The Viability Of Imported Liquified Natural Gas As An Energy Resource, Richard L. Dick

Marine Affairs Theses and Major Papers

As the United States enters the 1980's, the need for secure and efficient energy sources is rapidly moving to the forefront of our foreign and domestic policies. It is apparent that our existence, as well as that of our allies, is closely tied to the ability to secure energy resources. The importation of Liquified Natural Gas (LNG), by specially designed ships, from oil exporting nations to energy consuming nations has been a highly touted energy resource. United States importation of LNG is not a cost effective energy resource due to: (1) dependence on foreign sources, (2) transportation costs including "hidden" …

Mouthpart Morphology And Feeding Strategies Of The Commensal Amphipod, Anamixis Hanseni Stebbing, James Darwin Thomas, George W. Taylor

Marine & Environmental Sciences Faculty Articles

The lack of the information on the biology of the commensal amphipod family Anamixidae prompted investigations into mouthpart ultrastructure, feeding biology, and host specificity of Anamixis hanseni Stebbing, 1897. Earlier investigators presented conflicting reports on the structural composition of the buccal region and feeding modes in anamixids. Scanning electron microscope analysis of A. hanseni showed a complete set of mouthparts to be present, although much modified and reduced, except for the well-developed maxilliped palps. Feeding is not parasitic (piercing and sucking host tissue) as previously believed but is accomplished while A. hanseni rests inside its host. Minute food particles are …

The Effect Of Deep Sea Bed Mining On Strategic Minerals And National Security, Gary R. Hammond

Marine Affairs Theses and Major Papers

Deep sea bed mining has been a topic of considerable debate since it became technically and economically viable as a mining venture in the mid 1960's. The availability of manganese nodules has been determined through costly "prospecting" operations and their existence in sufficient quantity and quality has been found to be adequate for the mining industry. Though the future of the nodule mining is undetermined, it is the purpose of this paper to determine its impact on the national management of its associated strategic minerals and national security.

Decision Analysis: A Systematic Approach To Environmental Impact Assessment, Richard E. Dodson

Marine Affairs Theses and Major Papers

The creation of the national Environmental Policy Act of 1969 was an explicit recognition by the congress for the need of a better management system to be used in environmental matters by all federal agencies. Section 102(2)(A) of the Act directs that a systematic, interdisciplinary approach be used in the planning and in the decision-making if the planned action may have an impact on the environment. While the council on Environmental Quality, which was created under the Act, has revised its regulations recently pertaining to the structure and format of Environmental Impact Statements (EIS), it has yet to articulate how …

Growth And Recruitment Of Two Penaeids In The Bay Of St. Louis, Mississippi During 1979, Teresa C. Heaton

OES Theses and Dissertations

Juvenile brown (Penaeus aztecus, Ives) and white (Penaeus setiferus, Linnaeus) shrimp were collected from two stations of a nursery area in St. Louis Bay Mississippi, during May to October, 1979. Periods of shrimp recruitment and growth were determined to discern whether the concurrent environmental variables of salinity and temperature had an influence on shrimp abundance and yield. Growth estimates were obtained from length frequency measurements of trawl samples taken over a 24-h period per month from each station. An analysis of variance of length versus the variables of sex, month, station, time of day, salinity and …

Characteristics Of Sediment Transport In Overwash Surges, Paul Richardson Bowen

OES Theses and Dissertations

Sediment samples taken from a washover deposit were used to determine the mode of sediment transport within overwash surges. The determination of sediment transport mode is based on the concept of hydraulic equivalency of different density grains. Hydraulic equivalency may be based on settling velocities or entrainment velocities. Two individual mineral grains of different densities cannot have the same settling and entrainment velocities. If the settling velocities of each grain are similar, then the less dense grain must be physically larger to settle at the same rate as the smaller denser mineral. However, once both of these grains have made …

Seasat Altimetry Adjustment Model Including Tidal And Other Sea Surface Effects, Georges Blaha

Marine & Environmental Sciences Faculty Reports

This study is a part of the on-going effort aimed at improved determinations of the earth's gravity field through the adjustment of satellite altimeter data in the short-arc mode. Until recently the key role in such adjustments has been played by GEOS-3 altimeter data. However, SEASAT altimetry is envisioned as providing a more accurate means for addressing this task.

In view of the improved quality of altimeter data and of the corresponding more stringent requirements for the data reduction, several improvements in the existing altimetry model have been designed and are described herein. For example, the criteria have been established …

Comparing Three Water Quality Sampling Techniques For Measuring Non-Point Source Pollution In Forest Streams, R. Scott Beasley

Technical Reports

Coshocton wheel samplers, ISCO pumping samplers, and single stage samplers were compared on each of three small (5-6 ha), forested watersheds in the Ouachita Mountains of central Arkansas. The objective of the comparisons was to evaluate the performance of each sampling method in providing reliable samples for measuring concentrations of total suspended solids (TSS). H-flumes and water level recorders provided stream discharge data; a network of recording and non-recording raingages provided preciptation measurements. Rainfall and storm discharges during the study period were unusually low. No samples were collected by the single stage samplers. They appear unsuited for use on small …

Continental Shelf Processes Affecting The Oceanography Of The South Atlantic Bight. Progress Report, 1 June 1980-1 June 1981, Larry P. Atkinson

CCPO Publications

(Introduction) In the past year we executed our largest field effort to date, GABEX-1. The vast amount of data gathered has now been reduced to workable form and we report on some of the first results in this report. The GABEX-1 measurements combined with other observations in the last year have greatly increased our understanding of the South Atlantic Bight during the spring transition period when the shelf goes from horizontal to vertical stratification.

This progress report contains selected reprints, drafts, and parts of technical reports that represent our work over the past three years.

Temporal And Spatial Variations Of The Chesapeake Bay Plume, Evon P. Ruzecki

VIMS Books and Book Chapters

Historical records and data obtained during the Superflux experiments are used to describe the temporal and spatial variations of the effluent waters of Chesapeake Bay. The alongshore extent of the plume resulting from variations of fresh water discharge into the Bay and the effects of wind are illustrated. Variations of the cross-sectional configuration of the plume over portions of a tidal cycle and results of a rapid-underway water sampling system are discussed.

Aerial Spraying Trial., G A. Pearce

Experimental Summaries - Plant Research

Conclusions 1. The volume of application with water affected the results obtained. The visual results of Treatment 1 suggested it was not an acceptable commercial result and the plant counts support this conclusion. Treatments 2 and 3 looked very similar and were very similar and were very acceptable results. 2. The height of spraying affected the results in that where the plane had to start climbing to pass over trees, the effectiveness dropped off. 3. Spray drift could be a problem because of the risk of causing damage to trees and native vegetation. Severe damage was seen on trees at …

Geologic Investigations In The Cayman Trough And The Nature Of The Plutonic Foundation Of The Oceanic Crust, Janet B. Stroup

Geology Theses and Dissertations

A survey of the literature that deals with the gabbroic rocks believed to comprise the foundation of the oceanic crust indicates that the overwhelming majority of these rocks are recovered from escarpments associated with transform faults. The wide range of mineral and chemical compositions characterizing oceanic gabbroic rocks suggests that the lower oceanic crust is much more heterogeneous in nature than was previously suggested by the results of geophysical investigations. The examination of gabbroic rocks recovered in situ from the walls of the Mid-Cayman Rise rift valley by the submersible ALVIN not only supports the notion that oceanic gabbroic rocks …
