On the occurrence of the scyphomedusan Pelagia noctiluca in the English Channel in 1966

The oceanic scyphomedusa Pelagia noctiluca (Forskål) was exceptionally abundant in the coastal waters of Devon and Cornwall in the year 1966. Very young stages were taken only in the months of October, December, January and early February, indicating that the medusa has a restricted breeding season.

Monthly temperature-salinity diagrams for 1957 have demonstrated that three surface oceanic "water bodies" were consistently present in the eastern North Atlantic; two are regarded as modified North Atlantic Central water which give rise to the third by mixing. As well in the oceanic areas, large and small, high or low salinity patches of water were common. Effects of seasonal climatic fluctuations differed in the several oceanic water bodies. In coastal waters, differences in properties and in seasonal and annual cycles of the properties distinguish the waters from the North Sea, English Channel and the western entrance to the Channel.The geographic distributions of the oceanic waters are consistent with "northern" and "southern" water bodies mixing to form a "transitional" water. Within this distribution there are short-term changes in boundaries and long-term (seasonal) changes in size of the water bodies.Water in the western approaches to the English Channel appeared to be influenced chiefly by the mixed, oceanic transitional water; oceanic influences in the North Sea appear to have been from northern and transitional waters.

Bronze Age objects found in the English Channel off Salcombe, southern Britain, include an implement which has its normal home in Sicilian agriculture – perhaps as a plough shoe. The authors assemble and classify the objects and consider the web of exchange networks that brought the artefact from Sicily to Devon via France around the thirteenth century BC.

The distribution of Dodecaceria in northern Europe was found for samples borrowed from museums and other collections. Dodecaceria fimbriata was present in the coastal waters of mainland Britain and the Continent from the English Channel northwards. Dodecaceria concharum was only found in British mainland coastal waters and on the French coast at the western end of the English Channel. It was absent where salinities were below ~34%0. The two species were sampled along the Lothian and Borders coasts and the numbers of D. concharum fell with decreasing salinity as the Firth of Forth was approached. Dodecaceria diceria was found for the first time in the North Sea at depths of 100–200 m. The benthic salinity here is ~35%0.

Several previous authors have shown that the food of the mackerel, when in coastal waters, is of two different kinds, and that the fish adopts two distinct methods of procuring it. In the first place it feeds by a system of filtration upon planktonic organisms, and secondly upon prey of a larger character which is hunted by sight.

Concentrations of alpha- and gamma- hexachlorocyclohexane (Lindane) have been determined in the surface waters of the Humber, Thames, and Mersey estuaries, an area of the Dogger Bank, the English Channel, around the Channel Islands, from the last known positions of the lost container from the M.V. Perintis off the Cherbourg peninsula, the Baie de Seine and an area of the south-western approaches, which was used as a ‘control area'. Samples were extracted, cleaned-up and analysed at sea using high resolution capillary gas chromatography with electron capture detection. Two capillary columns of different polarity were used to aid in confirmation of residues. Levels of Lindane in inshore waters were generally low (<2ng dm−3) and declined rapidly, on moving offshore, to back-ground levels.
