Description
Summary:We present data of measurements of thermohaline and bio-optical fields in the surface layer of the Kara Sea carried out in September 2012, during the 59th cruise of the R.V Akademik Mstislav Keldysh . Measurements were performed during vessel motion along the expedition route using a pump-through CTD system (temperature and salinity) and UV fluorescent lidar (concentrations of chlorophyll, total suspended matter, and dissolved organic matter) with a high spatial resolution (about 10–100 m). Detailed sea-area distribution maps of the above parameters are presented, frontal zones are detected, T , S diagrams for the surface water layer are constructed, and basic water types are identified. It is shown that Ob–Yenisei freshwater runoff is a main factor affecting properties of the surface layer. In the second part of this paper, a numerical model of the dynamics of continental runoff in the Kara Sea is suggested. Model experiments were carried out under real wind conditions of August–September 2011 (NCAR/NCEP reanalysis); the model was validated on the basis of in situ data collected during the cruise.
