Fortnightly Variability At The Transition Between Two Sub-Estuaries, Mayra Lorena Riveron Enzastiga

OES Theses and Dissertations

Profiles of current velocity from an Acoustic Doppler Current Profiler (ADCP) and of water salinity, temperature and density from a Conductivity-Temperature-Depth (CTD) recorder, were combined with surface salinity, temperature and density from a Conductivity-Temperature (CT) recorder to elucidate the fortnightly variability at the Lafayette River entrance. The Lafayette River connects at its mouth with the Elizabeth River, which is a tributary to the James River in the Chesapeake Bay. Data were collected in four experiments during consecutive spring and neap tides in the autumn of 2000, and in the spring of 2001. Each experiment was carried out for -25 hours …

Evaluation Of Satellite-Derived Objective Potential Index For Oceanic Cloud System During The Mei-Yu Period, Chung-Chih Liu, Gin-Rong Liu, Chun-Chieh Chao, Da-Gang Pan, Ji-En Li

Journal of Marine Science and Technology–Taiwan

Many mesoscale convective systems (MCSs) accompanied by heavy rainfall are frequently observed over the Taiwan Strait along the Mei-Yu front. An objective potential index of air-sea interaction was proposed by employing satellite data for pointing out areas where oceanic convective clouds may occur and develop into MCSs [11]. The aim of present research is to evaluate that index through the data of 2001 and 2002. The results show that a greater objective potential index is correlated with a larger probability of colder infrared brightness temperature. In addition, the analysis of serial correlation for these two discrete parameters (objective potential index …

Morphologic Features Of Conduits And Aquifer Response In The Unconfined Floridan Aquifer System, West Central Florida, Lee J. Florea, H L. Vacher

Earth, Environmental, and Atmospheric Sciences Faculty Publications

Conduits within the unconfined Floridan Aquifer of west-central Florida include both horizontal and vertical components. In this paper, we investigate each and propose theories based upon cave survey data and a collection of over 300 Florida cave maps. First, we find that vertical portions of conduits visually correlate to fractures, and these fractures tend to be the dominant control of conduit directionality. Length-weighted rose diagrams of passage directions reveal a NW-SE and NE-SW pattern of conduit directions statistically similar to results found in remote sensing studies of photolinears. Secondly we note that horizontal elements of conduits occur at consistent horizons …

Will Lowering Estuarine Salinity Increase Gulf Of Mexico Oyster Landings?, R. Eugene Turner

Faculty Publications

Previous studies provide conflicting opinions on whether lower than average salinities in Gulf of Mexico (GOM) estuaries are likely to increase or decrease oyster harvests (Crassostrea virginica), which represented 69% and 54% of the United States oyster landings by weight, and dockside value, respectively, in 2003. The present study examined a 54-yr record (1950–2003) of oyster harvests and river discharge in five major estuaries in GOM states (Florida, Alabama, Mississippi, Louisiana, and Texas). Oyster landings were inversely related to freshwater inflow. Peaks in landings, 21 of 23 in West Florida, Alabama, Mississippi, and Texas combined, were coincidental with …

In Situ Evidence For Renitrification In The Arctic Lower Stratosphere During The Polar Aura Validation Experiment (Pave), Jack E. Dibb, Eric Scheuer, Melody A. Avery, G W. Sachse

Earth Sciences

In-situ measurements of nitric acid (HNO₃), ozone (O₃), and nitrous oxide (N₂O) were made from the NASA DC-8 during the Polar Aura Validation Experiment in January/February 2005. In the lower stratosphere (9–12.5 km, potential temperature 300–350 K) characteristic compact relationships were observed between all three gases. The ratio HNO₃/O₃ averaged 3.5 (±0.7) ppt/ppb. Samples with enhanced HNO₃/O₃ (>4.0) were most abundant under the edge of the Arctic Polar vortex in airmasses with enhanced mixing ratios of both gases (>400 ppb O₃ and >2000 ppt HNO …

Human Development And Resources Use In The Coastal Zone: Influences On Human Health, Robert E. Bowen, Anamarija Frankic, Mary E. Davis

Environmental, Earth, and Ocean Sciences Faculty Publication Series

Coastal watersheds and nearshore marine areas are the most valuable and dynamic places on Earth. Human population growth is great in these regions, which are home to some of the most sensitive habitats in the world. Coastal areas provide more than half of the overall service value derived from the global environment (Costanza et al., 1997). Natural (e.g., hurricanes and tsunamis) and human pressures on this environment require it to constantly adjust. More than any other area, the global coast has defined the progress of human culture and continues to be a singular influence in how humans connect to the …

Project Title: Sustainable Adaptations To Drought And Climate Variability In Agricultural Production Systems Across Nebraska, Cody L. Knutson, Michael J. Hayes, Robert K. Hitchcock, Jeffrey Peake, Martin Kleinschmit

National Drought Mitigation Center: Faculty Publications

Drought is a normal part of Nebraska’s climate. It is also the leading cause of monetary disaster loss in the United States. FEMA (1995) has estimated that U.S. drought losses average $6-8 billion dollars per year. A majority of these losses are incurred in the agricultural sector. Nebraska’s losses alone topped $1.2 billion in 2002 (AP 2003).
To enhance viable operations in this variable climate, many Nebraska farmers and ranchers have begun making the transition to agricultural practices that fall into the realm of sustainable agriculture. Sustainability has been increasingly stressed as essential for creating more resilient systems and reducing …

The Influence Of North Pacific Atmospheric Blocking On Colorado Lee Cyclogenesis, Diana S. Dickey

