Alkaline Phosphatase Activity And Phosphorus Limitation In Marine Macroalgae From The Florida Keys And The Bahamas, Christine M. Urnezis Jan 1995

Alkaline Phosphatase Activity And Phosphorus Limitation In Marine Macroalgae From The Florida Keys And The Bahamas, Christine M. Urnezis

HCNSO Student Theses and Dissertations

Anthropogenic nutrient enrichment and coastal eutrophication are a primary threat to the biological integrity of coral reef ecosystems. Macroalgal blooms are one symptom of eutrophication and provide useful 'bioindicators' of the nutrient dynamics associated with the eutrophication process. This study used marine macroalgae to monitor physiological processes associated with eutrophication by comparing the degree of phosphorus (P) limitation in reef and nearshore environments of the highly developed Florida Keys with the relatively pristine Bahamas by measuring enzymatic alkaline phosphatase activity (APA), tissue composition, and water column nutrient concentrations [total nitrogen (TN) and total phosphorus (TP)]. Experimental nutrient enrichment studies were …

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

A building thermal model was used to compute hourly values of temperature humidity index (THI) for a broiler house with and without an evaporative misting system. Hourly summer time weather data for 238 U.S.A. locations covering 30 years were used to develop extreme occurrences of THI. Results were incorporated into a Geographical Information System (GIS) database to create isolines of THI and percentage of hours exceeding a heat stress threshold. Regional variations in misting as a suitable cooling technique are presented in terms of hours reduction in annual heat stress. The technique may be used for assisting in management decisions …

THE ANTARCTIC marine ecosystem-the assemblage of plants, animals, ocean, sea ice, and island components south of the Antarctic Convergence is among the largest readily defined ecosystems on Earth (36 X 106 km2 ) (Hedgpeth, 1977; Petit et al., 1991). This ecosystem is composed of an interconnected system of functionally distinct hydrographic and biogeochemical subdivisions (Treguer and Jacques, 1992) and includes open ocean, frontal regions, shelf-slope waters, sea ice, and marginal ice zones. Oceanic, atmospheric, and biogeochemical processes within this system are thought to be globally significant, have been infrequently studied, and are poorly understood relative to more accessible marine ecosystems …


Recreational And Angler Survey Of The Buffalo National River, Arkansas, James E. Johnson Jan 1995

Recreational And Angler Survey Of The Buffalo National River, Arkansas, James E. Johnson

Journal of the Arkansas Academy of Science

The Buffalo River in northern Arkansas was surveyed for recreator and angler use in 1991 and 1992. The river was divided into three reaches and numbers of boats, recreators, anglers, and catches were compiled by creel clerks at nine selected take-out points. Outfitter rental receipts were used to estimate rental boats, and the proportion of rental to private boats creeled was used to correct for private boats not counted on the rental receipts. A total of 1,656 boats containing 3,071 recreators was contracted by the creel clerks during 1991 and 1992; 9.2% of the recreators were anglers. Expansion of the …

Current Meter Observations In The Old Bahama Channel, L. P. Atkinson, T. Berger, P. Hamilton, E. Waddell, K. Leaman, T. N. Lee

CCPO Publications

Current meter observations were made at 50, 250, and 435 m in 495 m of water at the center of the Old Bahama Channel between November 1990 and November 1991. The mean speed at those depths was 2.6, 50, and 26 cm s-1 toward the Straits of Florida. A maximum speed of 193 cm s-1 was found at the 250-m level. There was evidence of a speed maximum between 50 and 250 m. Large internal diurnal tidal currents were observed that produced high shears in the water column under some conditions. Transport calculated from the single mooring using …

CCPO Publications

Distributions of physical, biological, and chemical parameters in Florida Keys coastal waters seaward of the reef track were surveyed on September 9 to 13, 1993, as part of a coordinated multidisciplinary study of surface transport processes. A band of low-salinity water was observed along the shoreward side of the Florida Current over the downstream extent of the survey from Miami to Key West. Biological and chemical indicators within the band, together with its large volume, satellite imagery, and a surface drifter trajectory suggested the recent Mississippi River flood as the source.


