Coccolithophore export production, seasonal species composition and coccolith CaCO3 fluxes in the NE Atlantic (34°N, 21°W and 48°N, 21°W).

Coccolithophores were examined in two sediment traps, deployed for one year (April 1989 to April 1990) at approximately 1 km water depth, in the subtropical NE Atlantic at 34 °N 21 °W (station NABE-34) and in the temperate NE Atlantic 48 °N 21 °W (station NABE-48) as part of the JGOFS North Atlantic Bloom Experiment (NABE). At both stations, maximum coccolith and coccosphere fluxes were recorded during local spring bloom periods. The average coccolith and coccosphere fluxes at NABE-34 were 1.12 x 1
