In this paper, the ship-mounted cosmic muon detector designed at the Pacific Oceanographic Institution of the USSR Academy of Science and utilized for the purpose of developing optimal methods of registering charged particles by Cerenkov radiation under conditions of an intense light background in the ocean is reported. The principal electronic block diagrams and structural elements of the submersible detector are discussed, and an algorithm for recording cosmic muons is described which is based on exclusion of the ocean's high bioluminescent activity period from the instrument's exposure.Translated by V.

The Earth’s free oscillations are recorded for the first time in variations of the geomagnetic field measured at the Earth’s surface. The Earth’s free oscillations in the frequency range from 0.3 to 4 mHz manifest in the spectra of geomagnetic variations in the form of clearly expressed quasi-harmonic peaks. It is shown that the spectral amplitudes of the main modes of the Earth’s free oscillations are not constant and change with a periodicity corresponding to a lunar (sideral) month. The data obtained indicate the influence of oscillations in the internal geospheres on variations in the terrestrial magnetic field. The results provide new opportunities to study the Earth’s free oscillations and to specify their multiplet components. In addition, they also have certain implications for further research into the internal structure of the Earth and geodynamic processes in internal geospheres, on the basis of magnetometric data. 相似文献

This paper describes the results of the grain-size and mineralogical studies of the deposits of the tsunami of 1994 on Shikotan, Tanfil’ev, and Kunashir islands. The studies were carried out within the portions of the coast with different configurations, geomorphologic structures, lithodynamical environments, and character of the tsunami manifestation. The composition of the tsunami deposits is shown to be controlled mainly by erosion-accumulative processes during the tsunami events and is in many respects inherited from the matter sources. The tsunami deposits contain marine diatom species, whose richest assemblages were found within the areas where the material from the underwater coastal slope was redeposited. The data concerning the deposits of earlier historical tsunamis encountered in the same cross sections are discussed too. Their examination points to a similar development of the erosional-accumulative processes during tsunami events with the same intensity and an entrainment of the matter from the same sources. 相似文献
