La circulation superficielle dans la partie occidentale du Golfe de Guinée

Direct current measurements carried out for 10 years in the Gulf of Guinea clearly show the importance of transverse circulation. The general pattern of currents is characterized by an anticyclonic gyre. The seasonal variations of this circulation are calculated through the study of the 3-monthly averaged geostrophic currents. The biological consequences of such a circulation are outlined.

Circulation dans la partie orientale de l'Atlantique sud

The authors studied the circulation in the South Tropical Atlantic from hydrology and current measurements made during a cruise of the N.O. Capricorne in Nov 1971. Direct current measurements confirm the existence of the eastwards South Equatorial Counter-Current. The authors discuss the counter-current as confirmed by current measurements and high salinity core.

On the corals of the Nhatrang bay in Vietnam, eight new species of Hapalocarcinidae have been discovered. This paper gives a brief description.

Supplement a la Note (partie B): Récentes variations de température et de salinité de Nha-trang

The present reexamination of oceanographic stations data done in 1957, by graphics, aims to complete necessarily the part B of the last note of the author

Sur quelques especes rares de Brachyures (Leucosidae) de l'Indo-Pacifique (2è partie)

In the first part, some rare samples of Leucosidae, belonging to the collection of Nhatrang Institute of Oceanography, have been studied; some of them are included in the subfamily Ebaliinae. This note examines various species of this subfamily which were not described in the previous study.
