Sediment Mixing By Invertebrates As Shown By 85kr1, Dexter S. Haven, Reinaldo Morales-Alamo, John N. Krauter
Reports
In the event radionuclides are accidentally introduced into an estuary, many isotopes would become adsorbed on suspended particles of clay or silt; others would be incorporated into living cellular material (Caritt and Goodgal, 1954; Rice and Willis, 1959). Oysters and other filter feeders in these estuaries are capable of filtering from suspension large quantities of the suspended solids, as well as the larger living cellular material (Haven and Morales-Alamo, 1966a). Ingested material along with the associated radionuclides would be voided as compacted fecal strings or pellets (biodeposits). Many of these fecal pellets may be alternately suspended in the water mass …

Reports
Certain invertebrates are more efficient than others in filtering solids from suspension. An equal degree of variability exists among benthic invertebrates in their ability to mix biodeposits into subsurface sediments. As a result of these differences, the degree to which suspended particulate matter and associated contaminants may be deposited or mixed into sediments may in part depend on the species present, which in turn may be dependent on sediment type. A number of investigators have examined the relation between benthic animal communities and their limiting physical factors (Smith, 1932; Mare, 1942; Dexter, 1947; Holm, 1949; Stic~1ey and Stringer, 1957; Sanders, …
Inner Shelf Sediments Off Chesapeake Bay. Iii, Heavy Minerals, Bruce K. Goodwin, John B. Thomas
Inner Shelf Sediments Off Chesapeake Bay. Iii, Heavy Minerals, Bruce K. Goodwin, John B. Thomas
Reports
The heavy minerals in the sand sized fraction of 112 grab samples collected off the Virginia coast were analyzed for their variations in mineralogy. The main purpose was to characterize the heavy mineral suite and to delineate potentially important economic areas.

Inner Shelf Sediments Off Chesapeake Bay. I - General Lithology And Composition, Maynard M. Nichols
Reports
The sedimentary materials and bottom topography of more than 2400 square miles of the inner continental shelf floor north off the Chesapeake Bay entrance have been surveyed for potential mineral resources. Sediments consist of two principal types: (1) fine sand and (2) medium to coarse sand. The fine sand is grey-colored, subrounded, rich in quartz and relatively 11clean 11 and well sorted. The medium-coarse sand is typically iron-stained, rich in shell and poorly sorted. The fine sand covers inner parts of the shelf floor whereas medium to coarse sand covers seaward parts. Additionally, shell-rich medium to coarse sand occurs on …
