An Assessment Of Alternative Feed Ingredients In Practical Diets For Florida Pompano (Trachinotus Carolinus) Held In Low Salinity Recirculating Systems, Terhea Nichole Williams

Electronic Theses and Dissertations

The identification of alternative protein sources for partial or whole replacement of fishmeal (FM) is a priority in the development of suitable, low cost feed formulations for the Florida pompano (Trachinotus carolinus). To evaluate alternative feed ingredients for the potential replacement of FM in diets fed to juvenile pompano, a series of four experiments were conducted. The objectives of Experiments 1 and 2 were to determine the apparent digestibility of crude protein (ADCP), energy (ADE), and apparent amino acid availability (AAAA) of three plant based ingredients (soybean meal (SBM), soy protein isolate (SPI), corn gluten meal (CGM)) and three by-product …

Modeling The Electrodynamics Of The Low-Latitude Ionosphere, Christian Stephen Wohlwend

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The electrodynamics of the Earth's low-latitude ionosphere is dependent on the ionospheric conductivity and the thermospheric neutral density, temperature, and winds present. This two-part study focused on the gravity wave seeding mechanism of equatorial plasma depletions in the ionosphere and the associated equatorial spread F, as well as the differences between a two-dimensional flux tube integrated electrodynamics model and a three-dimensional model for the same time period. The gravity wave seeding study was based on a parameterization of a gravity wave perturbation using a background empirical thermosphere and a physics-based ionosphere for the case of 12 UT on 26 September …

Surface Water Interaction With The Flood Plain In The Lower Virgin River, Clark County, Nevada, Jeffrie L. Pompeo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Development of existing surface water rights on the Virgin River would decrease Southern Nevada's dependency on the Colorado River. Three monitoring sites were established to examine the relationship between Virgin River surface water flows and the floodplain aquifer. Automated water level measuring devices were installed in piezometers and wells to continuously track water levels and flow direction. Pump tests were conducted to establish the hydraulic parameters of the floodplain aquifer. Water chemistry data was analyzed to help determine the correlation between the floodplain aquifer and Virgin River water. Precipitation, recharge, streamflow and ET estimates were used to discuss water budgets. …

Collaborative Research: The Effect Of Iron-Complexing Ligands On Iron Availability To Phytoplankton In Hnlc Waters Of The Subarctic Pacific Ocean, Mark L. Wells, Mary Jane Perry, Charles Trick

University of Maine Office of Research Administration: Grant Reports

Scientists from the University of Maine and San Francisco State University propose to do deck-board incubation experiments in high nutrient, low chlorophyll (HNLC) waters of the eastern (Ocean Station PAPA) and the western (Ocean Station KNOT) Subarctic Pacific Ocean to determine how Fe supply affects phytoplankton species composition. Specifically, this team of scientists plans to address the following specific objectives: (1) assess how the relative availability of Fe bound to weaker and stronger classes of ligands differs among different phytoplankton groups (cyanobacteria, diatoms, dinoflagellates, prymnesiophytes) and how these differences influence the evolution of the phytoplankton community after Fe enrichment in …

Observations Of Clustering Inside Oceanic Bubble Clouds And The Effect On Short-Range Acoustic Propagation, Thomas C. Weber

Center for Coastal and Ocean Mapping

It has recently been shown [Weber, T. C. et al. (Year: 2007). “Acoustic propagation through clustered bubble clouds,” IEEE J. Ocean. Eng.32, 513–523] that gas bubble clustering plays a role in determining the acoustic field characteristics of bubbly fluids. In particular, it has been shown that clustering changes the bubble-induced attenuation as well as the ping-to-ping variability in the acoustic field. The degree to which bubble clustering exists in nature, however, is unknown. This paper describes a method for quantifying bubble clustering using a high frequency (400kHz) multibeam sonar, and reports on observations of near-surface bubbleclustering during a storm ( …

Seasonal Changes In A Eutrophic Lake, Wilgreen Lake, Madison County, Kentucky, Richard D. Stockwell, Walter S. Borowski

EKU Faculty and Staff Scholarship

WilgreenLake (Madison County, Kentucky) covers ~169 acres, formed in 1966 by damming Taylor Fork. The Wilgreen watershed drains residential developments, modified woodlands, cattle pasture, and some industrial/urban areas in the city of Richmond. The lake is deemed “nutrient impaired” by the EPA.

