The most important research results obtained in 2012-2016

  • High-resolution paleoceanographic, micropaleontological, sedimentological and paleoenvironmental studies of the Middle-Late Pleistocene to Holocene sediments have been carried out in the tropical Indo-Pacific, Black Sea, Barents and Bering Seas. Our results and correlations of paleoceanographic events in remote regions suggest an important role of the Thermohaline Circulation in global teleconnections on glacial-interglacial and millennial scales.
  • In the Atlantic, a new line of research is developing since 2009. We carry on reconstructions of erosional-accumulation activity of bottom currents and the resulting contourite sedimentation. Eight Transatlantic expeditions have been organized to collect the sediment cores on the high-resolution seismic profiles. The so-called Ioffe Drift has been discovered. Its formation started in Miocene and several hiatuses are documented in the sediment cores retrieved from this drift. The evidences of contourite occurrence are collected on the Ceara Rise, in the Equatorial Mid-Oceanic Channel, in the valleys of transform faults of the Mid-Atlantic Ridge, in some erosional channels of Argentine Basin, and on the terraces of Patagonian Continental Slope.
  • In the tropical Pacific, orbitally controlled variations in surface bioproductivity are documented during the Milddle-Late Pleistocene in cooperation with our French partners. Besides, enhanced productivity values in the Eastern Equatorial Pacific are associated with changes in atmospheric circulation and vigor of upwelling at Costa Rica Dome. High productivity values are typical of terminations, i.e. the intervals of rearrangement of the global thermohaline circulation.
  • The glacial-interglacial and millennial variability in bioproductivity, bottom-water oxygenation and sedimentation are under study in the Bering Sea. The results point to the strong impact of changes in global sea level and teleconnections with the North Atlantic and Asian monsoon on the regional paleoenvironmental conditions.
  • The high-resolution reconstructions of postglacial changes in facies system and paleoenvironments in the Barents Sea resulted in identification and correlation of millennial climatic events. Paleodata suggest that the Atlantic water flow (as a signature of the Atlantic meridional overturning) is one of the major factors of the Postglacial climatic variability in the Barents Sea on millennial to decadal time scales.
  • Our study demonstrated that coquina facies characterizes the transition from the postglacial Neoeuxinian Lake to the Black Sea in the early Holocene as a result of the global sea level rise and opening of Bosphorus Strait. The major paleoceanographic events are reconstructed on the NE shelf during the Holocene and unique data collected on the modern ecological preferences of several ostracod species, including the taxa of Caspian origin.
