Upwelling of cold. saline, and nutrient rich water was observed in late September 1999 along an east-west transect in the SW Kattegat. The Kattegat forms part of the transitional zone between the high saline North Sea and the low saline Baltic Sea. The upwelling occurred after an extended period of northward flow and eastern winds in the Kattegat, that changed into a southward flow as wind ceased. The upwelling was the result of a combination of high current speeds and bottom topography whereby the high-speed inflow water was forced towards the surface at the slope. Nutrient data show that the upwelling brought nutrient rich bottom water to the light exposed surface and a related strong (1943.5 ml(-1)) bloom of Pseudo-nitzschia pseudodelicatissima was... |

This paper describes the changes in hydrography and the vertical distribution of suspended particulate matter (SPM) that occur during an inflow of highly saline water into a semi-enclosed bay. The study area is situated near the frontal zone in the Kattegat between the highly saline waters (32-34) of the North Sea/Skagerrak and the less saline waters (15-20) of the Baltic Sea. The water column at the frontal zone is stratified throughout much of the year. The study was carried out in a bay in the southwestern part of the Kattegat, and is based on CTD-observations, current direction and speed, and samples of suspended particulate matter obtained during the study period. The study shows that the hydrography of the bay is strongly influenced by the inflow... |
