Information × Registration Number 0211U007240, 0106U001408 , R & D reports Title Investigation of geophysical and biogeochemical processes determining stability and assimilation capacity of grate black sea ecosystem, for the management and creation of estimation methodology of marine environment quality popup.stage_title Head Eremeev Valery Nikolaevich, Registration Date 07-04-2011 Organization Marine Hydrophysical Institute NAS of Ukraine popup.description2 As a consequence the project realization a number of new methods of oceanographic descriptions determination and estimation of the state of marine environment is developed and inculcated in practice, particularly the most modern methods of the direct СО2 measurement and other inorganic forms of carbon; the row of the task-level geographic information system is created, such as the GIS Black Sea, including the subsystems of quality check of the data, and also providing of users by oceanographic information over the internet; the reference book of "Hydrooptical characteristics of the Black Sea" is prepared and published, containing aggregate data of optical researches of the Black Sea, since 1957; the electronic version of an atlas is created "Weakening of the directional light Index in deep-water part of the Black sea"; the presence of long-term changes of thermohaline structure of the Black Sea waters is shown and selected three steady 30-years-old periods of promoted/lowered vertical water stratification; discovered a change in character of atmospheric processes above the Black sea in 2002-2003 resulting in alteration of processes in marine ecosystem; joint analysis of theoretical results, information of the deep-water measuring in the Black Sea and laboratory experiments allowed to do the conclusion about the mechanisms of forming of the stationary state for a step differential-diffusive layer and build generalized a 1,5D unsteady-state model of vertical exchange in a stratificated pool taking into account unsteady-state external flow and geothermal stream of heat, the use of which allowed to get quantitative estimations of a budget of main biogeochemical components of the Black Sea ecosystem and to estimate the possible changes in the hydrochemical structure of waters in the changes of climate conditions and level of the total anthropogenic pressing; a method which allows to take into account influencing of spatio-temporal changeability of processes in a marine environment on the system "nutrients - phytoplankton - zooplankton - anchovy - a horse-mackerel - trade of anchovy and horse-mackerel" and possibility to design long-term changeability of commercial supplies of anchovy and spatio-temporal changeability of horse-mackerel fishing on the Black Sea north-western shelf in a warm period of year is shown.