The Effects Of Nutrient Loading On Plant And Algae Population: A Comparison Study Of East Gemini Lake And Lower Stumpf Lake, Nick Leonard Jan 1995

The Effects Of Nutrient Loading On Plant And Algae Population: A Comparison Study Of East Gemini Lake And Lower Stumpf Lake, Nick Leonard

Honors Theses, 1963-2015

Eutrophication of lakes has become an increasing problem for many bodies of water. By analyzing the nutrients available and the phytoplankton and macrophyte populations, evaluation and differentiation of East Gemini Lake and Stumpf Lake were made concerning their trophic state. This determination allowed for the further understanding of the effect the trophic state has on the flora of an aquatic system. It was determined that East Gemini Lake was eutrophic based on its available nutrients and phytoplankton populations. In contrast, Stumpf Lake was determined to be mesotrophic having lower available nutrients and less phytoplankton population density with fewer major phytoplnakton …

Finally, it is hoped that this research will …


The National Marine Sanctuary Designation Process And Its Impact On Naval Operations, Gregory E. Bolan Jan 1995

The National Marine Sanctuary Designation Process And Its Impact On Naval Operations, Gregory E. Bolan

Marine Affairs Theses and Major Papers

This paper addresses the basis of potential and real conflicts derived by the National Environmental Protection Act (NEPA) process, as identified within and between NOAA and the United States Navy. This conflict is often exacerbated due to either a lack of communication, coordination, or both. A recent proliferation of proposed and designated marine sanctuaries in traditional Naval operating areas has complicated or hindered Naval operations (or will) to a degree where EIS derived restrictions negatively impact the Naval operations, based on (1) response readiness, and (2) increased cost of operations. Two specific conflicts are examined in a case study approach …


An Assessment Of The Safety Of Navigation: The Malaysian Perspective In The Straits Of Malacca, Amir Bin Murad Jan 1995

An Assessment Of The Safety Of Navigation: The Malaysian Perspective In The Straits Of Malacca, Amir Bin Murad

Marine Affairs Theses and Major Papers

The traffic movements in the Straits of Malacca (SOM) have been ever increasing over the past few years resulting in numerous marine casualties that have caused serious concern to the Government of Malaysia. Current characteristics of navigation in the SOM present a potential major catastrophe. The first hypothesis is that there is a positive relationship between traffic movement and the number of marine casualties. Thus, an increase in traffic movement will result in an increased risk of marine casualties. The second hypothesis is that the Traffic Separation Scheme (TSS) did not change the overall trend of marine casualties that occurred …


The National Estuary Program's Watershed Protection Approach: An Analysis Of Local Governments, Constituency Organizations And Watershed Residents In Addressing Nonpoint Source Pollution In The Buzzards Bay Project, Paula Renier Jewell Jan 1995

The National Estuary Program's Watershed Protection Approach: An Analysis Of Local Governments, Constituency Organizations And Watershed Residents In Addressing Nonpoint Source Pollution In The Buzzards Bay Project, Paula Renier Jewell

Marine Affairs Theses and Major Papers

Reduction of coastal nonpoint source (NPS) pollution requires an innovative approach. Efforts must comprehensively address the cumulative effects of individual behaviors. Therefore, program objectives must apply to the entire contributing watershed, but emphasize local implementation. Local governments must be empowered to install regulatory and other mechanisms to reduce NPS pollution. Local citizen organizations such as watershed associations, must effectively educate watershed citizens about their ole in NPS pollution. Watershed citizens must change their behaviors which contribute to the problem. However, developing a vibrant constituency around NPS pollution itself remains a serious challenge to mitigation efforts. As a geographically defined, holistic …


The New Certificates Of Financial Responsibility: Environmental Progress Or National Economic Disaster?, Paul R. Younes Jan 1995