Our main objective is to document the seasonal changes in key lake parameters from summer stratification through fall overturn over 4 months of sampling, August through November, 2008. We collect temperature, oxygen, pH, and conductivity data from 19 stations at depth intervals of 1 meter using an YSI multi-probe. Concurrent with collecting these framework data, we take water …

Restoration Of Dredged Canals In Wetlands: A Comparison Of Methods, Joseph Baustian, R. Eugene Turner, Nancy F. Walters, David P. Muth

Faculty Publications

A comparison of two methods for restoring dredged canals to wetlands was examined at the Jean Lafitte National Historical Park and Preserve’s Barataria Preserve Unit near New Orleans, LA. Both northern and southern canals had the remnant dredged spoil material returned to the canal, but the southern canal had additional sediment pumped in from a nearby lake. The water depth in the southern canal shallowed significantly from 1.2 to 0.4 m following backfilling and sediment addition, while the depth of the northern canal (which received no additional sediment) remained unchanged following backfilling. Neither site had complete soil restoration, but the …

Singh, Andrew Weinheimer

Earth Sciences

We use an ensemble of aircraft, satellite, sonde, and surface observations for April-May 2006 (NASA/INTEX-B aircraft campaign) to better understand the mechanisms for transpacific ozone pollution and its implications for North American air quality. The observations are interpreted with a global 3-D chemical transport model (GEOS-Chem). OMI NO2 satellite observations constrain Asian anthropogenic NOx emissions and indicate a factor of 2 increase from 2000 to 2006 in China. Satellite observations of CO from AIRS and TES indicate two major events of Asian transpacific pollution during INTEX-B. Correlation between TES CO and ozone observations shows evidence for transpacific ozone pollution. The …

Consequences Of More Extreme Precipitation Regimes For Terrestrial Ecosystems, S. D. Smith, C. Beier, Aimee T. Classen, Melinda D. Smith, Jana L. Heisler, S. W. Leavitt, Alan K. Knapp, D. Briske, Y. Luo, M. Reichstein, J. E. Bell, Philip A. Fay, R. Sherry, Benjamin Smith

Life Sciences Faculty Research

Amplification of the hydrological cycle as a consequence of global warming is forecast to lead to more extreme intra-annual precipitation regimes characterized by larger rainfall events and longer intervals between events. We present a conceptual framework, based on past investigations and ecological theory, for predicting the consequences of this underappreciated aspect of climate change. We consider a broad range of terrestrial ecosystems that vary in their overall water balance. More extreme rainfall regimes are expected to increase the duration and severity of soil water stress in mesic ecosystems as intervals between rainfall events increase. In contrast, xeric ecosystems may exhibit …

Occohannock Creek Shoreline Erosion Assessment And Living Shoreline Options Report, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine Wilcox, Shoreline Studies Program, Marcia Berman, Sharon Killeen, Tami Rudnicky, Center For Coastal Resources Management

Reports

This study provides information to Occohannock Creek property owners to help them assess their shoreline stability and their options if erosion is a problem. In the past, shoreline erosion control options were typically limited to rip-rap, groins, or bulkheads. These hard structures often destroyed marsh and other habitat and may not have provided the protection desired. Other methods of erosion control now exist that have been used in a variety of conditions and evaluated for their durability and performance. The alternative techniques incorporate vegetation and are referred to as Living Shoreline designs. Conditions on Occohannock Creek make it a very …

Spatial Analyses And Repletion Of Gargathy Coastal Lagoon, Loreto Herraiz Gomez

OES Theses and Dissertations

Coastal lagoons and bays vary in shape and size in response to antecedent topography, geologic processes and sea level rise. Variations in shape and environmental conditions of coastal basins are believed to influence the distribution of benthic sub-environments and the exchange of water with the ocean and other adjacent coastal systems. Gargathy Inlet and its coastal lagoon vary spatially from the inlet, where the greatest depths are observed, to the mainland, dominated by shallow intertidal areas, colonized by marsh. Hypsographic and hydro-hypsographic analyses of Gargathy's coastal lagoon were the primary techniques applied to understand the relative distribution of the benthic …
