This publication is an up-to-date review of the papers published by the researchers of the Oceanographic Research Center of Abidjan, since its beginnings (1958-1978).

Stations cotières et station hydrologique cotière d'Abidjan années 1977, 1978 et 1979

On tables 1 to 12, daily beach surface temperatures are presented. These temperatures are also ploted on figures 2 to 5 in daily values and in 7, 15, 30 days means. Salinity variations are less important than these of temperature (Fig. 6, 7). It follows that during upwelling period, variations of dynamic height anomaly are closely correlated with temperature (Fig. 6 and 8).

Electrofishing survey of the River Calder and its tributaries - April 1978.

An electrofishing survey was undertaken in the period April 24th - 28th as part of the detailed biological study of the Calder Catchment being carried out by this department in early 1978. The sites to be fished were selected to indicate broadly the fishing status of the major sections of the main river and its larger tributaries and by no means intended to describe the fishing status of the whole catchment in detail. The results on the distributions of fish species are discussed, in general, in relation to the major polluting influences on the catchment. The results of the second survey are given and discussed separately in Appendix I.
