Description 
Summary

The cruise consisted of five mesoscale towed CTD/fluorometer surveys to obtain hydrographical background and four 24 h intensive biological-chemical studies at an anchor station. During the mesoscale surveys temperature, salinity and fluorescence were measured and samples for phytoplankton analyses were taken from the depth of ca. 5 m with a flow-through system. During the anchor station studies CTD/fluorometer, turbulence, particle size distribution measurements were made and samples taken. Dominant hydrographical features were the sharp salinity front along the Finnish coast and cold upwelling filament originating from Estonian coastal zone. The cruise schedule and measurements are presented in Annex 1.
