A room temperature procedure for the manual determination of urea in seawater

Author(s) : Goeyens, L. , Kindermans, N. , Yusuf, M.A. , Elskens, M.
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...

Export production in the Bay of Biscay as estimated from barium - barite in settling material: a comparison with new production

Author(s) : Dehairs, F. , Fagel, Nathalie , Antia, A. , Peinert, R. , Elskens, M. , Goeyens, L.
Description : We present barium data for sediment traps deployed in a northeast Atlantic margin environment (Bay of Biscay). Fluxes of excess barium were measured with the objective of calculating carbon export production rates from the surface mixed layer and thus contribute to the understanding of organic carbo...

Spatial and temporal trends in nutrient concentrations in the Belgian Continental area of the North Sea during the period 1993-2000

Author(s) : De Galan, S. , Elskens, M. , Goeyens, L. , Pollentier, A. , Brion, N. , Baeyens, W.F.J.
Description : Statistical analysis of nutrient data obtained during 8 years of monitoring indicated strong seasonal and spatial variability, with highest concentrations in winter and significantly higher concentrations (on average >2 times higher) in the salinity zone S < 33 than in the salinity zone S = 33. ...

Particulate barium stocks and oxygen consumption in the Southern Ocean mesopelagic water column during spring and early summer

Author(s) : Dehairs, F.A. , Shopova, D. , Ober, S. , Veth, C. , Goeyens, L.
Description : Particulate barium was analysed in the upper 600 m of the Southern Ocean water column during repeated transects along the 6 degree W meridian in October-November 1992. The transects extended between the northern edge of the Weddell Gyre (57 degree 30'S) in the south to 47 degree S within the Polar F...

Improved estimation of f-ratio in natural phytoplankton assemblages

Author(s) : Elskens, M. , Goeyens, L. , Dehairs, F.A. , Rees, A. , Joint, I. , Baeyens, J.
Description : Statistical properties in non-linear regression models of f-ratio versus nitrate relationships were investigated using a case study conducted at the European continental margin (Project OMEX). Although the OMEX data fit within the family of empirical models introduced by Platt and Harrison (1...

Nutrient depletions in the Ross Sea and their relation with pigment stocks

Author(s) : Goeyens, L. , Elskens, M. , Catalano, G. , Lipizer, M. , Hecq, J.H. , Goffart, A.
Description : The present article depicts a first attempt to relate the governing nutrient uptake regime and phytopigment signature of the Ross Sea. Based on nutrient and phytopigment data obtained during two cruises in the Ross Sea, two distinct groups were recognised. The first one was characterised by moderate...

Stable pollutants in the eastern part of the North Sea

Author(s) : Baeyens, W.F.J. , Dehairs, F.A. , Goeyens, L. , Vandenhoudt, A.
Description : The spatial distributions of most dissolved and particulate trace metals are, at least qualitatively, similar. Their concentrations decrease with distance from the coast and the mouth of the Scheldt estuary (particulates much stronger than dissolved species). The salinity gradient is similar (but op...

Total and toxic arsenic levels in North Sea fish (poster)

Author(s) : De Gieter, M. , Leermakers, M. , Van Ryssen, R. , Noyen, J. , Goeyens, L. , Baeyens, W.
Description : Levels of arsenic contamination in muscle and liver tissue of 25 seafish and 4 shellfish species from the North Sea and the English Channel were determined. Analyses were done both by ICP-MS and HG-AFS in order to distinguish between the toxic fraction, consisting of As(III), As(V), MMA and DMA on ...
