We present the first complete sections of humic substance fluorescence (HS fl )-values and total organic carbon (TOC) concentrations through the extended estuary of the Baltic Sea, Kattegat, and Skagerrak. Both HS fl -values and TOC concentrations co

The concept of interfacing open tubular liquid chromatography (OTLC) to electrospray ionization mass spectroscopy (ESI-MS) is here introduced. This combination has the potential of becoming a powerful and generic tool for separation and quantificatio

A method has been developed for determination of non-derivatised oligosaccharides by LC–MS at low concentration levels and in complex matrices of seawater and sediment pore water. Two ionisation techniques, dynamic fast atom bombardment (FAB)/liqui

In order to investigate the photobleaching potential of estuarine waters from different depths and redox conditions and with varying degree of biological activity, filtered, unfiltered and chloroform-poisoned water samples from the Baltic Sea were ex

The Black Sea is characterised by an oxic surface water layer and anoxic deep water rich in both hydrogen sulphide and methane, and in between a suboxic zone with very low concentrations of both oxygen and hydrogen sulphide. This makes the Black Sea

The Bosphorus Strait, which connects the Black Sea and Mediterranean Sea via the Marmara Sea, is characterised by two distinct water masses. The upper layer consists of low density Black Sea water (sigma-t 10-11) flowing southward, and it is underlai

Nitrification was studied in relation to the inorganic nitrogen species in the Skagerrak in May 1991 during the SKAGEX IV expedition. The distribution of density, ammonium, nitrite and nitrate are shown for the four north-south sections and, for two

A study of atmospheric deposited nutrients and some persistent pollutants has been carried out on the ice and snow fields of the subarctic Bothnian Bay, the northernmost basin of the Baltic Sea. Total amounts of 600, 500 and 400 tons NO3-N, NH4-N and

Two chlorofluorocarbons (CFC-11 and carbon tetrachloride, CCl4) widely used as tracers for dating water masses, were measured in the Gotland Basin of the Baltic Sea. At the time of the survey, the bottom water of the basin had remained stagnant for 1

The origin of bromoform in seawater and atmosphere, as well as possible sinks and breakdown mechanisms, is discussed. A bromoform budget is calculated for the Kattegatt area between Sweden and Denmark, where the input of bromoform from a power plant
