Simultaneous CTD and current measurements have been made repeatedly at several stations in a cross-section between the Danish island Laeso and the Swedish west coast. The cross-section is situated in the northern Kattegat, which forms the outer part of the Baltic estuary. Simultaneous nutrient and oxygen measurements were made in order to obtain a suitable set of background data for ecological modelling of the Kattegat. Here, this dataset is used to calculate fluxes of water, nutrients and oxygen, as functions of salinity. A striking feature is the much stronger inflow of high saline deep water during winter. While the inflow of oceanic deep water to the Kattegat occurs on the deeper western side of Laeso, the outflow of surface water from the Baltic seems to be dominated by the flux west of Laeso.
