“…The existence of flocs in the marine environment has been observed by Bertbols [-1961], Biddle and Miles [1972'], Gibbs et al [-1983], Kranck [-1975Kranck [- , 1979, Krone [1962], Schubel and Kana [1972], Sheldon [1968'], and Zabawa [1978]. The settling velocity of particles in the ocean has been discussed by many investigators [Bishop et al, 1978;Carder, 1979• Hawley, 1982Kajihara, 1971; Kawana and Tanimoto, 1979• Letman et al, 1974• McCave, 1975McCave and Swift, 1976;Shanks and Trent, 1980]. These studies dealt with a widely diverse population of particles;many discuss biologically produced particles.…”

The size and settling velocity of flocs of suspended sediments from the Chesapeake Bay were measured in laboratory experiments and in the field. The curves between floc diameter and settling velocity showed a non‐Stoke's relationship that was best described by the following: settling velocity (cm/s) = 1.73 (floc diameter, cm)0.78. Furthermore, the relationship between floc diameter and settling velocity indicated that the floe density decreased as the floes increased in size. In addition to changing density, a cylinder shape was found to be the best shape factor.

“…A simple Stokes Law calculation relating size and density indicates the coarser particles would require a density of 1.26 g cm-3 to settle at the same rate as a denser (2.4g cm-j) fine inorganic fraction. Kawana & Tanimoto (1979) also noted that the largerparticles in suspension in Osaka Bay, Japan were of low density. We contend that the increased 'coarse' component seen during the winter represented an 'organic' pulse of relatively large size, but with low density and settling velocity.…”

The concentration and composition of suspended particulate matter (SPM) were measured weekly for a period of one year in the flood front waters traversing a muddy tidal flat. SPM concentrations were lowest in the winter when portions of the tidal flat were covered with ice, and biological activity was minimal. In contrast, the summer months had the highest SPM concentrations which reflected increased bottom resuspension. The two main sources of SPM were suspended matter carried in from offshore on the flooding tide and resuspended in situ bottom sediments. The offshore source was characterized by low SPM concentrations, coarse textures, and a high content of protein and chlorophyll ‘a’. Samples taken during resuspension events (storms/showers) had high SPM concentrations, finer textures, and were enriched in dead detrital organic material (phaeophytin). At any one time the SPM was primarily an admixture of these two sources. The highest SPM measurements were taken during storm events, with rainfall seeming to play a dominant physical role in aiding resuspension. SPM concentrations, textures, and compositions collected during the storms closely approximated SPM measurements made over newly dug ‘clam flats’.
