The Effects Of Property Rights On Ocean Resources: Two Possible Solutions To The Tragedy Of The Commons, Nathan David Miller May 2012

The Effects Of Property Rights On Ocean Resources: Two Possible Solutions To The Tragedy Of The Commons, Nathan David Miller

Honors Program Theses

Property rights affect how people use resources. Enforcement regimes are able to set clear laws with well-defined property rights. Governments set laws for conservation and economic success. Ocean resources suffer from overuse. Industry and the environment both benefit from regulations that promote ocean conservation. This paper will analyze how the current state of ocean property rights leads to the depletion of ocean resources. Though there are many possible solutions to overfishing, I will analyze two potential solutions to overexploitation in the commercial fishing industry: marine protected areas (MP As) and individual transferable quotas (ITQs ). A synthesis of previous research …


The Impacts Of Population Density, And State & National Litter Prevention Programs On Marine Debris, Melissa Rose Brogle Mar 2012

The Impacts Of Population Density, And State & National Litter Prevention Programs On Marine Debris, Melissa Rose Brogle

USF Tampa Graduate Theses and Dissertations

Marine debris is improperly disposed of solid waste, also called litter, which is deposited in the marine environment (NOAA, 2010). Litter prevention techniques such as fines, cleanups, incentives, and others, can help to decrease litter, and ultimately decrease marine debris. This research analyzed 2000 and 2010 International Coastal Cleanup (ICC) data obtained from The Ocean Conservancy to ascertain whether certain litter prevention techniques did reduce amounts and types of marine debris found in coastal areas. The litter prevention techniques analyzed included state bottle bills, voluntary monofilament fishing line recycling programs, and the Keep America Beautiful (KAB) cigarette butt litter prevention …

Understanding feedbacks of ecosystem carbon sequestration to climate change is an urgent step in developing future ecosystem models. Using 187 site-years of flux data observed at 24 sites covering three plant functional types (i.e. evergreen forests (EF), deciduous forests (DF) and non-forest ecosystems (NF) (e.g., crop, grassland, wetland)) in North America, we present an analysis of both interannual and spatial relationships between annual net ecosystem production (NEP) and phenological indicators, including the flux-based carbon uptake period (CUP) and its transitions, degree-day-derived growing season length (GSL), and spring and autumn temperatures. Diverse responses were acquired between annul NEP and these indicators …


Responses To Chemical Exposure By Foraminifera: Distinguishing Dormancy From Mortality, Benjamin James Ross Jan 2012

Responses To Chemical Exposure By Foraminifera: Distinguishing Dormancy From Mortality, Benjamin James Ross

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout in 2010 released an estimated 4.9 million barrels of crude oil into the Gulf of Mexico in the 83 days between the initial explosion and the capping of the well. Response included extensive use of Corexit© oil dispersant. Although South Florida was spared exposure by currents, this event highlights the need for effective bioassay organisms for coral reefs. Amphistegina spp. are benthic foraminifers that host diatom symbionts in a relationship similar to that of coral and their zooxanthellae. Amphistegina spp. occur abundantly in reef communities nearly worldwide, are easily collected and maintained in culture, and are …

The Journal of Purdue Undergraduate Research

Wind turbines are becoming increasingly widespread in the United States as the world looks for cleaner sources of energy. Scientists, policymakers, and citizens have strong opinions regarding the positive and negative effects of wind energy projects, and there is a great deal of misinformation about wind energy circulating on the Web and other media sources. The purpose of this study is to gain a better understanding of how the rotation of hundreds of turbines can influence local weather conditions within a wind farm and in the surrounding areas. This experiment measures temperature, atmospheric pressure, wind speed, wind direction, relative humidity, …


Identifying Changes In Climatic Trends And The Fingerprints Of Landuse And Landcover Changes In The High Plains Of The Usa, Denis Mutiibwa Jul 2011

Identifying Changes In Climatic Trends And The Fingerprints Of Landuse And Landcover Changes In The High Plains Of The Usa, Denis Mutiibwa

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Human activities such as conversion of natural ecosystem to croplands and urban-centers, deforestation and afforestation impact biophysical properties of land surface such as albedo, energy balance, and surface roughness. Alterations in these properties affect the heat and moisture exchanges between the land surface and atmospheric boundary layer. The objectives of this research were; (i) to quantitatively identify the High plains’ regional climate change in temperatures over the period 1895 to 2006, (ii) detect the signatures of anthropogenic forcing of LULC changes on the regional climate change of the High Plains, and (iii) examine the trends in evolving regional latent heat …


Spatial Patterns Of Drought Triggers And Indicators, Joseph P. Robine May 2011

Spatial Patterns Of Drought Triggers And Indicators, Joseph P. Robine

Department of Environmental Studies: Undergraduate Student Theses

Drought is a reoccurring phenomenon with widespread economic, social, and environmental impacts. Unlike other disasters, a drought cannot be easily detected. In addition, droughts are widespread and develop slowly over time making it difficult to detect its onset and monitor its severity and impacts. To assist in monitoring the severity and spatial extent of droughts, drought managers frequently use indicators and triggers. Drought indicators are meteorological or hydrological variables or indices that quantify or describe the level of drought severity. A drought trigger is a value of an indicator that initiates management and response actions. Despite the clear importance of …


Trends Of Wind And Wind Power Over The Coterminous United States, Eric M. Holt Mar 2011

Trends Of Wind And Wind Power Over The Coterminous United States, Eric M. Holt

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The trends of wind and wind power at a typical wind turbine hub height (80 m) are analyzed using the North American Regional Reanalysis (NARR) dataset for 1979-2009. Based upon the wind speeds at NARR’s vertical layers right above and below the 80 m level, the wind speeds at 80 m are estimated using two methods assuming the wind profile respectively as linear and power-law distribution with respect to the altitude in the lower boundary layer. Furthermore, we calculate the following variables at 80 m that are needed for the estimation and interpretation of wind power: the air density, zonal …

State Of The Climate In 2010, Jessica Blunden, Derek S. Arndt, Molly O. Baringer

United States Department of Commerce: Staff Publications

Several large-scale climate patterns influenced climate conditions and weather patterns across the globe during 2010. The transition from a warm El Niño phase at the beginning of the year to a cool La Niña phase by July contributed to many notable events, ranging from record wetness across much of Australia to historically low Eastern Pacific basin and near-record high North Atlantic basin hurricane activity. The remaining five main hurricane basins experienced below- to well-below-normal tropical cyclone activity. The negative phase of the Arctic Oscillation was a major driver of Northern Hemisphere temperature patterns during 2009/10 winter and again in late …
