Climatic Implications Of Barbados Coral Growth, Richard E. Dodge, Karl K. Turekian, J. Rimas Vaisnys

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Results from a coral growth band analysis utilizing samples of M. annularis from the Recent Barbados reef and from three fossil raised reefs (Barbados I, II, and III dated at 82,000, 105,000, and 125,000 yrs. B.P.) indicate that in the Barbados II collection both average band width and variability were lower than in the other samples. We suggest the climate during formation of the 105,000 yrs. B.P. reef was significantly different than that of the present.

Interpretation Of Selected Soil Data From The Central Part Of Utah, Amjad T. El-Rihani

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Seventy-eight soil samples belonging to 15 sites were sampled by SEAM project in 1976. These 15 pedons represent different soil types which cover the Manti-LaSal area in the central part of Utah. The 15 pedons were described in standard notation. Complete soil analysis was done. The soil analysis includes the following determinations: particle size distribution, moisture retention, soil pH, organic matter, electrical conductivity, calcium carbonate equivalent, cation exchange capacity , base saturation, extractable cations and saturation extract soluble. Also x-ray diffraction for selected horizons was done.

The 15 pedons were classified according to the currently used system. This report includes …

The Intergovernmental Balancing Act: State-Federal Interests In Coastal Zone Management, Timothy M. Alexander

Marine Affairs Theses and Major Papers

The central notion of intergovernmental and inter-interest balancing suggested by the title of this paper reflects a distinctly American theme derived from our pluralistic, competing, compromissory and somewhat optimistic governmental values and experience. The Coastal Zone Management Act (hereafter CZMA or the Act) and the success of its implementation rests firmly on this balancing premise. The CZMA's assumptions, processes and implicit or stated objectives involve reliance on a governmental system that achieves effective and equitable intergovernmental balance.Yet, as I think this investigation will show, there are no ready-made answers as to how balance is to be achieved through the Act--let …

West Africa (East Central Atlantic) As A Regional Base For Fisheries Management, Conservation And Research: And Pollution Control, Vincent F. Adebolu

Marine Affairs Theses and Major Papers

About two decades ago when the First Law of the Sea Conference was underway, little attention was paid to ocean management. By then all of the ocean space apart from narrow bands of coastal waters was broadly recognized as the High Seas which is open to use by all countries. But despite this concept of free open use, only the major maritime powers were actually interested in maximizing the freedom of the seas principle. During this period there were only ninety independent coastal and landlocked states.

Rhode Island Coastal Zone Management And Local Government Organizational Structure: An Analysis Of Selected Community Governments, Methods, And Capabilities, Robert F. Greene

Marine Affairs Theses and Major Papers

It is the purpose of this discussion to examine the organizational structure, and the governmental processes selected Rhode Island communities utilize to carry out their particular role as participants in the management of the coastal resources within their political boundaries. Insofar as practicable, the major sources of information for this research are the communities themselves--their elected and appointed officials, and the documentary material the Towns generate and use as they carry out their management functions.

A Study Of The Second And Third Committees Of The Third United Nations Conference On The Law Of The Sea, James C. Bridgman

Marine Affairs Theses and Major Papers

The Third United Nations Conference on the Law of the Sea was divided along lines established for the preparitory Conference. The plenary consisted of all delegates of all delegations and was generally used to make formal what had already been negotiated in closed sessions. In the fifth session, it took on a new function as a forum for debating in closed session proposed articles on dispute settlement. In the future, it will look at drafts of the preamble and final clauses to the Convention. Each of three primary committees was empowered with specific issues to consider, again stemming from the …

A Proposal For Renewable Resource Management In Long Island Sound, Oliver T. Edstrom

Marine Affairs Theses and Major Papers

In the United States, prior to Public Law 94-265, the Fishery Conservation and Management Act of 1976, regulation of the harvest of oceanic fishery stocks was complicated by the principles of common property resource laws founded by Grotius' dissertation on freedom of the seas. Public Law 94-265 vests ownership in the right to manage stock of fish within 200 miles of the United States' coast to the United States as trustee of that fishery resource. Within the framework of extended jurisdiction of fishery management, individual states in the republic keep and maintain control of fishery resources. within their respective territories.