The New Certificates Of Financial Responsibility: Environmental Progress Or National Economic Disaster?, Paul R. Younes

Marine Affairs Theses and Major Papers

The Oil Pollution Act of 1990 (OPA 90) is the first comprehensive oil spill legislation passed in the United States. Included in the law were new provisions governing the liability and financial responsibility of both the company responsible for the spill and the insurer. These provisions, while well-intentioned, have created a dangerous situation for both the environment and the economy of the United States. This paper will examine the financial responsibility and liability regime that was in place prior to the passage of OPA 90, and the provisions of OPA 90 that establish new requirements shipowners must meet to qualify …

Ocean Transport Of Containerized Liner Cargo In The United States-Mexico Trade, Carl Joseph Williams Jan 1995

Ocean Transport Of Containerized Liner Cargo In The United States-Mexico Trade, Carl Joseph Williams

Marine Affairs Theses and Major Papers

Commerce between the United States and Mexico will continue to grow due to the incremental benefits of the North American Free Trade Agreement. This growth, however, will be slowed at least temporarily by the recent Mexican Peso crisis. Ocean transportation currently only moves about 8.5 percent of US-Mexico cargo by value even though it is the most efficient mode of transport over longer distances. This study hypothesized that the underutilized ocean transport sector has captured significant high-growth general cargo that is amenable to containerized transport from the air and/or trucking and rail sectors of the US-Mexico trade. Historical and ex …


North American Sea Urchin Fishery Management Strategies: Their Applicability To The Maine Green Sea Urchin Fishery, Kate Sullivan Jan 1995

North American Sea Urchin Fishery Management Strategies: Their Applicability To The Maine Green Sea Urchin Fishery, Kate Sullivan

Marine Affairs Theses and Major Papers

The Maine green sea urchin fishery has experienced dramatic growth since its inception in 1987. Landings have increased from 1.4 million pounds in 1987 to 41.6 million pounds in 1993 (NMFS, Fisheries Statistics). The reproductive gonads, referred to as roe or 'uni' are shipped fresh from Maine to japan, where the uni is a delicacy item fetching high unit prices on the Japanese fish market. The green sea urchin from Maine, Strongylocentrotus droebachiensis, is the third highest priced sea urchin product imported in Japan (Anon., 1989). Country-wide, sea urchin fisheries are one of the fastest growing fishing industries (Phu, …


Liability Issues In The Development Of Electronic Chart Display Information Systems, Daniel R. Martin Jan 1995

Liability Issues In The Development Of Electronic Chart Display Information Systems, Daniel R. Martin

Marine Affairs Theses and Major Papers

The Electronic Chart Display Information System (ECDIS) is a new and evolving aid to navigation. Proponents claim ECDIS will help navigators to synthesize previously disparate information and result in safer navigation. The technology to implement ECDIS already exists; the major hurdle the maritime community faces is the legal uncertainties associated with ECDIS. This paper investigates the potential legal impact ECDIS would have on the government, shipowners, mariners, and manufacturers, and evaluates current international efforts to promote ECDIS. Through a detailed analysis of admiralty and aeronautical case history, it is evident that; 1) generation of electronic nautical charts can post a …


Implementation Of Harbor Management Plans: The Next Generation Of Mooring Management Incorporates Gps And Gis, Tracy E. Lang Jan 1995

Implementation Of Harbor Management Plans: The Next Generation Of Mooring Management Incorporates Gps And Gis, Tracy E. Lang

Marine Affairs Theses and Major Papers

This paper describes the development of a spatial decision-support and management system to be used for improved coastal and harbor management. The design combines two separate systems, one is the use of Global Positioning Systems (GPS), and the other is the use of a Geographic Information (GIS) (ARCVIEW II). This pilot project specifically examined the use of GPS and GIS to identify, map, and monitor individual mooring buoys in one recreational harbor in Narragansett, Rhode Island. GPS was used for collection of positional information and was compared to one traditional marine positioning device, Loran-C, and the variations between each method …


