Preliminary analysis of seismic data shows filling of the Hudson Shelf Valley from Cholera Bank. Suspended sediment studies are particu- larly important in the bight apex because of the large amounts of fine particles dispersed in the water by waste disposal operations. These particles are in addition to the fine sediments discharged from the Hudson River, other river mouths, and tidal inlets connected to coastal wetlands. Fine-grained sediment is also eroded from the sea floor during storms. Of immediate concern is sewage sludge which contains bacterial, viral, and heavy metal contaminants that adhere to fine sediment particles in the water column. The suspended fraction of dredge spoils is also probably similarly con- taminated. All of these fines are largely re- 297.