The Limnetic Zooplankton Community Of Boulder Basin, Lake Mead In Relation To The Metalimnetic Oxygen Minimum, Thomas A. Burke

Publications (WR)

The limnetic zooplankton community of Boulder Basin, Lake Mead, was examined to determine the role of this community in the development of a metalimnetic oxygen minimum which regularly occurs in the lake. Analysis of the community from May 1975 to April 1976 revealed that zooplankton maintain high populations within the metalimnion during summer stratification. The species composition of the community changes noticeably during the summer, but due to advanced stages excysting from resting forms, a complete assemblage of individuals are found throughout the 74 day period studied. Thermal stratification was weak, covering a 30 meter metalimnion. Eddy currents powered by …

Effect Of Nitrite And Nitrate On The Larval Development Of The Grass Shrimp Palaemonetes Pugio Holthuis, Carl Bingham Hinesman

OES Theses and Dissertations

The effects of nitrite and nitrate on survival and larval development of the grass shrimp Palaemonetes pugio were investigated in the laboratory. Nitrite concentrations assayed were 0 (control), 0.5, 1.0, 10, 25 and 50 mg NO₂/1. Nitrate concentrations tested were 0 (control), 100, 250, 500, 1000 and 2000 mg NO₃/1. Temperature and salinity conditions were 25 C and 25 ‰, respectively, and all tests occurred in the dark. Thirty-six larvae were reared in each assay, twelve from each of three adult females.

Nitrite levels of'5 and 50 mg NO₂/1 significantly reduced survival of larvae …

A Baseline Study On The Possible Mechanisms Of Larval Stomatopod Distribution On The Carolina Shelf, Carl Robert Berman Jr.

OES Theses and Dissertations

The South Carolina Marine Resources Institute provided the author with 198 station samples containing 2,193 stomatopod larvae. These larvae had been collected during ichthyoplankton Bongo tows on five separate cruises aboard the Institute's vessel R/V DOLPHIN (February, 1972 to January, 1975). The larvae were examined microscopically and divided into early, middle, and late stages according to known growth criteria. The larval distribution was plotted geographically, by seasons, and larval density (larvae/m3) was graphed against distance offshore. Using these data, together with the circulation characteristics on the Carolina Shelf, significant distributional data appeared which supported the hypothesis that the stomatopod population …

Temperature And Salinity Tolerance Of The Larvae Of The Sand Shrimp, Crangon Septemspinosa (Say), Karen Lyttle Hinsman

OES Theses and Dissertations

The effects of temperature and salinity on the larval development of the sand shrimp, Crangon septemspinosa, were investigated in the laboratory using 30 combinations of temperature and salinity in a five by six factorial experiment. The five temperatures were 5°c, 10°c, 15°c, 20°c, and 25°c and the six salinities were 10°/oo, 15°/oo, 20°/oo, 25°/oo, 30°/oo and 35°/oo. Thirty-six larvae were used for each temperature-salinity combination. Temperature and salinity produced significant differences (1% level) in survival and the duration of larval development. Highest survival occurred at 15°c and 20°/oo. At optimum temperatures (15°c to 20°c) larvae exhibited the broadest tolerance …

Successive Month Temperature Relationships For Twin Cities, 1820-1974, Charles J. Fisk

Journal of the Minnesota Academy of Science

Using a five category classification scheme of mean monthly temperatures, the long-term ( 1820-1974) relationships between Minneapolis-St. Paul successive months' temperatures were analyzed . Results show predominance of two-month persistence over two-month breaks in classification . Strong above norma11 and below normal persistence tendencies are revealed, particularly in summer and early fall sequences. In contrast, two month breaks in classification appear in spring and fall sequences. This emphasizes the uneven progression of warming (cooling) that occasionally occurs between winter (summer) and summer (winter). Overall, strongest month-to-month association was for August-September, weakest for April-May .

Landsat Linear Trend Analysis - A Tool For Groundwater Exploration In Northern Arkansas, H. C. Macdonald, Kenneth F. Steele, Elizabeth Gaines

Arkansas Water Resources Center Technical Reports

Intelligent development of groundwater resources is a process that requires a thorough understanding of the availability and movement of groundwater. In northern Arkansas knowledge of the deep aquifers is fairly limited, perhaps because economic factors and uncertain yields have discouraged exploitation. The development of these deeper aquifers to their fullest potential as reliable water sources depends on the delineation of high yield areas, a process that may be facilitated by linear trend analysis as outlined in this study. Satellite and photolineament maps of the 13 counties were prepared by use of LANDSAT images and Agricultural Stabilization and Conservation Service photo …

Distortion In Map Projections: Its Effect On The Interpretation Of Maritime Boundaries And Related Activities, Austin H. Gedney Iii

Marine Affairs Theses and Major Papers

Distortion inherent in map projections can effect the delimitation of maritime boundaries. Thirty-nine maps of three study areas representative of the world were drawn, and the envelope and median line offshore boundaries were constructed on them. Every country's enclosed boundary area was measure in each of the four categories of distortion; equivalency, conformality, equidistance and constant bearing. The result revealed a number of projections that indicate a wide range of usefulness depending on the degree of deformation and preservation of properties for a particular study area.

