Distribution of benthic foraminifera in surface sediments on the continental margin off North-West Africa, supplement to: Lutze, Gerhard F (1980): Depth distribution of benthic foraminifera on the continental margin off NW Africa.

The benthic foraminiferal populations along three traverses across the Northwest African continental margin were analyzed on the base of ca. 60 surface sediment samples. Depth ranges of 213 species were established and the main trends of vertical distribution are compared with those known from adjacent regions. Main faunal breaks occure at 100/200 m and 1000/1500 m depth of water. Some species show latitudinal distribution boundaries and the same applies to population density (standing stock), reflecting the regional distribution of nutrients supply by river discharge and upwelling processes. – High proportions of Bolivina test at the lower slope indicate extended downslope transport.
