Arctic Marine Terminals -- Some Environmental And Engineering Considerations, Robert L. Mccollom Jr., William W. Moore Jun 1971

Arctic Marine Terminals -- Some Environmental And Engineering Considerations, Robert L. Mccollom Jr., William W. Moore

UMR Journal -- V. H. McNutt Colloquium Series

Studies are presently underway to determine the technical and economic feasibility of various Arctic marine transportation systems, including ice-breaker super-tankers and submarine tankers. An important consideration in these studies is the design and construction of marine terminal facilities which will be suited to the unique problems of the Arctic. Factors which will significantly affect the design of proposed marine terminals include:

1) bathymetric configuration of the continental shelf;
2) influence of moving pack ice on artificial structures, both at the air-water interface and along the bottom;
3) lateral and vertical variations in soil conditions, including residual permafrost, which might adversely …


Consideration Of Macro-Climatic And Macro-Biotic Change In The Ozark Highlands During Post-Glacial Times, Kenneth W. Cole Jan 1971

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.

A Comparative Study Of Nickel Sulphide Deposits Within The Area Of The Canadian Shield, Robert G. Kreiner Jan 1970

A Comparative Study Of Nickel Sulphide Deposits Within The Area Of The Canadian Shield, Robert G. Kreiner

Theses and Dissertations (Comprehensive)

In order to plan the future development of the Canadian Shield within a conceptual framework as suggested by the Mid-Canada Corridor concept, both the presently developed and potential, natural resources of this area need to be evaluated for knowledgeable development and management. To this purpose, various areas of nickel sulphide deposits within the area of the Canadian Shield have been studied with the object of determining similar sequences of intrusive events and their spatial relationships.

Within the Sudbury area, Ontario, five periods of intrusive activity have been recognized, each period characterized by an initial intrusion of acidic composition, followed in …


Beach Erosion Control Study On Duval County, Fla, U.S. Army Engineer District, Jacksonville Corps Of Engineers Nov 1964

Beach Erosion Control Study On Duval County, Fla, U.S. Army Engineer District, Jacksonville Corps Of Engineers

Waterways and wildlife

The purpose of this study was to define the beach erosion and the hurricane-induced flooding problems in Duval County, to determine the most economical methods of alleviating those problems, and to determine the division of costs between the Federal Government and local interests .


Studies In The Geomorphology Of The Mountain Regions Of The Upper Indus Basin, Kenneth Hewitt Jan 1962

Studies In The Geomorphology Of The Mountain Regions Of The Upper Indus Basin, Kenneth Hewitt

GreyZone

The investigation primarily concerns contemporary geomorphological features and processes in the Upper Indus Basin, Past work, and theories of the denudation chronology of the region are described, and the broad climatic and geological setting. The bulk of the work examines characteristics of weathering, slopes and mass-movements, glacial and fluvial features in the Biafo Gyang area of the Central Karakoram. The nature and role of glacier surges and natural damming in the region are discussed. An effort is also made to support the central theme with background information and visual illustration not normally available, and a comprehensive regional bibliography is provided. …


A Petrographic And Environmental Study Of The Upper Cretaceous Greenhorn Limestone, New Mexico, John W. Emerson May 1961

A Petrographic And Environmental Study Of The Upper Cretaceous Greenhorn Limestone, New Mexico, John W. Emerson

Earth and Planetary Sciences ETDs

The Upper Cretaceous Greenhorn Limestone is composed of intercalated agrillaceous limestone and calcareous shale beds which crop out over much of the Western Interior. The Greenhorn was deposited in late Cenomanian and early Turonian time in a westward transgressing sea. In New Mexico the age is early Turonian. The edge of deposition extends as far south as Capitan and Carthage, northward through western Bernalillio County, and northwest through Toadlena.


The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr Jan 1930

The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr

Yale School of the Environment Bulletin Series

Most of the field work has been conducted at the Aleza Lake Forest Experiment Station, in the valley of the Upper Fraser River, near the city of Prince George [British Columbia].

I. A series of twelve permanent plots (numbers 1 to 12) was established for the purpose of studying the occurrence of natural reproduction on various types of seed bed, under different densities of overwood and on northern and southern aspects. 2. A second series of four plots (numbers 17 to 20) was laid out in logged-off land for the purpose of studying the survival and growth of advance reproduction …


Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig Jan 1929

Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig

Yale School of the Environment Bulletin Series

This paper presents a study of the correlation between soil colloidal content and soil productiveness and hence a measure of the value of colloidal content in determining site quality. The character of this investigation also permitted incidental observation and comment on the relative value of organic matter, soil acidity, and soil type and class as similar measures. The findings are directly applicable to the forest soils of southern Connecticut and, more particularly, to such of these soils as occur commonly in the vicinity of New Haven. Since these soils are typical of the brown, weakly podsolized forest soils of southern …


Some Aspects Of Soil Moisture In The Forest, Ian J. Craib Jan 1929

Some Aspects Of Soil Moisture In The Forest, Ian J. Craib

Yale School of the Environment Bulletin Series

By determining the moisture content of carefully selected soil samples taken at various depths down to three feet, the moisture content of soils in the forest and in the open have been compared. The soils investigated were similar in their mechanical properties. Part I is an investigation of the effect of forest cover on the amount of water in the soil over the growing season and its availability. Part II is an investigation of the effect of root competition on the available water supply of forest soils.
