High Value Fishery: Vessel-Harvest Helicopter Landing, Roger F. Scott

Marine Affairs Theses and Major Papers

The purpose of this paper is to examine the feasibility of using helicopters to move high value fish from the offshore fishing fleet at sea, to market distribution locations. To accomplish this purpose, data was collected on the high value swordfish species, ex-vessel, $1.50 per pound, and used to compare three basic options. Two Sikorsky helicopters were considered in the options tested; the light lift S58T, and the medium lift S61. The data shows the S58T to dominate the S61 in all comparisons. An underlying assumption of the analysis is that the fish landed by helicopter will demand a premium …

An Investigation Into A New England Fisheries Development Project: Towards The Expansion Of The Whiting Fishery, J. H. Kaelin

Marine Affairs Theses and Major Papers

In 1973, the New England Fishery Development Program (NEFDP), an industry/government partnership was formed to offset a portion of the economic decline of the New England fishing industry while encouraging the development of underutilized species and nontraditional fishery products. The purpose of this paper is to examine one of the NEFDP's development projects and to comment on its apparent success. This paper attempts to determine if domestic processors can be expected to produce whiting fillet blocks that can compete in the market place with foreign imports. Several aspects of the problem are favorably resolved-an abundant whiting resource is available; the …

Simultaneous Transport Of Water And 3hoh In Water, H. D. Scott

Arkansas Water Resources Center Technical Reports

Dispersion of ³HOH was studied at flow velocities less than 14 cm/day in a Captina silt loam using the half-cell technique. Two directions of transport were studied: movement of ³HOH in the same direction as water, and movement of ³HOH in the opposite direction to that of water. Results indicated that the dispersion coefficients were velocity dependent for equilibration times ranging to 21 hours. As the average pore flow velocity increased, the length of time needed for the dispersion coefficients to become independent of the flow velocity increased. When considering transport of ³HOH in the same …

Puerto Rico's Political Status And Its Right To A Territorial Sea And Exclusive Economic Zone, Sandra M. Laureano

Marine Affairs Theses and Major Papers

When, in 1973, preliminary seismic studies were made in Puerto Rico, in order to site a nuclear plant, possible hydrocarbon deposits were delineated. This gave rise to the controversy of Puerto Rico's right to its offshore resources. How far out does Puerto Rico's right extend? Puerto Rico's right to a territorial sea and an exclusive economic zone should be defined by international law standards. The controversy, in the context of Puerto Rico's status question, is what this paper is about.

Ward V. Coleman, Cert. Granted (Sub Nom. United States V. Ward): A Fifth Amendment Problem In The Enforcement Of The Federal Water Pollution Control Act, Mark Cohen

Marine Affairs Theses and Major Papers

On March 23, 1975 oil leaked out of an oil retention pit at a drilling site owned by L.O. Ward. Ward was an Oklahoma wildcatter and the owner and operator of L.O. Ward Oil and Gas Operations. The spilled oil ran down a gully and into Boggie Creek. Boggie Creek is a tributary of the navigable Arkansas River. The discharge of oil from Ward's property therefore amounted to the discharge of a harmful quantity of oil within the meaning of Section 1321 (b)(3) of the Federal Water Pollution Control Act and also a harmful quantity within the meaning of regulations …

Eleven trials utilizing buoyed drogues were conducted in the time frame February to October, 1979. Four trials were interrupted when buoys entered neighboring channels or dispersed too far for tracking, so that a total of sixteen runs were completed on the eleven trial …

Filtration Ingestion And Assimilation Rates Of The Mysid Shrimp Neomysis Americana Smith, Fed Three Food Sources, Robert W. Grabb

OES Theses and Dissertations

Laboratory grazing and assimilation experiments were conducted on the mysid shrimp Neomysis americana in an attempt to assess the suitability of three potential food sources. It was hypothesized that the smaller size classes were primarily herbivores, not becoming omnivorous until attaining lengths of approximately 5-6 mm. Four size classes of mysids from the summer generation, juveniles, immature, adult males, and adult ovigerous females were each fed three concentrations of Artemia salina nauplii, the rotifer Brachionus plicatilis, and the diatom Coscinodiscus lineatus. The mean lengths of the size classes utilized, plus or minus one standard deviation, were 2.5 …

