A two year record of downward particle flux was obtained with moored sediment traps at several depths of the water column in two regions characterized by different primary production levels (mesotrophic and oligotrophic) of the eastern subtropical North Atlantic Ocean in the framework of the EUMELI program. Settling particles were collected with multisample conical sediment-traps moored at 1000 and 2500 depths in the water column. Time-series samples were obtained between February 1991 and November 1992. During this time, sampling intervals varied from 8 to 10 d and were synchronized at all depths and also between the oligotrophic and mesotrophic moorings. Sediment-trap sampling procedures were consistent with JGOF and described elsewhere. The data shown here are mass, particulate organic carbon (POC), particulate inorganic carbon (PIC), coccolithophore, opal, and lithogenic downward fluxes obtained during the entire sediment-trap deployments at both sites.
