Loftet, Uppsala
Welcome to our workshop that aims to increase the participants' knowledge and network about the nitrogen cycle in the Baltic Sea.
Rapid climate and environmental changes challenge the health of the Baltic Sea ecosystem and our capacity to predict ecosystem responses. Eutrophication and its wideranging ecosystem effects is a key problem in the Baltic Sea that is driven by overavailability of nitrogen (N), as well as phosphorus. While N-research has gotten fair attention in the Baltic Sea community, we still lack a holistic approach bringing together data, experience, and knowledge across national borders.
The Baltic Sea Nitrogen Cycle Network (BSNCN) project aims to fill this gap by pooling the expertise on N-cycling from around the Baltic Sea to improve understanding and predictive power in the face of ongoing changes. The project is funded by the Swedish Institute.
With the aims of increasing our knowledge and building network around the Baltic Sea we are now hosting a workshop in Uppsala for everyone interested in nitrogen cycling related questions and issues. We will have keynote speakers, group and panel discussions, poster mingle, as well as meals and conference dinner, so that we can interact and build new bridges.
The conference is free for all participants, please register and upload the abstract via the link below. Please register as soon as possible to ensure your participation as seats may fill up.
A warm welcome to Uppsala in May.
