Laboratory of Marine Ecology, Sozopol

The Laboratory of Marine Ecology is based in the town of Sozopol just on the coast of the Black Sea. Recently, it possess a permanent staff of three persons. It is provided with upgraded equipment and renewed laboratory facilities necessary for carrying out investigations on the biodiversity and functioning of the coastal marine ecosystems.


Research Topics:
  • functional monitoring of marine coastal ecosystems and wetlands;
  • anthropogenic impact assessment;
  • development of scientifically based management approaches of marine coastal zone and of wetlands ecosystems.
