Abstract

The full-scale investigations of the action of internal waves and inhomogeneous currents on the wind waves and the near-water layer of the atmosphere were carried out in the White Sea in 2009 - 2011 yr. Measurements were carried out from onboard of the scientific research vessel "Ekolog" by optical, radar and acoustic equipment. Hydrometeorological conditions during observations varied essentially. Wind speed varied from 0 to 15 m/s, speed of current from 0 to 1 m/s. Data about the field of current during different phases of tide are received. Internal waves and their manifestations on the sea surface are registered. The special features of the flow of the powerful tidal current (to 1 m/s) around the secluded underwater elevation and the spatial structure of surface anomalies in the field of these two-dimensional- heterogeneous currents are analyzed. Data about a change in the characteristics of reflected from the sea surface radar signal in process of development of wind waves are received. Experiments on procedure finalizing of the determination of sub-surface current speed according to the numerical data of radar measuring complex on the base of ship radar Icom MR-1000 and FURUNO 1942 MK2are carried out.
