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...

The determination of polycyclic aromatic hydrocarbons in seawater from the Fluxmanche transect (Dover Strait)
Provedor de dados: 5
Autores: Law, Rj; Whinnett, Ja.
Concentrations of a range of polycyclic aromatic hydrocarbons (PAH) were determined by means of coupled gas chromatography-mass spectrometry (GCMS). Water samples were collected, using a contamination-free sampling device, at two depths (Im subsurface and 3 m above the seabed) at each of the six stations established in the Dover Strait. The stations were occupied during June and October 1990, and July 1991. Concentrations of PAH were often close to or below the limits of detection for samples of 10.8 1 volume, although a number of samples exhibited high concentrations (of naphthalenes in particular) which were apparently derived from shipping inputs in the Dover Strait. Future work will require the development of methods with lower limits of detection, and...
