Areas of research
3
Methodology Sonar map of the Rowy boulder area (coastal waters Stilo-Ustka) Batymetric map of the Rowy boulder area (coastal waters Stilo-Ustka) Selection of sampling sites: based on habitats delineated by experts using sonar and bathimetric maps
4
Methodology Sampling of benthic flora and fauna: -scuba diver -DAK, van Veen grab -video and photo documentation -type of sediment -% vegetation cover Samples preservation: - benthic flora - frozen - benthic fauna - preserved in 4% formaldehyde solution Analyses: - qualitative - species composition - quantitative: flora - dw·g/m 2, fauna - ww·g/m 2, abundance DAK device for collecting biological samples
5
Baltic habitat classification Classification based on: Species composition Biomass Type of the sediment % vegetation cover Photos and video films

Tasks to do for Department of Ecology 3.2.3.1. (9%) 3.2.3.1 Model for identifying the habitats of PMA in reference to EUNIS classification and the results of methodology studies. (9%) 3.2.3.4 3.2.3.4 Developing maps of the coastal water habitats from Stilo to Ustka. Vector map of habitats. (10%) 2.1.5 Determining the elements and processes that characterize habitats for biological and socioeconomic valorization. Methodology instructions.(18%)
17
Criteria of natural valuation of marine water areas ElementsCriteria Benthic flora presence of macrophytes (sandy or stony sediment) - biomass of each taxon (angosperms, macroalgae) Underwater meadows (habitats for fauna) - ratio of Angiosperms biomass to benthic flora biomass Presence of species used in restoration of degrated water areas - Ratio of protected/endangered species biomass to benthic flora biomass Trophy state - % biomass of Pilayella and Ectocarpus in total benthic flora biomass Benthic fauna Biomarkers Species richness/ diversity Abundance of oppurtunists Dominant species Community trophic structure
18
Problems to be disscussed 1.Energy levels in the Baltic Sea. 2.Adding new habitat classes to EUNIS classificaton: -mosaic sediments -offshore habitats, e.g. Słupsk Bank boulder 3. Criteria for natural valuation
