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.
