On the evaluation of displacement and deformation in tidal waves according to digital records of STS-2 and KSESh-R seismometers

A procedure for eliciting displacements in tidal waves from seismograms of broadband velocimeters like STS-2 and KSESH-R and the evaluation conversion of these displacements into vertical or volumetric deformation is proposed.     

Bottom sediments of the oldest reservoir in Moscow region

The methodological features and results of two soil surveys of the Senezh Reservoir carried out in 1992 and 2006 as a part of multidisciplinary limnological studies of this large recreation water body with the aim to monitor its ecological state and prepare recommendations for water protection measures are analyzed     

The geology, hydrodynamics, and the oil and gas potential of the Kosheleva steam-water field in Kamchatka

This paper considers the geology, hydrodynamics, and oil and gas occurrences in the Kosheleva vapor-dominated field related to the activity of the Kosheleva Volcano. The hydrodynamic peculiarities of this field allow the upper boundary of the vapor zone to be outlined. One notes an intimate connection between vapor-dominated hydrothermal occurrences and the occurrences of oil and gas containing heavy hydrocarbons, including even C₇H₁₂, as well as methane.     

Solar corona top heating

The solar magnetic field fragmentation into thin magnetic tubes above the photosphere makes it possible to transform and factorize MHD equations analytically and to obtain explicit expressions for Alfvén and magnetosonic fields. A physical model that enables an explanation of the effect of strong heating of the solar chromosphere and corona has been proposed. This model makes it possible to estimate analytically a powerful Alfvén disturbance entering the chromosphere due to convective motions of the photosphere and a thermal release due to a three-wave interaction within the chromosphere.