Rapid Rural Appraisal Of Household Adaptations To The Coastal Zone Of Ecuador, Jennifer A. Pereira Jan 1995

Rapid Rural Appraisal Of Household Adaptations To The Coastal Zone Of Ecuador, Jennifer A. Pereira

Marine Affairs Theses and Major Papers

It has become clear to those interested in development that the household is an integral institution linking the individual to the society and the environment. Understanding the functioning of this institution will facilitate improvements in planning, evaluation, and output of development projects. Development projects suffer from a lack of efficient research methods for collecting socioeconomic information regarding the household. It has been proposed that Rapid Rural Appraisal (RRA), a method of field work that is timely, flexible, and places an emphasis on local participation, may be an appropriate method for collecting these types of data. RRA was originally developed for …


Managine For Effectiveness And Efficiency In Oil Spill Response, Peter A. Tebeau Jan 1995

Managine For Effectiveness And Efficiency In Oil Spill Response, Peter A. Tebeau

Marine Affairs Theses and Major Papers

Responding to oil spills, even spills of moderate proportion, requires the commitment of substantial manpower and equipment on the part of the responsible party or the federal government. Throughout the response operation, successful spill management entails choosing the most effective and efficient countermeasures and cleanup techniques to remove or neutralize oil in the environment, minimize overall environmental damages from the spill, and insure that the objectives and expectations of government agencies, responsible parties, and the public are met. As the response progresses, effective and efficient management requires determining when response operations should be terminated. In making this decision, the On-Scene …


The Ocean Research Vessel Act Of 1965: An Inequitable Result Suggests Reevaluation, Philip Alan Sacks Jan 1995

The Ocean Research Vessel Act Of 1965: An Inequitable Result Suggests Reevaluation, Philip Alan Sacks

Marine Affairs Theses and Major Papers

In 1965 Congress passed the ocean Research Vessel Act (ORVA) with the purpose of encouraging the nation's efforts in oceanographic studies. Section 4 of the ORVA states that "scientific personnel on an oceanographic research vessel shall not be considered seamen under the provisions of title 53 of the Revised Statues...". As a result of a literal interpretation of this wording, the Courts have ruled that scientific personnel are excluded from the beneficial remedies afforded all other seamen under the Jones Act. Some courts have also denied an injured scientist "seaman status" under the general maritime law. This paper argues that …


The Rhode Island Marine Fisheries Council: Stewardship In Need Of Goals And Objectives, Robert Censabella Jan 1995

The Rhode Island Marine Fisheries Council: Stewardship In Need Of Goals And Objectives, Robert Censabella

Marine Affairs Theses and Major Papers

In the State of Rhode Island, marine fisheries are managed through the Marine Fisheries Council, a citizen-based regulatory body of nine members from either the commercial or recreational fishing industries or experienced with the conservation and management of fisheries resources. To ostensibly help this group make informed decisions, biological data and scientific advice are provided by the State Division of Fish and Wildlife. This thesis examines the decision-making process of this Council. More specifically, it provides a case study of how this body has attempted to manage the State's winter flounder stocks-an economically-valuable species which confines its life cycle mostly …


The Use Of Targeting In Port State Control, Mary E. Landry Jan 1995

The Use Of Targeting In Port State Control, Mary E. Landry

Marine Affairs Theses and Major Papers

This study will examine two separate, but related matters; (1) expansion of port State control through new treaties and international practice, and (2) the port State's use of targeting to focus its attention on substandard performance. It will also outline and clarify the practice of targeting which has been employed under several regional port State control agreements throughout the world. This study will examine targeting as an economic sanction; in essence, a coercive measure using financial disincentives to discourage substandard performance in the maritime community. Targeting was designed or developed as an economic sanction. Rather, it was marketed as a …


Assessing The Impact Of Amendment 2 To The Summer Flounder Fishery Management Plan: Implications Of State-By-State Quotas For Vessel Operators, Karen Ellis Greene Jan 1995

