Scientific interests:
Physical oceanography, remote sensing of the Earth from space, long-term variability of the large-scale climatic frontal zones of the World Ocean, frontal zones and long-term variability in the seas (Black, Aegean, Caspian, Yellow, etc.), the role of abiotic factors in the introduction of alien species into the seas.

Main research results:
Ship measurements confirmed an existence of a multi-frontal structure of large-scale oceanic frontal zones (OFZ). The types of multi-frontality were distinguished and it was shown that the intensity of the fronts within the OFZ is proportional to the zonal-mean gradient of the SST, which indicates the presence of a typical horizontal scale (~30 km) of the prevailing local frontogenetic mechanism.

For the first time, the global geography, climatology and seasonal variability of the surface manifestations of the main climatic OFZs in the World Ocean were presented based on the analysis of regular global satellite measurements of SST.

It was shown that, in the first approximation, the seasonal and interannual variability of the frontogenesis in the climatic frontal zones of the mid-latitudes can be explained in the framework of a simple one-dimensional model of a homogeneous mixed layer.

For the first time, the existence of long-term (quasi-decadal) variability of all main climatic frontal zones of the World Ocean (subpolar, subtropical, equatorial), manifested in variations of their intensity and the latitudinal position of the core, has been documented, and quantitative estimates of this variability have been obtained.

For the first time, statistically significant correlations were found between the long-term variability of atmospheric forcing (the meridional shift of the zonal wind component) and variations of the main climatic OFZ.

A positive correlation was found between the variability of the North Atlantic Oscillation (NAO) and the intensity of the subpolar OFZ in the North Atlantic.

For the first time, the decadal shift of the intensity regime of the Canarian upwelling system in the early 1990s was documented and studied in detail, and the effect of this shift on the bioproductivity of the system was shown.

It was shown that the section of the Kuroshio frontal zone on the border of the East China Sea experiences interannual variability with periods corresponding to the period of fluctuations of the El Nino system (ENSO; 4-5 years).

For the first time, the long-term variability of the front in the northwestern part of the Black Sea was related to the variability of the average SST, and a conceptual scheme of the influence of large-scale atmospheric processes (NAO and EAWR) on the long-term variability of the SST in the Black and Aegean Seas through variations in the heat flow to the water area associated with changes in the wind field was proposed.

The influence of wind on the population concentration of the invader  Mnemiopsis leidyi in the Black Sea was studied.

Having considered ctenophore Mnemiopsis leidyi, one of the most invasive and harmful planktonic species, its current environmental niche and possibility of dispersal under global warming were assessed.
