Assessment for ecosystem based management of marine environment on the basis of sea bottom and sediments
of the Gulf of Finland

 

Partnership:

Lead partner: Geological Survey of Estonia

Contact: Sten Suuroja s.suuroja....at....ctc.ee

 

Partners:

  • Institute of Ecology, Tallinn University
  • Marine Systems Institute at the Tallinn University of Technology
  • Institute of Geology at Tallinn University of Technology
  • Geological Survey of Norway

 

Background:

There is a lack of an adequate dataset on the seabed of the Gulf of Finland for evaluating and managing its state in reference with the ecosystem. A dataset exists from the 1980's and 1990's, collected during geological mapping of the seabed. These data contain information on seabed morphology of the Gulf of Finland, geology of seabed sediments and content of important environmentally hazardous elements. The data have not been digitalized or systematically organized, and are thus difficult to be compared with results of present measurements.

 

The Aim:

The aim of this project is to compile a data model on the seabed of the Gulf of Finland and its environmental state. This will form the basis for proposals on actions regarding monitoring and evaluation of changes in the state of environment.

 

Outcome:

Produced data layers will increase the awareness of decision makers, making possible integrated managing of the seabed of Gulf of Finland. In addition, this project provides scientifically-based evaluation results on the state of marine environment and on monitoring measures. These are helpful in developing plans for sustainable use of seabed, and thus further for gaining or preserving a good state of seabed ecosystems.

Role of TLÜ ÖI

Institute of Ecology at Tallinn University is responsible for carrying out geophysical measurements and takes part in diving works during the fieldworks Data collected by geophysical equipment will be analyzed and integrated into the central data model by our experts. Moreover, our laboratories are responsible for carrying out lithological analyses and analyses to determine the content of poly-aromatic hydrocarbons (PAHs) in the collected samples. Data will be analyzed by our experts and integrated into the central data model. We expect to establish knowledge base and elaborate methodological approach suitable for monitoring and evaluation of the environmental state of the sea bottom together with our partners.
