1. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling
Abstract : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. READ MORE

2. Biological, physico-chemical and biogeochemical dynamics of hydrophobic organ compounds
Abstract : This thesis presents new findings pertaining to several processes that govern the fate and effects of hydrophobic organic compounds (HOCs) in the environment. Two groups of HOCs, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), have been used as model compounds. READ MORE

3. Nutrient Dynamics and Exchanges Between a Mangrove Forest and a Coastal Embayment: Chwaka Bay, Zanzibar
Abstract : Nutrient dynamics and exchanges were studied in the Mapopwe Creek, a tidally dominated mangrove lined waterway, and a shallow lagoon in Chwaka Bay, Zanzibar, in order to assess whether there was any ecological coupling between the mangrove forest and adjacent ecosystems. In this study it was found that seasonal terrestrial input sources and benthic microalgal uptake strongly influenced the concentrations and distribution of dissolved nutrients in the system.

4. Benthic-pelagic coupling in a changing world : Structural and functional responses of microbenthic communities to organic matter settling
Abstract : Marine soft sediments form the second largest habitat on the planet. Organisms residing in this environment represent a vast reservoir of biodiversity, and play key roles in ecosystem processes. READ MORE

5. The role of sediments in nitrogen cycling in the larger Baltic Sea
Abstract : The eutrophication of coastal areas has become a widespread problem over the last decades. In the Baltic Sea, the input of nitrogen and phosphorus has increased by four and eight times, respectively, since the turn of the century, and this is considered the direct cause of the eutrophication of this ecosystem.
