During a research of a shallow brackish water sheet, the Dievengat, located on the territory of the region of Knokke, some copepoda were collected, amongst which three that had not previously been found in Belgium. The items originate from soil samples through means of a glass tube with a diameter of 6 cm²; it concerns a soil rich in detritus. The water is about 20 cm in depth at the location of the sample taking. Samples were taken over the period from August 1968 until May 1969. The salinity is susceptible to a relatively wide variation. Usually values between 12 promille S and 18 promille S were measured. The maximum measured was 19.03 promille S on 16/12/68 and the minimum measured 8.41 promille S on 5/5/69. According to the system of Venece, 1958, the... |

Belgium's Maritime Zone of Interest (BMZI), including the Belgian Territorial Sea, Belgian Continental Shelf, and Bonn Agreement Zone of Multilateral Responsibility, were regularly surveyed by remote-sensing aircraft for the presence of operational oil spills between 1991 and 1995. Simultaneously wind speed and direction were recorded; wave height was obtained from the literature. In total, 228 spills of various sizes, volumes and origins were analysed by means of univariate statistical analysis. We documented that the observed oil spills were generally elongate, narrow and thin, that spill dimensions were interrelated, and that wind speed and wave height affected these dimensions. A major fraction of the total variation however could be attributed to... |
