| During a comprehensive study of the macro- and meiobenthos of the Kwintebank, a sandbank in the Southern Bight of the North Sea, eleven female specimens of a cylindropsyllid, belonging to a new genus, were collected from one of the stations sampled. The station's coordinates are 51°18'00''N 2°40'10''E. The sediment at this stations is a pure, very well sorted, coarse sand (median grain size: 517 µm; sorting: 0.24; mud<63µm: 0%) with a harpacticoid community similar to the <i>Leptastacus laticaudatus-Paramesochra helgolandica</i>- community from the "Open Sea" Zone described by Govaere et al. (1980). All specimens have been deposited at the "Koninklijk Belgisch Instituut voor Natuurwetenschappen", Vautierstraat 31, B-1040 Brussels, under no.... |

| Nine heavy metals have been analysed in the liver, muscle and kidneys of sperm whales that stranded on the Belgian coast, November 18, 1994. The concentrations of most of the studied inorganic contaminants -except mercury and cadmium- were very low. The mercury content of the tissues was high, but in the range of those found in sperm whales previously described in the literature, as shown by Joiris et al. (this volume), and most of the mercury was found under an inorganic form. We found a close correlation between the mercury and selenium contents of the livers, which strongly suggests that the pollutant was detoxified under the tiemannite form, and therefore was not potentially toxic for the animals. On the contrary, cadmium was found in high... |

| The area of the North Sea next to the Belgian and Dutch coasts has been surveyed since January 1971. The photosynthetic capacity (potential production) of samples collected at 63 stations and 4 depths has been measured using the <sup>14</sup>C techniques. The homogeneity of the water column was demonstrated almost everywhere. A general pattern of decrease of the potential production from the coast to the open sea was demonstrated in all seasons. Figures ranged from 3 to 30 mg C m<sup>-3</sup> h<sup>-1</sup>. Primary production was also determined both by calculations, using the Steemann Nielsen (1952) formula, and by <i>in situ</i> measurements. The higher turbidity near the coast has proved to limit... |

| A joint seismic exploration programme, carried out in recent years by Belgian, British, French and Danish university laboratories in the southern North Sea and Schelde estuary, has revealed various styles of clay tectonics in Eocene and Oligocene deposits. In this paper particular attention is drawn on the remarkable deformation features observed in the Ieper or London clay, which forms the subsoil of the major part of the Thames estuary and the Belgian shelf sector. Those clay structures have eluded many previous investigations, mainly due to a lack of interfaces with large reflection coefficients. When however a seismic source is adequately tuned, the sum of reflection responses from the many subtle interfaces within the clay sequence may construct an... |

| Heavy metal concentrations in total particulate suspended matter and size fractionated particulate suspended matter above the Southern Bight of the North Sea have been assessed. Most of the samples were collected from a light vessel; the total sampling period covered about 70 days at sea. Stringent precautions were taken during sampling, storage, handling and analysis of the samples. As a conclusion, we found that on a long-term basis the aerosol concentrations above the North Sea have a fairly homogeneous composition, but short-term variations probably resulting from point emissions were observed. The cascade impactor results indicated that Pb, Cu, Cd and Zu were carried by submicrometer aerosols, Na, Fe, Mn and Al by supermicrometer aerosols. Most of the... |

| In this study we have investigated air-sea exchanges in the Belgian coastal area located in the Southern Bight of the North Sea. Since 1980 the tropospheric aerosol contents for the trace elements Cd, Cu, Mn, Pb, Zn and for the reference elements Al , Fe, Na have been monitored on an intermittent basis from a maritime sampling platform (Light-Vessel West-Hinder; position: 51°23.5'N- 2°21.5'E, fig. 1). During 1981 sampling campaigns at sea were paralleled by sampling campaigns on land, in the coastal area (natural reserve De Blankaert, located at 20 Km inland), in order to allow for a better evaluation of the specific source or sink role of the sea. No major source of pollution exists between the maritime and the continental sampling sites. During these... |

| The South Bight of the North Sea has been investigated for the photosynthetic capacity of net- and nannoplankton, the fractional filtration method being used simultaneously with the C14 technique. The water appeared to be well mixed so that no important variations occurred along the vertical profile. The horizontal distribution of net-/nannoplankton ratios showed, however, a zonation pattern with netplankton-dominant activity near to the coast and nannoplankton-dominant activity further off. The interference of the River Scheldt has also been demonstrated. The various implications of the 'metabolic structure' of the phytoplankton community demonstrated by the fractionation method are discussed. |
