During the JGOFS-France/Eumeli programme, biogeochemical processes governing particle fluxes throughout the water column were studied in the Eastern Subtropical North Atlantic Ocean. From February 1991 to December 1992, three consecutive sets of sediment trap moorings were installed at two sites: the mesotrophic site: similar to18degrees 30 N, 21degrees 00 W, and the oligotrophic site: similar to21degrees 00 N, 31degrees 00 W. Currents were measured at each sediment trap level (250, 1000 and 2500 m) in order to understand better the dynamics in this area and its influence on the particle fluxes through the water column and to monitor the current speed conditions during the particle trapping. The results of these current measurements are presented here,... |
