Abstract

Laboratory measurements were made of the sizes, shapes, and settling speeds of microscopic ocean-type particles by recording sequential transmission holograms of clay aggregates and glass shot in a settling chamber. Density values for particles that were approximate spheroids were determined using a modified Stokes settling equation. The successful application to this problem of inexpensive, off-the-shelf components and low power, He-Ne lasers improves the feasibility of remote, in situ measurements of ocean particle settling dynamics.