Fisheries Report No 27 - A Survey Of Recreational Usage Of South Coastal Estuaries Of Western Australia, N. Caputi, R C.J. Lenanton

Fisheries Research Reports

Over recent years, factors such as the State's population increase, a generally higher standard of living which enables people to have more leisure time, and better roads, particularly from the Eastern States of Australia, have all contributed towards an increase in the general recreational usage of the Western Australian south coast estuaries.

To aid proper planning of facilities to cater for an increasing number of visitors in these south coast estuaries, management agencies must be able to quantify the recreational usage in this group of estuaries.

This survey, therefore, attempts to identify and quantify the different recreational pursuits of visitors …

Lupin Trials, J Moore

Experimental Summaries - Plant Research

Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary.

Coral Populations And Growth Patterns: Responses To Sedimentation And Turbidity Associated With Dredging, Richard E. Dodge, J. Rimas Vaisnys

Marine & Environmental Sciences Faculty Articles

Analysis of coral growth patterns and populations in Bermuda reveals that living coral abundance on the reefs of Castle Harbor, a location where extensive dredging occurred during 1941- 1943, is much reduced in comparison to external North-South reefs. Dead corals, sampled in the harbor, have skeletal patterns of growth which are similar and which show a marked decline in growth for several years prior to death. For the brain coral genus Diploria, both D. strigosa and D. labyrinthiformis are fairly evenly represented on contemporary North-South reefs and in the assemblages of dead corals from Castle Harbor, while D. labyrinthiformis, …

Cereal Foliage Disease Survey, T N. Khan, A. G. P. Brown

Experimental Summaries - Plant Research

Cereal Foliage Disease Survey A dry season reduced disease to insignificant levels (as measured by this survey) in all areas except the south west. Late rains may have produced some damage to wheat by S. nodorum however but this was probably confined to southern areas. In barley net blotch which has been declining re appeared a major disease in 1977 excepting high rainfall areas, where scald continued to be severe. The level of scald infection was considerably lower which may be associated with relatively higher temperatures and low rainfall. Variety Clipper continued to show high degree of tolerance to net …

Effects Of Stream Channel Improvements On Downstream Floods, Yang H. Huang, Ronald K. Gaynor

KWRRI Research Reports

This report presents a self-calibrating watershed model for predicting the effect of channel improvements on downstream floods. The model is called MOPSET because it is a modified version of OPSET developed several years ago at the University of Kentucky. OPSET is a computerized procedure for determining an optimum set of parameter values by matching synthesized flows with recorded flows. Major modifications include the replacement of the modified Muskingum method of channel routing by a kinematic finite difference method, the division of the watershed into a number of segments, and the inclusion of a storage routing procedure to take care of …

Modes Of Gulf Stream Intrusion Into The South Atlantic Bight Shelf Waters, Larry P. Atkinson

CCPO Publications

Consideration is given to the intrusion of Gulf Stream waters into the shelf waters of the South Atlantic Bight. It is observed that three modes of intrusion may occur, depending on particular ambient shelf water density. They are override, interleave, and bottom intrusion. It is noted that: (1) except in January, when the shelf water densities are relatively higher, 20°C Gulf Stream water can form a bottom intrusion anywhere along the coast, (2) Gulf Stream waters of 24°C can only form bottom intrusions from April to November, and (3) the rest of the year, 24°C waters interleave or override.

Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks

All Master's Theses

The purpose of this study was to determine if deforestation by a recent outbreak of Douglas-fir tussock moth and logging of such deforested timber has had any effect on stream water quality. To determine this, seven different watersheds of three types were examined. The three types were: undamaged watersheds as controls, watersheds with deforestation and watersheds with deforestation where the timber was subsequently logged. Twenty-four variables were used to determine water quality. Included were seven biological and seventeen chemical variables.

In general, the results indicate only seasonal fluctuations and differences between watersheds due to inherent properties of individual watersheds. Increased …
