- Deep-Water Biogenic Sediment off the Coast of Florida.
- Creator
- Zuccarelli, Claudio L., Oleinik, Anton E., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Geosciences
- Abstract/Description
-
Biogenic “oozes” are pelagic sediments that are composed of > 30% carbonate microfossils and are estimated to cover about 50% of the ocean floor, which accounts for about 67% of calcium carbonate in oceanic surface sediments worldwide. These deposits exhibit diverse assemblages of planktonic microfossils and contribute significantly to the overall sediment supply and function of Florida’s deep-water regions. However, the composition and distribution of biogenic sediment deposits along these...
Show moreBiogenic “oozes” are pelagic sediments that are composed of > 30% carbonate microfossils and are estimated to cover about 50% of the ocean floor, which accounts for about 67% of calcium carbonate in oceanic surface sediments worldwide. These deposits exhibit diverse assemblages of planktonic microfossils and contribute significantly to the overall sediment supply and function of Florida’s deep-water regions. However, the composition and distribution of biogenic sediment deposits along these regions remains poorly documented. Seafloor surface sediments have been collected in situ via Johnson- Sea-Link I submersible along four of Florida’s deep-water regions during a joint research cruise between Harbor Branch Oceanographic Institute (HBOI) and Florida Atlantic University (FAU). Sedimentological analyses of the taxonomy, species diversity, and sedimentation dynamics reveal a complex interconnected development system of Florida’s deep-water habitats. Results disclose characteristic microfossil assemblages of planktonic foraminiferal ooze off the South West Florida Shelf, a foraminiferal-pteropod ooze through the Straits of Florida, and pteropod ooze deposits off Florida’s east coast. The distribution of the biogenic ooze deposits is attributed to factors such as oceanographic surface production, surface and bottom currents, off-bank transport, and deep-water sediment drifts. The application of micropaleontology, sedimentology, and oceanography facilitate in characterizing the sediment supply to Florida’s deep-water regions.

Show morePlanners and managers often rely on coarse population distribution data from the census for addressing various social, economic, and environmental problems. In the analysis of physical vulnerabilities to sea-level rise, census units such as blocks or block groups are coarse relative to the required decision-making application. This study explores the benefits offered from integrating image classification and dasymetric mapping at the household level to provide detailed small area population estimates at the scale of residential buildings. In a case study of Boca Raton, FL, a sea-level rise inundation grid based on mapping methods by NOAA is overlaid on the highly detailed population distribution data to identify vulnerable residences and estimate population displacement. The enhanced spatial detail offered through this method has the potential to better guide targeted strategies for future development, mitigation, and adaptation efforts.

As cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas.

Show moreAs cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas. Private greenspace, which is one of the largest land cover types in cities, offers the potential for substantial agricultural production. Because urban food production on private land, such as backyards, requires the willing participation of landowners, resident's feelings about and experience with food growing are important to understand. The demographic groups that were most likely to food garden were those in long-term relationships, higher income brackets, those with college education and residents over 50 years old. Incentives and programs focused on producing more from existing gardens may be most appropriate for people in these demographic groups, while other groups will most require basic food growing information. Study participants highly valued intangible benefits of food gardening (e.g., relaxation, feelings of happiness and satisfaction), often more than the provision of food. Most barriers and problems with backyard food growing, such as a lack of space and the need for gardening information, were similar for those who food garden and those who do not. Results from this study indicate that traditional agricultural incentives and perspectives must be rethought if they are to be applied in urban settings. By creating incentives and initiatives that reflect the needs and challenges faced by urban growers, urban agriculture will become an integrated part of the community, improving food quantity and quality while enriching residents' lives.

Show moreTidal flat refers to the sediment-rich environment along the seashore, which is alternatively exposed or inundated during tidal cycles. It is widely recognized as not only the sentinel of coastal environment change, but also the safeguard for beachfront communities. It is necessary to comprehensively understand the wellness of tidal flat environments, especially for the United States (US), which has the eighth longest coastline throughout the world. Aiming at the dynamics of tidal flats, this dissertation firstly proposed a monitoring framework from three levels, including the pixel, object, and lifecycle. In addition, eleven events were defined to describe the dynamic activities throughout the lifecycles, which were captured, represented, and analyzed by utilizing graph theory. The Everglades in the southeastern corner of Florida Peninsula was selected to test this approach, which verifies an effective way to track, represent, and analyze the dynamic activities of tidal flats. Secondly, this dissertation mapped the distributions of tidal flats in the conterminous US, which provides a reliable dataset on a large spatiotemporal scale for future use. A random forest classification model was proposed, which uses 30 predictor variables to describe the spectral change patterns between the satellite images acquired in subsequent time steps. On the other hand, a total of 58,735 ground truth samples were collected under five classes, including permanent water, tidal flats, barren grounds, vegetated lands, and artificial surfaces. These sample points were randomly divided into two parts: 80% of them were used to train the random forest model, and the rest 20% were used to validate the results.

