Abstract
Measurements of dissolved and particulate Cd, Co, Cu, Fe, Mn, Ni, Pb a nd 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 prog ramme. These measurements have been integrated with data on fluxes of water and suspended particulate matter also obtained within the Fluxma nche programme to provide estimates of fluxes of these elements into t he southern North Sea. For Fe, Mn, and Pb, particulate fluxes are grea ter than dissolved fluxes, whilst the reverse is true for Cd, Cu and N i. Significant daily changes in magnitude of the modelled fluxes of wa ter through the Strait when combined with averaged metal concentration s over longer timescales, result in large changes of fluxes of metals on a day to day basis. However, relatively small changes are evident f or integrated autumn fluxes of metals for consecutive years using the available database. The annual fluxes of dissolved plus-leachable part iculate metals through the Strait of Dover relative to the most recent estimates of riverine and atmospheric inputs to the North Sea were in the order Cu (44%) > Cd (39%) > Zn (16%) > Pb (11%).
