the available BBL flow and particle and biogeochemical data of the Iberian margin (15 stations with u*c data, 3 stations with u*H data, 191 experimental ws measurements, 31 in situ ws measurements, «1200 aggregates analyzed), were used to determine the basic parameters for a simple particle transport model (Table 11.2). For a particle size spectrum from 50 to 4000 ^m in diameter, estimated excess densities, critical shear velocities, and critical deposition velocities decreased with increasing particle size, while the settling velocity increased over the same particle size spectrum.24
