| Using time series analyses, some physical parameters of the continental shelf waters of the Gulf of Guinea were examined. Analysis of coastal sea surface temperatures from Ghana and Ivory Coast, and offshore sea surface temperatures from the Gulf of Guinea clearly shows spatial and inter-annual patterns of cooling in coastal waters of West Africa. The behaviour of the decomposed trend of coastal and offshore sea surface temperatures, sub-surface: temperature measured at 100 m depth off Ghana and salinity showed that the observational period (1963-1992) could be divided into three climatic periods: the period before 1972, from 1972 to 1982, and the period after 1982. In the first period, sea surface temperature at both coastal and offshore areas and bottom... |

| Electricité de France (EDF) has asked Institut Français de recherche pour l'exploitation de la mer (IFREMER) to monitor the coastal marine environment and its living resources around nuclear power plants along the French coast. Started in 1974, these investigations were undertaken in the areas of Gravelines, Le Blayais, Paluel, Flamanville, and Penly; the objective is to detect any impact of the open-circuit water cooling system, as well as any differences in the marine environment itself. To examine this question, IFREMER has set up a program called Impact des Grands Aménagements (IGA). It has evolved according to the results obtained and now integrates the specificity of each site in a global program common to all. The nature and the problems of impact... |
