Modern electrometrical methods for geological and environmental baltic shelf and coastal zone studies.

The main objectives are the design, development and
manufacturing of a special electrometrical complex modelling
device for the geological and environmental study of the
baltic shelf and coastal zone.

Marine shelf and coastal zones are of particular interest and importance from scientific and practical points of view. Because of their strategic and important role, they require systematic and complex study covering many objectives including litho-stratography and the thickness of recent sediments; coastal topography and bottom relief; expansion of the saltmarsh tidal creek network; circulation and shelf sediments' transport; erosion and saluation related to natural or anthropogenic factors; elemental total (integrated) pollution of bottom sediments and shelf waters; hydrophysical properties (salinity, temperature, vector of current and so on); prospecting of technical subjects on the bottom. Shallow shelf (0-15 metres) and coastal marine zones are rather difficult (sometimes impossible) to study using conventional techniques in open sea conditions, because they are usually shallow, have strong currents and are often inacessible to marine class vessels, so small boats and amphibian type carriers are more appropriate here. Such a universal marine geology method as continuous shallow seismic profiling is not effective in the coastal zone or on the shallow shelf. Conventional techniques are moreover not effective for decision making on some special problems on the shelf (out of the coastal zone and in shallow places). These problems are: determination of heavy metals content in water and sediments; zones of submarine discharging; physico- chemical discovery and investigation barriers; search and identification of technogenic objects buried in the sediments (including shells and containers with extremely toxic chemicals) and so on. To solve the problems mentioned above, of more practical use are methods based on measurements of natural electrical field of different nature. At the present time there exists no apparatus or software which can be used for these purposes. All currently used techniques and apparatus including ion-selective electrodes, are not highly effective. To achieve the correct results it is necessary to make a great number of measurements and also take into account a different outside measurement system designed on the principle of two level structures (such as temperature, salinity, pH-factor, etc.). All this is impossible without the use of modern computer technologies. So, the main aim of this project is the creation of the apparatus which will make it possible to carry out complicated complex measurements not only of electrical values but also of different hydrophysical, hydrochemical and various other parameters. This apparatus requires the creation of new, improved old software as well as a mathematical, methodical and interpretation device. Analogues of the suggested apparatus are absent. The novelty of this project lies with the creation of a principle new complex system, which will enable the whole volume of the above-mentioned problems to be solved. The cooperating partners in the basic research are: RUSSIA: "ecological company" IABI/EKOMP LTD., St.Petersburg FINLAND: TERRASOLID COMPANY LTD., Helsinki. EKOMP will act as the coordinator of the project and ensure that the results from the basic research investigations are used in this EUREKA project.
