| 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... |

| 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... |

| 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... |

| 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. |
