The Open Ocean Hydrofoil Ship: Will It Come Of Age?, Stephen W. Mcganka
The Open Ocean Hydrofoil Ship: Will It Come Of Age?, Stephen W. Mcganka
Marine Affairs Theses and Major Papers
Problems encountered during development of the hydrofoil ship have restricted exploitation of its unique characteristics in an open ocean environment. An examination of pertinent physical and technical constraints is undertaken to assess their impact upon the future. The focus of this examination is centered upon the evolution of the fully submerged foil type ship during the past decade with emphasis upon the commitment directed toward its development by the United States Government. The developmental process induced by this commitment is found to be impeded by physical and technical factors, but organizational and traditional constraints are also instrumental in retarding progress. …
The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning
The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning
Marine Affairs Theses and Major Papers
An analysis of the nature of multiple-use conflict on the continental shelf developed with particular emphasis on the involvement of ocean transportation and offshore oil recovery. The wide-ranging effects which offshore marine accidents may have on coastal residents is discussed. Trends indicate a growth in the level of conflict stemming from competition between those wishing to use the same ocean space for the same purpose, the same ocean space for different purposes, and different but related ocean space for incompatible purposes. Ocean transportation is identified as the single common element in all three conflict categories. Restriction on traditional concepts of …

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr
Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr
Fisheries Research Reports
Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.
The first Europeans to see the area were the exploring party led …
Consideration Of Macro-Climatic And Macro-Biotic Change In The Ozark Highlands During Post-Glacial Times, Kenneth W. Cole
Consideration Of Macro-Climatic And Macro-Biotic Change In The Ozark Highlands During Post-Glacial Times, Kenneth W. Cole
Journal of the Arkansas Academy of Science
Climatological, pedological and faunal investigations conducted in the Upper Midwest and the Ozark Highlands indicate that the environment to which man in the Ozarks was adapting over the past 12,000 years has undergone several major shifts, beginning with a cool-moist boreal forest situation followed by a period of warming and aridness resulting in prairie and deciduous forest climaxes and subsequently, in the last 4000-5000 years, change to the pattern reflected by present conditions.

Interpretive Potential Of South Dakota Wetlands, Douglas C. Harr
Electronic Theses and Dissertations
A study was initiated to devise a method for selecting prairie wetlands on which nature interpretation areas could be established. An evaluation form was designed to systematically identify areas of good potential and 64 prairie wetlands were evaluated. Twenty-two percent of the evaluated marshes were found to rank “excellent”: the method of evaluation was determined successful. A survey was initiated to determine visitor preferences for interpretive methods and facilities at an existing wildlife-interpretive trail. Seventy-nine percent of the visitors indicated preference for a self-guiding interpretive trail. Maps and pictures used in conjunction with self-guiding signs were deemed important. Ninety-one percent …

The Historic End Of Closed Seas, James Edward Grise
The Historic End Of Closed Seas, James Edward Grise
Marine Affairs Theses and Major Papers
The purpose of this paper is to consider the rather vague claims to closed seas by the Soviet Union and to determine what direction these claims are taking. The first part of the paper deals with the history and development of the closed seas concept and expands it into the present day claims in this area. It attempts to show how some of the past claims have remained over the years and how some of the others have progressed to claims of historic waters. In the final section an attempt is made to show some method for resolving some of …

Strategic And Related Considerations In The Development Of A Northwest Passage, Norman E. Larsen
Strategic And Related Considerations In The Development Of A Northwest Passage, Norman E. Larsen
Marine Affairs Theses and Major Papers
Environmental factors which have impeded activity in the Arctic, in the past, remain significant barriers to the development of the Northwest Passage. Consequently, enormous capital as well as bilateral planning and cooperation between United States and Canadian public and private agencies will be required if significant progress is to be achieved. The resource wealth of the Arctic promises the economic incentives essential to the eventual development of a transportation system to permit exploitation of these resources. Development of a commercially feasible Northwest Passage is both economically and strategically desirable. However, immense physical and engineering problems remain to be solved.

Annual Precipitation Regime Of Minnesota, Richard H. Skaggs
Annual Precipitation Regime Of Minnesota, Richard H. Skaggs
Journal of the Minnesota Academy of Science
Eigenvalues and eigenvectors computed on 30-year normals indicate an unusually high spatial homogeneity of annual precipitation curve shape in Minnesota. The generalized shape accounts for about 99 per cent of the observed variance and meshes well with the overall pattern of the central United States. Interesting deviations do occur, however. These deviations suggest fundamental questions about precipitation-causing processes which should be investigated in the future.

Petrography Of Xenolith Zones In The Black Face-Ames Plutons, Western San Juan Mountains, Colorado, Richard B. Moore
Petrography Of Xenolith Zones In The Black Face-Ames Plutons, Western San Juan Mountains, Colorado, Richard B. Moore
Theses and Dissertations
The middle to late Tertiary Black Face-Ames plutons are irregularly-shaped, intrusive bodies located in the San Miguel Mountains of southwestern Colorado. The Ames pluton is generally a composite sill; the Black Face pluton is an asymmetric laccol1th. The two plutons are probably joined at depth, and together they form a crudely annular outcrop pattern, open toward the west. The principal rock type within the plutons is granodiorite porphyry, although part of the Ames pluton consists of porphyritic rhyodacite.
Two major zones of xenoliths of Precambrian rock occur within the Black Face-Ames plutons; scattered xenoliths are found at widely separated locations. …

Computer Simulation Of The Hydrologic-Salinity Flow System Within The Upper Colorado River Basin, M. Leon Hyatt, J. Paul Riley, M. Lynn Mckee, Eugene K. Israelsen
Reports
Changes in the hydrologic equilibrium of a river basin resulting from resource development also produce changes in the quality pattern. Since the burden of quality maintenance must be shared by users (just as are quantities) predictions are needed for quality changes which might result from contemplated development at any specified location within the river system. This study reports the development of a computer simulation model of the water and salt flow systems within the Upper Colorado River basin. Because of the close relationship between the hydrologic and salinity flow systems, an understanding of the hydrologic system is essential to successful …
