| 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... |

| Samples of phytoplankton cultures and of suspended particulate matter from continental, brackish and marine waters were examined by HPLC for the monosaccharide content of their hydrolysable sugar fraction. Eight monosaccharides were currently assayed and their weight compared to HPLC-assayed chlorophyll a concentrations. With the exception of oligotrophic waters, these two variables are well correlated in the various prospected environments. Glucose was always the strongly dominant form, not only in fresh and brackish waters but also in marine samples with high phytoplanktonic biomass. If samples are compared on a salinity basis, only four monosaccharides showed significant differences in their relative concentrations, as a consequence of sampling... |