Assessing The Impact Of Amendment 2 To The Summer Flounder Fishery Management Plan: Implications Of State-By-State Quotas For Vessel Operators, Karen Ellis Greene

Marine Affairs Theses and Major Papers

The state-by-state quota regulation contained in Amendment 2 to the Summer Flounder Fishery Management Plan became effective on January 1, 1993. The research sought to determine the implications that the state-by-state quotas have imposed on federal summer flounder permit holders. commercial fishermen were believed to have landed their summer flounder out-of-state to take advantage of more favorable possession limits in other states, and to have accrued higher costs as a result of their decisions to land out-of-state. A survey was administered to commercial fishermen in Massachusetts, Rhode Island, and North Carolina, to ascertain behavioral changes, as a result of state-by-state …


Environmental Messages In Boating Magazines: A Content Analysis Of Recreational Power Boating Articles, Robert S. Holtzman Jan 1995

Environmental Messages In Boating Magazines: A Content Analysis Of Recreational Power Boating Articles, Robert S. Holtzman

Marine Affairs Theses and Major Papers

This paper presents the results of a study analyzing the editorial content of consumer power boating magazines for messages of environmental responsibility. It presents evidence of a cause and effect relationship between recreational power boating and damage to the marine environment, and cites arguments that power boating in its currently popular form, involving high speeds and heavy fuel consumption, is inherently "unfriendly" to the environment. The paper describes a "chain of influence" through which boat manufacturers, in their role as advertisers, influence the editorial content of consumer boating magazines through the tactics of marketing public relations. A hypothesis is developed …


Atlantic Bluefin Tuna Management, Jeffrey C. Fisher Jan 1995

Atlantic Bluefin Tuna Management, Jeffrey C. Fisher

Marine Affairs Theses and Major Papers

The International Commission for the Conservation of Atlantic Tunas (ICCAT) and federal management under the U.S. National marine Fisheries Service (NMFS) has certainly been contentious. Atlantic bluefin tuna have been managed at the international level by ICCAT for the past 25 years. NMFS is the organization responsible for implementing ICCAT recommended conservation and management measures in the United States. In an attempt to halt an apparent decline in the abundance of bluefin tuna in the western Atlantic, ICCAT has recommended strict management measures including catch quotas, minimum sizes, "no-sale" provisions, and spawning area protection since 1981. ICCAT had recommended in …


International Management Of The Western Atlantic Bluefin Tuna Fishery: Is There A Need For A Cites Listing?, Jennifer Elling-Dodge Jan 1995

International Management Of The Western Atlantic Bluefin Tuna Fishery: Is There A Need For A Cites Listing?, Jennifer Elling-Dodge

Marine Affairs Theses and Major Papers

In the last two decades, the Atlantic bluefin tuna has been increasingly targeted by fishermen throughout the world, primarily for sale in Japan. Commercial fishermen, attempting to survive in a world of declining commercial catches, increased controls on fishing effort, and increasing competition, view the U.S. $50.00 or more per kilogram that might be obtained from bluefin as a financial bonanza. yet, the population of breeding adult bluefin in the western Atlantic (the focus of bluefin fishing, since the largest bluefin consistently occur there) has declined by an estimated 77% to 90% since the 1970's. In addition, the eastern Atlantic …

Description And Vorticity Analysis Of 50-Day Oscillations In The Western Tropical Region Of The Cme Model, Julie L. Mcclean, John M. Klinck

CCPO Publications

The WOCE Community Modeling Effort (CME) general circulation model of the North Atlantic was used to investigate the behavior, nature, and dynamics of 50-day oscillations seen in the meridional component of velocity between 5 degrees and 11 degrees N, 35 degrees and 55 degrees W. Oscillations of the meridional component of velocity, with a period of about 50 days, appear as the seasonal meander pattern of the North Equatorial Countercurrent starts to break down in December. They appear first near 35 degrees W and are advected westward. They have a westward phase velocity of about 0.1 m s(-1), wavelength of …
