| 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... |

| Measurements of dissolved and particulate Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn have been made on a regular basis over a fifteen month period at stations across the Strait of Dover, as a part of the Fluxmanche programme. These measurements have been integrated with data on fluxes of water and suspended particulate matter also obtained within the Fluxmanche programme to provide estimates of fluxes of these elements into the southern North Sea. For Fe, Mn, and Pb, particulate fluxes are greater than dissolved fluxes, whilst the reverse is true for Cd, Cu and Ni. Significant daily changes in magnitude of the modelled fluxes of water through the Strait when combined with averaged metal concentrations over longer timescales, result in large changes of fluxes of... |
