An approach to the retrieval of sea wave spatial spectra based on satellite optical imagery in linear and nonlinear approximations is described. Physical mechanisms of the formation of disturbed sea surface brightness fields recorded by remote sensing equipment are analyzed. Wave spectra retrieval methods using brightness field formation models that consider linear and nonlinear dependencies on sea surface slopes are suggested. A method for the construction of operators that retrieve the spatial spectra of surface wave slopes and elevations from aerospace imagery and take into account nonlinear modulations of disturbed sea surface brightness fields is developed. This method is based on the numerical simulation of sea surface images and the construction of a retrieving operator with respect to a set of parameters determined by aerospace imaging conditions. Examples of the use of the developed methods are given. © 2016, Pleiades Publishing, Ltd.

Peculiarities of the formation of carbon gas and fine aerosol emissions into the atmosphere during wildfires are analyzed. A prompt satellite monitoring system and technique for the assessment of burnt areas and volumes of CO2, CO, and PM2.5 emissions from wildfires are described. The results of satellite monitoring of the Russian Federation and some Russian regions for different months over 2010–2014 are given; burnt areas and volumes of carbon gas and aerosol emissions throughout the entire territory are assessed. The peculiarities of seasonal frequencies of wildfires and volumes of hazardous gas and fine aerosol emissions in the regions under study are identified. © 2016, Pleiades Publishing, Ltd.

The results of studying sea-wave spectra in a wide wavelength range using high resolution (0.5–1.0 m) satellite optical imagery spectra and the results of measurements carried out from an oceanographic platform using string-wave recorders, stereo system, and drifting wave buoys are presented in this paper. The wave spectra retrieved from satellite imagery and sea-truth data have been compared. A comparison has shown the adequacy of the purposely developed retrieval methods. Power approximation indices for spatial spectra in the 0.04–5.0-m wavelength range have been found. It has been shown that the wave spectra measured experimentally by satellite-based and in-situ methods best approximate the Toba spectrum. © 2016, Pleiades Publishing, Ltd.

The analysis of inertial oscillations on the Gelendzhik shelf of the Black Sea is presented. Spectral characteristics of the current fields are studied based on the measurements taken by the acoustic Doppler current profiler. Strong variability of the inertial oscillation hodographs at variations in the background shear current and diverse forms of inertial oscillations measured at a fixed point at various values of the shear current are revealed. The relation between the passage of the multidirectional jets and the trains of inertial oscillations inside the jets in the studied region are established. © 2017, Pleiades Publishing, Ltd.

The Pan-Eurasian Experiment (PEEX) is a multidisciplinary, multiscale and multicomponent research, research infrastructure and capacity-building program. PEEX has originated from a bottom-up approach by the science communities and is aiming at resolving the major uncertainties in Earth system science and global sustainability issues concerning the Arctic and boreal pan-Eurasian regions, as well as China. The vision of PEEX is to solve interlinked, global grand challenges influencing human well-being and societies in northern Eurasia and China. Such challenges include climate change; air quality; biodiversity loss; urbanization; chemicalization; food and freshwater availability; energy production; and use of natural resources by mining, industry, energy production and transport sectors. Our approach is integrative and supra-disciplinary, recognizing the important role of the Arctic and boreal ecosystems in the Earth system. The PEEX vision includes establishing and maintaining long-term, coherent and coordinated research activities as well as continuous, comprehensive research and educational infrastructure and related capacity-building across the PEEX domain. In this paper we present the PEEX structure and summarize its motivation, objectives and future outlook. © 2015 Author(s).

A typical feature of the large scale interaction of seismic active tectonic provinces of Southern California, which is expressed in a relatively fast jump change in the stress state of the crust over 0.5 month, is revealed on the basis of a geomechanical model and the results of instrumental observations for displacements of the crust. This provides us with new possibilities for the short-term prediction of significant seismic events for a period of a week to a month. © 2016, Pleiades Publishing, Ltd.

We consider the specific features of remote registration of sources of natural hydrocarbon gas seeps in Arctic water areas to substantiate the possibility of aerospace monitoring of shelf zones prospective for hydrocarbons. The main characteristics of degassing sources and their manifestations at the surface and in the water column have been determined. The areas of the Arctic shelf with potential natural gas shows that can be detected through remote sensing have been identified. We analyze promising aerospace methods for the registration of gas shows in the sea and give examples of hydrocarbon gas seeps observed from space. © 2015, Pleiades Publishing, Ltd.

The results of satellite monitoring of the environmental state of impact Arctic regions subjected to heavy anthropogenic influence are given. We analyze arrays of vegetation indices and complex spectral transformations derived from processed long-term (1973–2013) satellite data for areas around the cities of Arkhangelsk and Zapolyarny (Murmansk oblast). These data have been used to evaluate the changes in the state of the environment and reveal areas of peak anthropogenic impacts causing significant morphologic changes in all kinds of geosystems and strongly affecting the Arctic natural ecosystems. We have identified the impact regions that are subjected to peak anthropogenic impact and found that these areas are associated with specific industrial facilities. © 2015, Pleiades Publishing, Ltd.

The data on currents near Oahu Island (Hawaii) measured using bottom acoustic current profilers placed at the edge of the shelf in Mamala Bay are analyzed. The variations in the amplitude of inertia-gravity waves (IGWs) are compared with those in background low-frequency currents using specially designed indicators of variations in the magnitude and direction of the currents. It is established that a good connection between the wave amplitude and variability of background currents is observed in cases of local IGW generation, especially if the currents rotate clockwise. This connection becomes weaker in the presence of waves coming from far sources, the role of which can be played, in particular, by IGWs excited by drain water jets flowing from a deep-water diffuser. The obtained results show that IGWs can be associated not only with the action of wind, but also directly with any restructuring of the current field inside the ocean. © 2015, Pleiades Publishing, Ltd.
