Distribution of Suspended Particles in the Equatorial Pacific Ocean
Light scattering, size distribution of the suspended particles and standard hydrographic parameters were measured on water samples collected at 152 stations in the Panama Basin during October and November 1971. The particle-volume concentrations are calculated by fitting the measured particle size distributions to the exponential distribution and integrating the exponential distribution. Total suspended matter was calculated using a particle density of 2.2 mg/ml. The suspended matter in the water below 25 m depth ranges from 0.04 mg/l to 0.092 mg/l and from 0.11 mg/l to 1.76 mg/l in the sea surface.
The spatial distribution of the suspended matter appears to be closely related to the dynamic conditions of the water: the equatorial front, interaction of the Cromwell Current and the Galapagos Islands and interaction of bottom current against the Carnegie Ridge.
