A new algorithm for calculating the vertical velocity is suggested. Horizontal current velocity components are expressed through
level inclination and wind/temperature forcing. The acquired relations are given in the difference form, with the accuracy
being sufficiently high. The algorithm is tested using cases where a numerical solution is matched up with an exact one. The
derived data are subsequently analysed.

Data on the phosphorite mineralization, lithology, and variability of Lower Paleozoic rocks in the Zilair synclinorium and
Yuryuzan basin are given. Comparison of Lower Paleozoic rocks with type sections of phosphate-bearing rocks in the world suggested
their compliance with the phosphorite-enclosing rocks of the fine-grained phosphorite association. Analysis of the facies
variability of rocks indicate the possibility of discovery of large phosphorite deposits in the Yuryuzan and Syuren subzones
of the Western structural-facies zone. Phosphorite deposits are unknown in the synclinorium because of their instability during
hypergenesis and burial under allochthonous loose sediments of the Cenozoic. 相似文献

A map of the tectonic zoning of the sedimentary cover in the Deryugin Basin area was constructed based on the structural data.
For this purpose, a structural-tectonic map of the sedimentary cover was compiled using CDP seismic reflection and gravimetry
data. Depending on the size, spatial position, and orientation, the structural elements of different orders were grouped into
tectonic systems. The latters were subdivided into structural zones consisting of higher order structural elements in the
form of relative rises and troughs. The corresponding maps and schemes are also presented in this paper. 相似文献

The method and results of the study of granulometric composition of sediments of the Anapa bay bar are presented in this work. Along the extension, the Anapa bay bar hosts several areas with distinct granulomentric composition of sediments. The coastal variability of the bottom sediments is less expressive relative to land sediments and the pattern of the coastal distribution of granulometric composition reflects the local differences of hydrolithodynamic conditions of individual areas of the bay bar. These data are important for understanding the present-day lithodynamic processes and evolution of the geosystem of the Anapa bay bar. 相似文献

Peculiarities of the edge wave evolution a great distance away from the source are considered. It is shown that waveguide dispersion may result in discrimination of the region in a wave train corresponding to the Airy phase. The effect of the discrimination of the Airy wave in the remote zone for the model of a step-like shelf is compared with real edge waves (using the marigrams of tsunami observed in the Sea of Japan in 1983).Translated by Mikhail M.

As a result of the field studies conducted in 2010 of the spatial and temporal variability of the granulometric composition
of the bottom and beach deposits of the southern part of the Anapa bay bar, the tendency of a decrease in the average size
of the particles under the southward flow of the deposits of the coastal zone was revealed. The comparison of the data obtained
in 1949, 1979, and 2010 shows that the average diameter of the particles in the deposits of the underwater slope also gradually
decreases over the time. It was established that, with the decreasing of the particle sizes down to 0.1 mm, their nonrecoverable
deposition to a depth of more than 7 m increases. Since, in the southern edge of the Anapa bay bar, over 70% of the bottom
and about 60% of the beach deposits are represented by fractions smaller 0.16 mm, at this site the mass deposition of the
sand material to a depth occurs. Based on the data obtained, the particle size of the sandy material recommended for the restoration
of the beaches of the southern part of the Anapa bay bar was determined. 相似文献

This paper describes a projection variant of the integration-interpolation technique which is used to construct monotonic difference schemes for solving the problems for an integral stream function and a level surface. The results of model numerical computations are presented which demonstrate the efficiency of the proposed techniques.Translated by Vladimir A. Puchkin. 相似文献

A geological density section of the Deryugin Basin (western part of the Sea of Okhotsk) was studied along the profile Sakhalin Island-Deryugin Basin-Central Okhotsk Rise. The investigations were conducted by the method of gravity modeling, which allowed us to trace the density variations of the Earth’s crust layers along the lateral. The horizontal density stratification of the Earth’s crust layers was found, which assumes a stratified-block model of its structure. The established density structure of the Earth’s crust showed that the Deryugin Basin is located in the junction zone between the Sakhalin-Hokkaido microplate and the Okhotsk Sea Plate separated by a structural suture. The western and eastern edges of the basin belong to the aforementioned plates, respectively. It was assumed that accumulations of various mineral associations are confined to the suture zone, while the “granite” layer (basement) of the Deryugin trough walls in the western edge of the Deryugin Basin presumably contains secondary reservoirs of hydrocarbons. 相似文献
