Bio

Dr. Igor Dmitrenko is working on the Nansen and Amundsen Basins Observational System project. The main aspects of his research cover the variability of subsurface warm Atlantic water input along the continental slope of the Siberian Arctic from the mesoscal to synoptical and seasonal time scale of variations. The original temperature, salinity and current records from the several long-term moorings, deployed on the continental slope of the Laptev Sea and equipped with temperature, salinity and current profilers, are examined to evaluate the role of atmospheric forcing in formation of Atlantic water layer variability. The redistribution of river run-off water over the shelf of the Laptev and East-Siberian seas is also one of his research interests. The hydrographic historical Russian data are revised in order to evaluate the main drivers of river plume interannual variability, shelf-basin interaction as well as the role of ice cover during winter. The impact of coastal polynya system, well known as a Great Siberian Coastal Polynya, is also examined in respect of salinity anomaly formations due to brine rejection.
