khoruzhii  E. I. Ovsyanyi  S. K. Konovalov 《Physical Oceanography》2011,21(3):182-194

On the basis of the data of hydrochemical investigations of waters of the Sevastopol Bay, we discuss the results of the analysis of the carbonate system and the total alkalinity of seawater obtained by using two methods. By using the linear method of least squares, we compare the results of the analysis of the carbonate system according to pH values and the total alkalinity and according to pH values and dissolved inorganic carbon. It is shown that, within the investigated range of pH values, Alk, and TCO₂, the mean relative deviations of values of the fugacity of CO₂ and the concentrations of dissolved CO₂ and CO₃²⁻ ions computed by using different input parameters are equal to 3.0, 1.0, and 9.6%, respectively.  相似文献   

New architecture of an automated system for acquisition,storage, and processing of seismic data     

A. A. Stepnov  A. V. Gavrilov  A. V. Konovalov  L. Ottemöller 《Seismic Instruments》2014,50(1):67-74

Features of the new architecture of an automated system for acquisition, storage, and processing of seismic data are considered in detail. The system is based on SEISNET and SEISAN software. Specific technologies, software, and examples of the interconnection of system components are presented. The functionality of the system and the data life cycle are shown. An example of the implementation of the new architecture in the existing seismic monitoring network in the northern part of Sakhalin Island is examined.  相似文献   

Method for estimating admixture content in seawater using operative spectrophotometry     

V.?V.?RostovtsevaEmail author  B.?V.?Konovalov  I.?V.?Goncharenko  D.?V.?Khlebnikov 《Oceanology》2017,57(4):505-519

The paper discusses spectra of the radiance coefficient of the sea surface measured in the open ocean and in coastal waters, and different kinds of these spectra corresponding to the water types are revealed. The focus is the method of measuring the radiance coefficient from a moving ship with a hyperspectral spectrophotometer. The results of studying a water area of Russia’s Black Sea coast at river mouths are presented. A new calibration method that can process measurement results taking into account the impact of cloudiness and wind has been proposed and tested. The concentrations of the main admixtures in natural seawater in the studied water area are estimated according to the obtained spectra; these estimates are compared to the results of direct analysis of water samples. It has been shown that the method of remote measurement of the sea radiance coefficient from on board a ship makes it possible to obtain operative maps of the spatial distribution of the main seawater admixtures.  相似文献   

Polarography of the bottom sediments in the Sevastopol Bay     

N. A. Orekhova  S. K. Konovalov 《Physical Oceanography》2009,19(2):111-123

By the method of polarographic profiling performed with the help of an Au-Hg glass microelectrode, we obtained the first high-resolution vertical profiles of the distributions of oxygen, sulfides, oxidized and reduced forms of iron, reduced manganese, and iron monosulfide in pore waters of the bottom sediments in the Sevastopol Bay. It is shown that the regional features of the vertical distributions of the main polarographically active compounds are determined by the combination of several factors: the contents of organic carbon and iron and the sizes of particles of the sediments.  相似文献   

Estimation of transboundary transport contribution to the air pollution in the far east region using the chemistry transport model     

I. N. Kuznetsova  I. B. Konovalov  A. A. Glazkova  E. V. Berezin  M. Beekmann  E. -D. Schulze 《Russian Meteorology and Hydrology》2013,38(3):150-158

The CHIMERE mesoscale chemistry transport model is used for the quantitative assessment of the contribution of transboundary transport of anthropogenic admixtures from China to the surface concentrations of major suspended pollutants, aerosol PM₁₀, ozone O₃, and nitrogen oxides NO_x in the Far Eastern region. Analyzed in detail are the time series of concentration of mentioned substances computed with the model taking account and not taking account of anthropogenic emissions in China. It is revealed that the transboundary transport of anthropogenic pollutants can cause the recurring episodes of manyfold increase in the concentration of PM₁₀ in the south of Khabarovsk region, as well as more rare variations of O₃ and NO_x concentration. The trajectory and synoptic analysis demonstrated that the episodes of the increase in the concentration of PM₁₀ and O₃ in the south of the region mainly depend on the carryover of air masses from northeastern China in the front part of continental cyclones.  相似文献   

Regularities of seasonal variations in the content and distribution of oxygen in waters of the Sevastopol Bay     

S. V. Svishchev  S. I. Kondrat’ev  S. K. Konovalov 《Physical Oceanography》2011,21(4):280-293

We study the regularities of annual variations in the concentration of oxygen and the degree of saturation of waters in the Sevastopol Bay with oxygen in 1998–2009. The three-dimensional specific features of seasonal variations in the distribution of oxygen in waters of the Sevastopol Bay are revealed. Two periods can be separated in the annual course of the content of oxygen in the surface layers of waters in all parts of the bay: the period of supersaturation in March–September and the period of undersaturation in October–February. In the bottom layer of waters in all parts of the bay, we observe the undersaturation of waters with oxygen for the whole year.  相似文献   

Intraannual and long-term variations of the carbonate system of the aerobic zone in the black sea     

O. G. Moiseenko  S. K. Konovalov  O. N. Kozlovskaya 《Physical Oceanography》2011,20(6):435-450

We provide an expert quality assessment of the data for 1932–1993 and used these data to perform the numerical analysis of the carbonate system of the aerobic zone in the Black Sea. The intraannual and long-term variations of the carbonate system are studied in the abyssal part of the sea for 1960–1993. We propose explanations of the intraannual variations of the analyzed system for various layers of the aerobic zone and reveal long-term variations of the pH values, total alkalinity, and the ratios of the components of the carbonate system. We discover and explain the observed increase in the concentrations of TCO₂ and CO₂ and the partial pressure of carbon dioxide pCO₂, as well as a decrease in pH values and the concentration of CO₃²⁻ in waters of the aerobic zone of the Black Sea.  相似文献   

Validation of chemistry transport model of the lower atmosphere in the central European region of Russia using ground-based and satellite measurement data     

I. B. Konovalov  N. F. Elanskii  A. M. Zvyagintsev  I. B. Belikov  M. Beekmann 《Russian Meteorology and Hydrology》2009,34(4):236-242

A modern three-dimensional chemistry transport model is adopted for computation of air pollution with photo-oxidants in the Moscow megalopolis and in the several neighboring regions. Along the vertical, the model covers the entire troposphere and has a two-scale horizontal structure, when the resolution of the “inserted” domain is about 13 km. The model computation results are compared with the satellite tropospheric nitrogen dioxide measurements and ground-based measurements of the surface ozone concentration. The analysis results of one of the episodes of enhanced ozone content is considered as an example of a possible use of the model considered as a diagnostic tool for studying issues connected with the air pollution in the region under consideration.  相似文献
