Denitrification and anammox are the major nitrogen-removal pathways in the water column and sediments in the Baltic Sea, yet denitrification rates are usually higher than anammox rates. Both processes depend on oxygen availability. Recently, it has been postulated that the nitrogen-removal via sedimentary denitrification is not high enough to balance all nitrogen inputs. The situation might become worse if the extension of the anoxic bottom areas continues. It is unknown whether the pronounced increase of water column denitrification will be high enough to compensate for the reduction of nitrogen-removal via sediments. As denitrification depends on the substrate availability, water column denitrification will change seasonally due to the variable supply of e.g. organic matter, iron, sulphur compounds, etc. Denitrification and anammox are mediated via bacteria. However, it is not well understood how the seasonal activity of the microbial communities affects denitrification and anammox. The general lack of comprehensive studies towards understanding the nitrogen-cycle has hindered our comprehension of the marine ecosystem functioning.

The main goal of the doctoral dissertation will be to investigate seasonal variability of the water column and sediment denitrification and anammox in the Baltic Sea.

Tasks description:

1. Conducting incubation experiments to characterize the seasonal nitrogen-removal (N-removal) processes rates in the water column and sediments of the Baltic Proper.

2. Determination of N-budget for the Baltic Proper.

3. Preparation and conducting fieldwork, participation in research cruises in the Baltic Sea.

4. Performing statistical analyzes and interpretation of the obtained data.

5. Preparing scientific articles.

6. Preparation of conference speeches and participation in national and international scientific conferences.