All-Inclusive List of Electronic Theses and Dissertations

North Pacific atmospheric blocking is an upper tropospheric phenomenon that occurs modally in the northwestern quadrant of the North American cyclogenetic region primarily during the winter season. In this study, Colorado lee cyclones, which develop to the east of the Rocky Mountains, are investigated to see if differing strengths of North Pacific atmospheric blocking influences cyclone frequency, intensity and tracks during the study period 1965-1995. Three blocking categories, strong blocking, anti-blocking and weak-index blocking were created based on indices provided by previously published research. Additionally, an analysis of upper tropospheric circulation during strong blocking and anti-blocking winter seasons was made …

Biogeochemistry Of Arsenic And Antimony In The North Pacific Ocean, Gregory A. Cutter, Lynda S. Cutter

OES Faculty Publications

The biogeochemical cycles of the metalloid elements arsenic and antimony were examined along a 15,000 km surface water transect and at 9 vertical profile stations in the western North Pacific Ocean as part of the 2002 IOC Contaminant Baseline Survey. Results show that the speciation of dissolved arsenic (As III, As V, and methylated As) was subtly controlled by the arsenate (AsV)/phosphate ratio. An additional fraction of presumed organic arsenic previously reported in coastal waters was also present (~15% of the total As) in oceanic surface waters. Dissolved inorganic antimony displayed mildly scavenged behavior that was confirmed by correlations with …

Substituting Otoliths For Chemical Analyses: Does Sagitta = Lapillus?, Nathan G. Smith, Cynthia M. Jones

OES Faculty Publications

Chemical analysis of fish otoliths has become an important technique in fisheries science with widespread applications. Most research up to this point has focused predominantly on sagittal otoliths, but the underlying assumptions may also apply to lapilli. The goal of this study was to determine whether lapilli and sagittae have the same otolith chemistry and whether one can be substituted for the other for solution-based chemical analysis in wild-captured fish. We compared the stable isotope chemistry (δ13C and δ18O) of paired sagittae and lapilli of juvenile spotted seatrout Cynoscion nebulosus collected from Chesapeake Bay seagrass beds in 2002. …

How Serious Is The Global Warming Threat?, Roy W. Spencer

Center for Applied Economics

Global warming is the quintessential environmental scare. While the local effects of litter, chemical contamination, and aerosol pollution had dominated our environmental concerns in the 1970’s and 1980’s, we are now faced with a threat that is global in extent and predicted to be long-lasting1. The culprit is humanity’s use of fossil fuels, which release carbon dioxide into the atmosphere when burned. Since carbon dioxide is a ‘greenhouse gas’, it affects the radiative energy budget of the Earth. While carbon dioxide is a relatively minor atmospheric constituent, with a concentration now approaching 400 parts per million (pre-industrial levels were about …

Sea Urchin Predation In Misali Island Marine Park, Nicole Esclamado

Independent Study Project (ISP) Collection

The populations of sea urchins and their main predators, triggerfish (Balistidae), wrasses (Labridae) and emperors (Lethrinidae), were studied in the extractive and non-extractive zones of the Misali Island Marine Conservation Area in order to (1) evaluate the applicability of a sea urchin-sea urchin predator model developed in Kenya’s fringing reefs, (2) gain baseline data on Misali’s coral reef, and (3) evaluate the recovery status of the protected zone. This study revealed the predictive power of the sea urchin-sea urchin predator model for the reef ecosystem of Misali Island. As expected, a decline in sea urchin predators as a gross trophic …

The Influence Of High Temperature And Two Hurricanes On The Success Of Late Season Loggerhead Nests In Broward County, Florida, In 2005, Stefanie Ouellette, Curtis M. Burney

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

The success of loggerhead nests, defined as the percentage of the eggs per nest resulting in live released hatchlings, declined to unusually low levels during the latter part of the 2005 season. The mean successes were 81.1, 61.1, 32.8 and 13.4 percent for nests deposited in May, June, July and August, respectively. Many eggs from the August nests appeared to be unusually dried. There was a significant inverse relationship (P < .0001) between the daily air temperature anomaly on the day of nest deposition and the average daily success rate of loggerhead nests in 2005. The daily temperature anomaly is the deviation of the average air temperature each day from the daily climatological average values. There was also a highly significant inverse relationship between maximum daily air temperature and nest success rate in 2005. These relationships were not found in the previous two years. The actual average temperature during August in 2005 was 29.7°C, compared to 28.9 and 29.2°C in 2004 and 2003, respectively. The 2005 average was statistically different from the other two years (one way ANOVA, P < .001) and also from the climatological average temperature of 28.6°C. Mean daily success rates were less than 50 percent for nests deposited during the 50 days preceding the impact of Hurricane Katrina on August 25. Nests deposited in the first two weeks of August were also impacted by Hurricane Rita. Mean daily success rates were less than 10 percent on 7 days during this period.

Magnetic Coupling Between A “Hot Jupiter” Extrasolar Planet And Its Pre-Main-Sequence Central Star, Brooke E. Alarcon

Master's Theses - Daytona Beach

In order to understand the short-period pile-up of extrasolar planets, the magnetic torque of a pre-main-sequence central star on a single orbiting "hot Jupiter" planet is calculated. The star's magnetic field is modeled as a dipole magnetic field. The time-dependent stellar radius is calculated for four different stellar mass sizes; 2Msum \.5Msum \Msum and 0.5Msurt. The minimum planetary ionization for the giant gas planet to be nearly frozen to the magnetic field lines is calculated. The changing angular momentum of an orbiting body was balanced with the magnetic torque of the central star to provide …
