Abstract : The relevance of suspended particle analysis to oceanography is discussed along with previous work done in this area. The limitations of the techniques used currently are presented. The author discusses the types of suspended sediments found in the ocean, presents a possible method for the determination of the relative concentrations of the types, and investigates a theory on particle sizing. The theory on particle sizing uses Brownian motion, an applied electric field and Mie scattering theory to determine a scattering function dependent on the size distribution of the suspended sediments. A derivation of the response time of the orientation of suspended particles in an electric field is presented which leads to a method for determining the relative concentrations of the suspended minerals.
