Nannoplankton contents in regard to petrological properties of deep-sea sediments in the Canary and Cape Verde areas

Nannoplankton assemblages from Recent sediments of the deep-sea areas adjacent to the Canary and Cape Verde Islands are different. The distribution of nannoplankton is strongly related to the sediment type.The nannoplankton assemblage of the Canary Islands area, between the easternmost islands and Morocco, is influenced by the cold Canary current and also by continental-detrital sedimentation with reworked Cretaceous material.The samples from an area between the Cape Verde Islands do not contain reworked or cold-water species because of the shield effect of the islands. The material studied from the cores of both areas belongs to the youngest nannoplankton zone (Emiliania huxleyi zone, NN21).
