This book was released on 1977 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical model developed by Tetra Tech, Inc., which traces the movement of dredged material disposed in the aquatic environment has been employed at 10 proposed ocean disposal sites in the Hawaiian Islands. The primary objective of the model applications was to provide a qualitative description of the behavior of the disposed material with a corresponding estimate of how much of the material reaches the bottom of each of the 1000-yd-radius disposal sites. In addition to model results, a brief description of the numerical modle and the rationale for selection of the basic input data at the Pacific Ocean disposal sites are presented. Results from the study indicate that for the particular input data used, at most of the sites the majority of the material will leave the disposal site as suspended sediment rather than being deposited on the bottom.

Maragos and published by . This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of oceanographic studies conducted at deep ocean sites in Hawaii between 1976-1983 have revealed that ocean disposal of dredged materials has not had any significant adverse or long term impact on the marine environment in Hawaii. Impacts to the water column are only short term, confined to a matter of hours for each individual dump. The major water column impact is the temporary increase in suspended sediments and turbidity. The small volumes of dredged materials, the infrequent interval for disposal operations, and the relatively clean nature of the dredged materials further reduces the overall magnitude of impacts. Although the most significant impacts of disposal operations occurred to the benthic environment at the disposal sites, little long term adverse effects were noted and some beneficial effects may also have occurred. All of the deep ocean disposal sites in Hawaii are located in water depths in excess of 300m, and the benthic environment at these sites is well below the the photoic zone, thermocline, and surface mixed layer where most primary production is taking place. As a consequence, the primary sources of food to support the deep sea benthic ecosystems at the sites must directly or indirectly be carried down from shallow water, in the form of migrating fish and other nekton, drifting plankton, detritus, the carcasses of dead organisms, turbidity currents, etc. As a consequence, the biomass of the deep benthic communities is lower than what is observed in shallower water, lacking plants altogether.
