Within the framework of the European Fluxmanche programme, 92 samplings of suspended particulate matter were collected during eight cruises through the Dover Strait. The mean concentrations obtained for Al (44.3 mg/g), Fe (27.4 mg/g) and Ca (110 mg/g) are comparable to those obtained by Nolting and Eisma in January 1980. However, the concentrations of Mn (0.585 mg/g) Ti (3.14 mg/g) and V (0.225 mg/g) are twice as large. An important gradient of concentration is observed between the coastal and offshore waters, reflecting coastal erosion and human activities. Detailed examination of the contents of the major elements indicates that these remain practically constant in the particulate matter during a tidal cycle. On the other hand, the concentrations of...
