The Baltic Sea Science Congress was held at Rostock University, Germany, from 19 to 22 March 2007. In the session entitled "Upwelling events, coastal offshore exchange, links to biogeochemical processes" 20 presentations were given, including 7 talks and 13 posters related to the theme of the session. This paper summarises new findings of the upwelling-related studies reported in the session. It deals with investigations based on the use of in situ and remote sensing measurements as well as numerical modelling tools. The biogeochemical implications of upwelling are also discussed. Our knowledge of the fine structure and dynamic considerations of upwelling has increased in recent decades with the advent of high-resolution modern measurement techniques and modelling studies. The forcing and the overall structure, duration and intensity of upwelling events are understood quite well. However, the quantification of related transports and the contribution to the overall mixing of upwelling requires further research. Furthermore, our knowledge of the links between upwelling and biogeochemical processes is still incomplete. Numerical modelling has advanced to the extent that horizontal resolutions of c. 0.5 nautical miles can now be applied, which allows the complete spectrum of meso-scale features to be described. Even the development of filaments can be described realistically in comparison with high-resolution satellite data. But the effect of upwelling at a basin scale and possible changes under changing climatic conditions remain open questions.
