Section: Biology UDC551.465.4AuthorsAverkiev Alexander SergeevichRussian State Hydrometeorological University (Saint-Petersburg, Russia) e-mail: asav@rshu.ru AbstractThe areas of increased primary productivity in a sea are the important component of marine ecosystems, the key link for the formation of the fishing areas. The paper presents the main mechanisms of formation of the zones of increased productivity and diagnostics of their development in the Barents Sea. Observations of zones are effectively carried out with the help of satellite techniques and ships except the periods of cloudy and stormy weather. For continuous monitoring of the evolution of the zones of increased productivity the methods of mathematical modeling of processes in the sea are used. In this paper with the help of the local hydrodynamic model the mechanism of the production zone at the Goose bank in the Barents Sea is reproduced. It is shown that during the passage of a cyclone over the bank there is a destruction of the thermocline and flood, containing plant nutrients necessary for the organic synthesis.Keywordsprimary productivity, bioefficiency areas, hydrodynamic modeling, cyclone effectReferences
