Temporal variability and composition of settling particle fluxes on the Barcelona continental margin (Northwestern Mediterranean)

摘要

The results of a year-long sediment-trap experiment provide the first direct observations of sediment fluxes to the seafloor on the Barcelona continental margin. Time-series of vertical particle fluxes, and major constituents (organic carbon, biogenic silica, calcium carbonate and aluminosili- cates) were determined inside and in the vicinity of the Foix submarine canyon from May 1993 to April 1994. The spatial and temporal variability of bi-weekly total mass fluxes indicate significant high .frequency variability related to physical and biological processes at this site.