Distribution Of The Dinoflagellate Symbiosis In Astragia Danae As Affected By Light Attenuation, Michael Perry Weston

OES Theses and Dissertations

Spatial zonation of symbiotic and aposymbiotic forms of the temperate coral Astrangia danae provides evidence that light attenuation is an important factor in the distribution of this animal. At four locations in the lower Chesapeake Bay and adjacent offshore waters, symbiotic colonies were observed only in well illuminated surface waters, while aposymbiotic colonies were observed in less illuminated deeper waters. A transition zone exists in which both colony types are found. Colonies on substrates forming a plane parallel to the sea-surface receive a greater radiant flux than colonies on vertical substrates. This extends the depth range of symbiotic colonies located …

Macrobenthic Communities Of An Industrialized Seaport Ecosystem: The Southern Branch Of The Elizabeth River, Virginia, Steven D. Hawthorne

Biological Sciences Theses & Dissertations

Macrobenthic invertebrates of an industrialized seaport ecosystem were studied seasonally from October, 1977 through July, 1978. Five stations were selected along the Southern Branch of the Elizabeth River, Virginia. The stations ranged from an area of heavy industrialization to a non-urbanized environment. At each station, bottom water was measured for salinity, temperature, dissolved oxygen, and pH. Within each sampling area, macrobenthic infauna! invertebrates were collected from in and out of channel sites along with sediment samples for various types of physicochemical analysis.

Community structure was spatially homogeneous at station sites and throughout the stations along the River. Slightly acidic pH …

Evaluation Of Possible Temperature Fluctuations From Proposed Power Modifications At Hoover Dam, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service

Publications (WR)

There are several planned alternatives for increasing the generation capacity of Hoover Dam to help meet peak power demands. These alternatives include: (a) uprating the existing generating units, (b) replacing or adding one or more generating units and (c) adding reversible pumped-storage hydroelectric units. Since the existing generators are at the end of their economic life and have to be replaced, their uprating has been scheduled as routine maintenance. This will increase the generating capacity of the Hoover Dam powerplant from 1240 MW to 1810 MW, but the anticipated capacity for meeting power demand is 2300 MW. Therefore, modifications (alternatives …

Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service

Publications (WR)

The U.S. Water and Power Resources Service is considering reregulating Lake Mohave water levels to increase the net power benefit from Hoover Dam. Reregulation will not increase the generation capacity of the Hoover powerplant but it will enable the plant operation to be increased when the energy has greater monetary value. Energy generated at different times of the year has different market value, the highest being in January-March and July- September. By generating more power during these periods more net monetary benefit can be derived from Hoover Dam. The total volume of water released from Hoover Dam over an annual …

An Analysis Of The Irreversible Thermodynamics Model For Coupled Heat And Moisture Transport Phenomena In Unsaturated Porous Media, J. A. Havens

Arkansas Water Resources Center Technical Reports

The Irreversible Thermodynamics-based model for the description of coupled heat and moisture transfer, attributed to Cary and Taylor, was analyzed. The transport coefficients appearing in the model equations were independently determined, and the equations were numerically integrated to predict temperature and moisture content profiles for a closed system of water unsaturated glass beads. An experimental investigation of the moist glass beads medium provided measurements of steady-state profiles of local temperatures and moisture content. These data, when compared with model predictions, indicated the validity of the Irreversible Thermodynamics approach. The coupling coefficient relating thermal gradients to moisture flux was found to …

Oil And Gas Development On Georges Bank: The Responsibility Of Federal Agencies For Assessment And Mitigation Of Potential Impacts On The Ecosystem, Carolyn A. Griswold

Marine Affairs Theses and Major Papers

Is it possible to provide adequate protection for the Georges Bank ecosystem as oil and gas exploration begins? The fishing industry and environmentalists say "no," but it is the resource managers who are faced with the task of predicting, assessing and mitigating impacts of development while at the same time managing resources and protecting fishery habitats. Much of this responsibility falls within NOAA; however, legislative mandates and agency responsibilities and goals mean that several other federal agencies are involved as well. This paper is an attempt to describe the potential impacts of oil and gas exploration on the Georges Bank …
