Dissolved barium and nutrients in the Southern Ocean: their potential use as tracers for the characterization of the different watermasses
Description :
The location of the main Southern Ocean frontal systems, identified from surface water data for salinity and temperature during INDIGO 3, determines the surface water values for nitrate, silica and barium. For nitrate the strongest gradient coincides with the Subtropical Convergence (STC; 42°S). wi...

Influence of bacterial activities on nitrogen uptake rates determined by the application of antibiotics
Description :
The influence of bacterial activities on inorganic nutrients has always affected total phytoplankton uptake rates owing to the absence of a reliable method that can exclude these effects. The use of natural samples to determine the contribution of bacterial activities has been based on the size frac...

Phytoplankton nitrogen nutrition in the western Indian Ocean: Ecophysiological adaptations of neritic and oceanic assemblages to ammonium supply
Description :
The nitrogen nutrition of the phytoplankton community in the neritic and oceanic waters of the western Indian Ocean was investigated during the south-east monsoon (June-July) and intermonsoon periods (November-December). The region is very oligotrophic, characterized by very low nutrient concentrati...

Determination of methylmercury in biological samples by semiautomated headspace analysis
Description :
Gas-liquid distribution coefficients of methylmercury halides dissolved in water or benzene have been assessed by using a headspace injection system coupled to a gas chromatograph-microwave-induced plasma system. Vapor concentrations decreased in the following order: CH3HgI > CH3

Biogeochemical behaviour of Cd, Cu, Pb and Zn in the Scheldt estuary during the period 1981-1983
Description :
Cu, Zn, Cd and Pb have been analysed in suspended matter and water samples from the Scheldt estuary, collected during five cruises between May 1982 and May 1983. In order to evaluate the overall metal behaviour in the estuary, continuous longitudinal profiles of the total, the particulate and the di...

Effect of organic complexation on the behaviour of dissolved Cd, Cu and Zn in the Scheldt estuary
Description :
Samples from the Scheldt estuary have been assayed for dissolved Cd, Cu and Zn using differential pulse anodic stripping voltammetry, either as total (after UV irradiation) or labile concentrations. Under these experimental conditions, labile concentrations ranged between 51-65% of total Cu, 16-66% ...

A room temperature procedure for the manual determination of urea in seawater
Description :
Several earlier studies underpin the important role of dissolved organic matter and more particularly urea in phytoplanktonic nitrogen uptake fluxes. Generally, the determination of urea concentrations relies on the formation of an imidazolone-thiosemicarbizide complex, a complexation which requires...
