| Beach samples from the Belgian coast and the Nieuwpoort Channel have been examined for (a) coliform and other common bacteria and (b) more serious pathogens, to determine from their distribution the influence of season, tide, presence of human and other animals and of effluent. There were more coliforms in summer than in spring. State of tides had no significant effect on coliform numbers. The dry sand above HWM, occupied by holidaymakers, was as polluted as intertidal sand. Sand in the Channel near a sewage outfall was rich in coliforms. <i>Salmonella paratyphi </i> B was also found, but no <i>Shigella</i> spp., although <i>Shigella phages</i> were present. |

| An extensive program of tracer experiments was carried out for calculating sediment transport in the vicinity of the Port of Zeebrugge where extension operations are in progress. Offshore radioactive bottom tracers were used for studying the sand transport along the beaches where erosion problems exist. On the beach itself fluorescent tracers were used. For the evaluation of the silting-up rate of the access channels to the harbour a series of radioactive bottom and suspension tracers were tracked <i>in situ</i>. For determining the efficiency of future dumping grounds a combination of bottom tracers and suspension tracers was used. In total, 18 experiments with radioactive tracers were carried out and 9 with fluorescent ones. |

| Continuous seismic profiling using boomer, sparker or pinger sources has gained widespread use in marine site investigations. At a reconnaissance stage, a grid of continuous seismic traverses with adequate orientation and mesh size is able to yield a coherent picture of the structural conditions of subsurface, allowing the definition of areas of main prospective interest. In the early stages of detailed site investigations, seismic profiling forms an efficient tool for the planning of high-cost offshore drilling and penetration testing programs. Keys to success in seismic data acquisition are a matter of careful balancing and matching of source/receiver parameters with the marine and geological environment and with the geotechnical penetration/resolution... |

| During an intensive survey of the littorinid fauna of the Belgian coast, five species were recorded alive, viz. <i>Littorina littorea, L. saxatilis, L. obtusata, L. mariae</i> and <i>L. neglecta</i>. The latter two of these are new to the Belgian fauna, but they occur only in very restricted populations. <i>L. obtusata</i> shows a local distribution, whereas <i>L. littorea</i> and <i>L. saxatilis</i> are both very common. For each species occuring in Belgium, detailed information on distribution, habitat and polymorphism is provided. Finally some topics for further research are outlined. |

| The report provides information on the importance of Caridean shrimps in the food of juvenile <i>Trigla species</i> (gurnard), <i>Agonus cataphractus</i> (hook-nose) and <i>Liparis liparis</i> (sea snail) in the Belgian coastal waters, and gives some biometric data related to stomach content and composition. The results show the importance of Caridean shrimps, especially <i>Crangon crangon</i>, as a food source for perciform fish species in inshore waters. The records of the chameleon prawn, <i>Hippolyte varians</i> in fish stomachs and in trawl and grab samples are compared, and the actual knowledge on the distribution and abundance of this shrimp species is discussed. |

| Intense residual erosion attacks several sections of the Belgian coast. During the last decades this coast has been hit over several kilometers at Knokke, at Bredene-De Haan, at Lombardsijde, at Koksijde and at De Panne. A sequence of beach budgets shows the phenomenon and its importance and proves that different morphodynamic sections follow one another all along the rectilinear coast. The author ascribes every erosive section to an erosive megaprotuberans attacking the coast over a more or less long distance during a more or less long time span. He proves that such megaprotuberans develops gradually, that it is part of a cyclic macroprocess of coastal evolution that lasts several decades, sweeps the cost and whose aggressive phase is followed up by a... |

| Marine fouling causes economical problems. Fouling diminishes the efficiency of propulsion of the ships. It enlarges the cost in fuel. Another effect is the loss in time and money because it necessitates frequent docking of the ships. These organisms increase the corrosion of metal in seawater. The damage to the timber constructions by marine borers causes renewed change of the piles. Therefore information was given about the principal fouling organisms at the Belgian coast. Some biologic aspects of the fouling were reviewed as the biotic succession by the different communities, the relation of fouling growth to local environments, the vertical zonation and the settling behavior of larvae controlled by salinity, temperature and light. |

| Community structure and intertidal zonation of the macrobenthos on a macrotidal, ultra-dissipative beach were studied. On the beach of De Panne, Belgium, six transects perpendicular to the waterline (each with five stations) were sampled in September 1995 (summer) and March 1996 (winter). The 30 stations were distributed across the continuum from mean high water spring to mean low water spring in order to sample the macrobenthos at different levels of elevation. The 39 species found had total densities up to 5,500 ind m<sup>-2</sup> in summer and 1,400 ind m<sup>-2</sup> in winter. The highest densities were found in the spionid polychaetes <i>Scolelepis squamata</i> and <i>Spio filicornis</i>, the nephtyid... |
