How Do Sediments Enter The Bay, Move Through The System, Remove And Store Chemicals, Or Release Them?, Maynard N. Nichols
How Do Sediments Enter The Bay, Move Through The System, Remove And Store Chemicals, Or Release Them?, Maynard N. Nichols
VIMS Books and Book Chapters
Escape of more than two million tons of sediment., 4,000 tons of man-made chemicals (e.g. Cd, Cu, Pb and Zn) and more than 300 types of synthetic organic compounds annually into the Bay, shoals shipping channels, reduces water quality and threatens biota. Where then do these enormous loads go? Are they mainly flushed into the sea or stored on the Bay floor? And what happens to chemicals attached to the sediments as they pass through different chemical regimes of the Bay? These are important questions facing scientists who aim to understand the cycling of sedimentary materials and to predict the …

Scientific knowledge of Chesapeake Bay and tidal tributaries has accumulated over many years beginning mostly with descriptive surveys prior to the 1960's and 1970's and evolving towards a coupling of monitoring and research in recent years. This essay discusses the need to more fully couple monitoring and research efforts in the Bay system because such a union of efforts is argued to be the most effective way to assess gross trends in the "health" of the system (monitoring) and to understand the basic forces causing these trends (research). We argue that together they provide part of the framework necessary for …
How Can We Best Test The Effects Of Pollutants And Changes On The Animals And Plants Of Chesapeake Bay?, L. Eugene Cronin, Morris H. Roberts Jr.

The animals and plants of the Bay, and the processes in which they are involved, are the basis for almost every use and desirable quality of the Bay. They provide both commercial and recreational fisheries, assimilate some quantities of wastes, contribute to esthetic quality, provide a favorable environment for many birds and mammals and feed all of the species which are used by man. However, the biota are directly or indirectly affected by many human activities - by maritime transport, recreational activities, agricultural production, waste discharges, domestic development, engineering activity, and other land-based activities. Therefore, the ultimate and most important …
What Are The Best Guidelines For Dredging And Placement Of Dredged Materials?, Maynard N. Nichols
What Are The Best Guidelines For Dredging And Placement Of Dredged Materials?, Maynard N. Nichols
VIMS Books and Book Chapters
During the~ next 25 years, more than 280 millicm cubic yards of sediment will be dredged from the Chesapeake Bay and its tributaries (Table 1). Altogether more than 800 million dollars will be spent to deepen ports and maintain shipping channels. About one-third of the maintenance dredgin~; will be done in ports and harbors where the sediment is contaminated by industrial wastes and sewage discharge. Because of long-continued disposal of dredged material, the region is losing its physical capacity to assimilate more material. Where then can these enormous loads be placed at acceptable costs? And what are the best guidelines …