Show morePeat soils are known to be a significant emitter of atmospheric greenhouse gasses. However, the spatial and temporal variability in production and release of greenhouse gases (such as methane) in peat soils remains uncertain, particularly for low-latitude peatlands like the Florida Everglades, as the majority of studies on gas dynamics in peatlands focus on northern peatlands. The purpose of the work outlined here is focused on understanding the spatial and temporal variability in biogenic gas dynamics (i.e. production and release of methane and carbon dioxide) by implementing various experiments in the Florida Everglades at different scales of measurement, using noninvasive hydrogeophysical methods. Non-invasive methods include ground-penetrating radar (GPR), gas traps, time-lapse cameras, and hydrostatic pressure head measurements, that were constrained with direct measurements on soil cores like porosity, and gas composition using gas chromatography. By utilizing the measurements of in-situ gas volumes, we are able to estimate gas production using a mass balance approach, explore spatial and temporal variabilities of gas dynamics, and better constrain gas ebullition models. A better understanding of the spatial and temporal variability in gas production and release in peat soils from the Everglades has implications regarding the role of subtropical wetlands in the global carbon cycle, and can help providing better production and flux estimates to help global climate researchers improve their predictions and models for climate change.

Furthermore, most research work performed on peatlands has been focused on temperate to sub-arctic peatlands, while recent works have suggested that gas production rates from low-latitude peat soils are higher than those from colder climates. The purpose of the work proposed here is to introduce an autonomous Ground Penetrating Radar (GPR) method for investigating the timing of gas releases from peat soils at the lab scale utilizing samples originating from Maine and the Florida Everglades, and at the field scale in a Maine peatland. Geophysical data are supported by direct gas flux measurements using the flux chamber method enhanced by timelapse photography, and terrestrial LiDAR (TLS) monitoring surface deformation.

The Arcadia Formation is a mixed carbonate-siliciclastic rock unit that existed as a shallow carbonate ramp to platform environment during the Late Oligocene to Early Miocene Epoch. It can be divided into two distinct, informal sections based on lithological properties: the upper Arcadia Formation and lower Arcadia Formation. The sections are part of a major, third-order sequence that can be further divided into four higher-frequency, lower magnitude sequences: ARS1, ARS2, ARS3, and ARS4. The...
Show moreThe Arcadia Formation is a mixed carbonate-siliciclastic rock unit that existed as a shallow carbonate ramp to platform environment during the Late Oligocene to Early Miocene Epoch. It can be divided into two distinct, informal sections based on lithological properties: the upper Arcadia Formation and lower Arcadia Formation. The sections are part of a major, third-order sequence that can be further divided into four higher-frequency, lower magnitude sequences: ARS1, ARS2, ARS3, and ARS4. The sequence boundary separating ARS2 and ARS3 represents a drastic change in the depositional regime from a high-energy, inner ramp/platform to a lower-energy, deep outer ramp environment. ARS3 represents the period of maximum flooding and constitutes a major portion of the regressive system tract (RST) of the third order depositional sequence. In certain sections, the Arcadia Formation is heavily bioturbated including ichnotaxa from the glossifungites, cruziana, and scolithos inchofacies. Thalassinoides sp. burrows of the glossifungites ichnofacies were found to be commonly associated with firmground substrates and breaks in sedimentation. The lithofacies associations were grouped into paleodepositional environments that ranged from restricted marine to deep outer ramp with lithology ranging from grainstone to wackestone to mudstone with variable amounts of siliciclastic and phosphatic constituents. Each sequence boundary extends regionally south from Broward County to southern Miami-Dade County utilizing gamma-ray geophysical signatures unique to each sequence.

