A rock behavior experiment with uniaxial compression revealed the effect of acoustic activity in loaded fluid-saturated Berea sandstone samples in response to an electric current. It is established that it is substantially intensified in periods of the current impact and decreases after its cut-off. The current impact also results in a growth of radial deformation indicating an increase in the sample volume. The effect of acoustic activation increases in response to increased heat emitted by the electric current during its flow through the sample, which allows the discovered effect to be explained by initiation of its destruction due to thermal expansion of the fluid in rock interstices and fissures. 相似文献

The satellite ionosondes in highly elliptical orbits are proposed to be used for the task of continuous monitoring of the Arctic ionosphere. The monitoring scheme with the ionosonde location aboard the Arktika-M satellites is presented. The calculations of the vertical topside and transionospheric sounding using the SIMP1 ionospheric model are performed, which show the feasibility of continuous monitoring. 相似文献

A three-dimensional geomechanical model of Southern California, including mountain relief, fault tectonics, and characteristic
internal borders, such as the roof of the consolidated crust and Moho surface, was created. The initial stress state of the
model is determined by the gravitational force and horizontal tectonic movement, established on basis of GPS observations.
Monitoring of variations in the stress state of the Earth’s crust and lithosphere, which are generated by seismic processes,
has shown that the model enables us to predict an increase of seismic activity in a region and to mark the places in which
average earthquakes can occur in the following two weeks. 相似文献

Summary. The determination of induced magnetic fields of synoptic ocean movements is considered in the case of horizontal uniformity of the bottom conductivity. The problem of calculation of hydrodynamic parameters is solved by means of induced fields. These appear to depend closely on the appearance of barotropic or baroclinic parts in the synoptic ocean movement. The different properties of fields from parts of the above permit us to separate hydrodynamic parameters of complex ocean movements into barotropic and baroclinic parts by means of magnetic measurements. 相似文献

This paper presents an analysis of the mass spectrometry measurement data for the ion composition of the upper atmosphere at altitudes of 810–830 km. A radio frequency mass spectrometer RIMS was mounted on the Meteor-M 1 and 2 spacecraft that were launched in 2009 and 2014. The measurements were carried out by the contact method. The analysis of the seasonal data from January 1, 2016, to January 1, 2017, reveals a seasonal variation in the oxygen ion concentration associated with the Sun’s position. An increase in the O+ concentration for the South Pole and a decrease for the North Pole are observed in the regions of magnetic anomalies. The greatest increase in the ion concentration is detected in the region of the Brazilian magnetic anomaly. There are also minor increases in the O+ concentration that can be associated with the North American Anomaly over Yellowstone National Park. 相似文献

The Raman scattering and fluorescence spectra were first obtained for the water of sea surface microlayers (SML) of 1 and 0.2 mm thickness (sampled with a Garrett net and a Lapshin capillary sampler, respectively). For reference, samples of water below the SML (from the layer of 0.5 m) were also taken. Substantial differences were found for the values of the normalized intensity of the fluorescence (the number of photons from the volume unit in response to a unit of excitation) between the aqueous humic substances and, presumably, oil hydrocarbons and proteins. Some slight but analyzable differences in the shapes and location of spectral bands were also found. These latter allow one to determine the content of salts and the characteristics of complicated organic compounds in the SML and to compare them to those within the water volume. 相似文献

The effects that the two Kuril undersea earthquakes of November 15, 2006, and January 13, 2007, had on the ionosphere are
considered on the basis of the results of measurements of variations in the ionosphere’s total electron content obtained from
the network of Russian GPS stations. Owing to a favorable location of the stations, the ionosphere’s response to these earthquakes
is studied in the vicinity of and far (up to distances on the order of 1000 km) from their epicenters. It is found that the
apparent velocity of propagation of ionospheric disturbances (1–3 km/s) significantly exceeds the velocity of propagation
of tsunami waves caused by earthquakes; this fact can be used in forecasting tsunamis. It is shown that, in parallel with
the known type of ionospheric response to earthquakes in the form of an N-wave, there is also its response in the form of an inverted N-wave in the vicinity of and far from their epicenters. The causes of occurrence of the response in the form of an inverted
N-wave are interpreted. 相似文献
