Marret, F., 1994. Distribution of dinoflagellate cysts in recent marine sediments from the east Equatorial Atlantic (Gulf of Guinea). Review of Palaeobotany and Palynology 84 (1994): pp. 1-22. Abstract Suriace sediment samples of 46 sites from the eastern Equatorial Atlantic Ocean were analyzed for their palynological content in order to document the dinoflagellate cyst distribution in relation to oceanic parameters (sea-surface temperature, salinity and water depth). A total of 34 species were identified. The assemblages are mainly dominated by Brigantedinium spp., Spiniferites delicatus, Polykrikos kofoidii and Lingulodinium machaerophorum. Dinoflagellate cyst distribution seems to be more influenced by water depth and sea-surface salinity than sea-surface temperature. Other factors, such as the nutrient richness, seem to control the species distribution, notably that of Brigantedinium spp. and Polykrikos kofoidii. Moreover, high cyst concentration and abundant S. delicatus and P. kofoidii cysts characterize the upwelling system.
