The determination of polycyclic aromatic hydrocarbons in seawater from the Fluxmanche transect (Dover Strait) ArchiMer
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...

Aspects of the geochemistry of dissolved and particulate Cd, Cu, Ni, Co, and Pb in the Dover Strait ArchiMer
James, Rh; Statham, Pj; Morley, Nh; Burton, Jd.
Water column samples have been collected at six stations across the Dover Strait within the framework of the FluxManche programme every month for fifteen months and analyzed for particulate and dissolved trace metals. Important seasonal variations in trace metal distributions have been identified. Dissolved Cu and Ni exhibit similar behaviour in the Strait; while seasonal variation in their distribution may be determined by changes in freshwater input, additional processes including biological uptake and regeneration and benthic input probably perturb water column inventories. Consistently with the suggestion of other authors, Co and Mn in both the dissolved and particulate phase exhibit some degree of covariance; substantial increases in the concentration...
