Observations 
Parameters

Phytoplankton taxonomic biomass in water bodies; Wind strength and direction; Raw fluorometer output; Nitrate concentration parameters in the water column; Phytoplankton taxonomic abundance in water bodies; Phosphate concentration parameters in the water column; Primary production in the water column; Salinity of the water column; Horizontal velocity of the water column (currents); Density of the water column; Silicate concentration parameters in the water column; Temperature of the water column; Raw suspended particulate material concentration sensor output; Turbulence in the water column

Instruments

Fluorometers; current meters; current profilers; CTD; CTD undulators; particle sizers; underwater cameras; microstructure sensors; discrete water samplers; autoanalysers; liquid scintillation counters

Description 
Summary

The cruise consisted of seven mesoscale towed CTD/florometer surveys to obtain hydrographical background and four 18 - 24 h intensive biological-chemical studies at an anchor station. During the mesoscale surveys, salinity, temperature and fluorescence were measured and samples for nutrient and phytoplankton analyses were taken from the depth of ca. 5 m with a flow-through system. At the anchor stations measurements/samplings of turbulence, CTD, fluorescence, nutrients, phytoplankton, primary production, particle size distribution and in situ particle distribution videomicroscopy were made. Special attention was paid on the deep chlorophyll maximum at the depth of ca. 30 m.