Show moreCoastal ecosystems, such as the salt marsh of the Georgia coast, have long been valued for decision-making purposes based on market-values of goods and services including: fishery landings, hedonic pricing of waterfront homes, and tourism dollars. These values do not show the full picture of services provided by these ecosystems. Using focus group discussions and key informant interviews I investigate socio-cultural values and benefits provided by salt marsh ecosystems in central coastal Georgia. Participants noted that through their experiences in marshes they developed a desire to be stewards. This desire, coupled with the industrial pollution, residential development, and sea-level rise threats in the area result in a need for cooperative conservation and thus better enforcement of existing regulations. This relational value persisted across geographic locations and sample populations. My results show the importance of utilizing diverse members of community to elicit qualitative value statements.

Show moreRefugee movements comprise one of the major forms of international migration in the world today. These movements are precipitated by a variety of inextricably linked factors, which make the prevention of such movements difficult. The three recognized solutions to the global refugee crisis are repatriation, local integration, and third-country resettlement. This thesis focuses on the resettlement of African refugees in the United States. Ethiopians are the largest African group to settle in the United States and they are more widely dispersed than all other African refugee groups in the United States. Their spatial distribution coincides with the regional distribution of refugee sponsors and voluntary agencies that help in the resettlement of refugees. Secondary migration of African refugees is a reflection of the availability of economic and educational opportunities, as well as the presence of a large ethnic community.

Show moreIn southeastern Florida, the majority of drinking water comes from the Biscayne aquifer. This aquifer is comprised of heterogeneous limestones, sandstones, sand, shell and clayey sand with zones of very high permeability. Visualizing the spatial variations in lithology, porosity and permeability of heterogeneous aquifers, like the Biscayne, can be difficult using traditional methods of investigation. Using the Roxar IRAP RMS software multi-layered 3D conceptual geomodels of the lithology, cyclostratigraphy and porosity were created in a portion of the Biscayne aquifer. The models were built using published data from borehole geophysical measurements, core samples, and thin sections. Spatial relations between lithology, cyclostratigraphy, porosity, and preferential flow zones were compared and contrasted to better understand how these geologic features were inter-related. The models show local areas of differing porosity within and cross-cutting different cycles and lithologies. Porosity in the Biscayne aquifer study area follows a hierarchy attributed to lithofacies with a pattern of increasing porosity for the high frequency cycles. This modeling improves understanding of the distribution and interconnectedness of preferential flow zones, and is thus an invaluable tool for future studies of groundwater flow and groundwater contamination in the Biscayne aquifer.

Show moreWater treatment facilities across the United States are known for providing high-quality drinking water to their residents. However, differences in treatment methods, aging infrastructure, and outdated household plumbing may affect the quality of drinking water by the time it reaches the consumer’s tap. Palm Beach County, Florida, is an area with large socioeconomic contrasts where some families live in dilapidated structures and others reside in luxurious, gated communities. This research highlights the variation of household water quality by determining metal concentrations in tap water samples in communities of different socioeconomic status. In addition, interviews were conducted with personnel from five different Water Treatment Plants (WTPs) in the study area to understand the relationship between customers and their water utility. Results indicate that effective communication strategies are needed to boost public trust and fill critical information gaps about the water treatment process. Ninety-six tap water samples were collected from households throughout eastern Palm Beach County and analyzed for different metals using Inductively Coupled Plasma Optical Emission Spectrometry. Surveys were also administered at the same households where tap water samples were collected. Residents were asked about their perceptions of tap water and social and economic questions regarding their household characteristics. A Socioeconomic Status (SES) index was created using Principal Components Analysis (PCA) to understand how perceptions of tap water quality and concentrations of metals in household tap water vary based on SES. Results provide evidence that those living in the lowest-ranking SES neighborhoods are the least satisfied with their tap water quality and consume less tap water than those living in higher SES neighborhoods. Water quality results highlighted large variations in concentrations of aluminum (Al) and thus, analyses focused specifically on how Al concentrations varied according to SES. Results from Ordinary Least Squares regression show that as socioeconomic status decreases, the concentration of Al in tap water increases. Six samples exceed the State of Florida’s Secondary Maximum Contaminant Level (SMCL) for Al, and five of those samples were found in the lowest-ranking SES neighborhoods (SES 1 and 2). The results of this research provide evidence that inequities in household water quality exist across eastern Palm Beach County, Florida.

This study of contaminant hydrogeology examined conditions at a former golf course in Florida with known arsenic contamination, and included a detailed examination of existing assessment data for the study area, an experimental pumping test with groundwater sampling, examination of sediment cores, and a preliminary geophysical investigation. The primary purpose was to determine what the existing controls are on As mobility. The primary findings were that redox conditions did have an effect on As concentrations. Groundwater in the study area is generally reducing, but during the pumping test was generally oxidizing. No potential As sources were definitively identified, and the most likely source remains anthropogenic, but interactive conditions with Fe, Mn, NO3-N, and S remain nebulous.

Show moreThis work examined the role of the craft brewers of Florida in creating alternative economies. This work argues that craft brewers function in ways that they can create a space in which other, smaller entities might then take advantage. Craft breweries' expansion, and continued success rests on the ability of the brewer to harness the power of transformation, the prism effect, or the refaceting of a space with different meanings. Craft breweries meet many of Jacobs' (1961), as stated in her seminal work, conditions for diversity in the city, especially in the role of self-government. Craft brewers function as informal forms of government for communities, by making smaller entities more visible, by serving as a warrior and weaver for political action in the city, and offering subversive defiance, by which they subtly challenge the dominant disconnected economic structure. Craft breweries serve as a way to create an embedded economy, or as a way of grounding local businesses, social issues, and individual actors together. In this way, the research addressed deeper ethical issues that transcend the idea of craft brewing in general, that the success of craft brewers reflects a form of activism, and a visible way for individuals to circumvent the global processes which left them disengaged in their community.

Show moreEach year storms impact coastal areas, sometimes causing significant morphologic change. Cold fronts are associated with increased wave energy and frequently occur during the winter months along many coasts, such as the Atlantic and Gulf of Mexico. The higher wave energy can be responsible for a large quantity of the sediment transport resulting in rapid morphologic change. Using streamer traps, the vertical distribution of onshore-directed sediment transport during two different cold fronts on two low-wave energy beaches (i.e., along the northern Yucatan and southeast Florida) were compared with the resulting morphologic change. The objectives of this study are to: 1) analyze the grain size distribution (statistics) of sediment transported during a cold front, 2) compare the vertical sediment distribution throughout the water column, and 3) compare characteristics of bed sediment to the sediment within the water column. Understanding the changing grain size distribution of bottom sediments in comparison to directional transport (throughout the water column) should help determine the sediment fraction(s) being eroded or deposited, which could greatly improve predictions of storm-induced morphology change.

Show moreThe federal Low Income Housing Tax Credit (LIHTC) program, authorized in 1986, has gained recognition over the last decade as America's largest place-based subsidized housing production program. The Qualified Census Tract (QCT) provision of the LIHTC program awards developers for projects built in high-poverty neighborhoods. This research examines whether the QCT provision is deconcentrating poverty or instead perpetuating it by comparing QCTs with LIHTC projects against QCTs with no LIHTC projects. In this study, a socioeconomic index is created to examine changes in socioeconomic variables (poverty, income, unemployment, and education) using 1990 Decennial Census data and 2005-2009 American Community Survey data for the twenty most populated MSAs in the United States to determine how LIHTC projects have changed the landscape of poverty in urban QCTs. Control and target groups were established to analyze the impact of LIHTC projects in QCTs. The control group consists of QCTs with no LIHTC projects and the target group contains QCTs with LIHTC projects. In order to determine how the socioeconomic variables have changed over the last fifteen years, the percent change from 1990 to 2005-2009 was calculated for each tract. Independent Sample T-tests were conducted at the national level, MSA level, and county level (when the sample size was large enough) using SPSS to determine if the difference in the target group's derived socioeconomic index and variables were significantly different from the control group. The findings indicate the target groups overwhelmingly outperformed the control groups for the socioeconomic index and every variable except unemployment. The results of this study may be valuable for policymakers to develop thresholds and guidelines for future LIHTC development in areas concentrated by poverty.

- Abstract/Description
-
An underwater survey was performed between July 1987 and August 1990 focusing on the entire nearshore reef tract situated along the shoreline of Palm Beach County, Florida. Transects, aligned on Florida Department of Natural Resources survey monuments, commenced from the high water mark waterward to the 4 meter isobath. A total of 125 of the 228 transects were found to contain nearshore reefs. A matrix of reef characteristics was created based upon the value of six indices including reef...

Transects, aligned on Florida Department of Natural Resources survey monuments, commenced from the high water mark waterward to the 4 meter isobath. A total of 125 of the 228 transects were found to contain nearshore reefs. A matrix of reef characteristics was created based upon the value of six indices including reef width and profile, biodiversity, beach width, public access and an assessment of the historical permanence of the reef. This matrix, based on "z" scores, provided a means of comparing each nearshore reef transect station within the County. This evaluative scheme was used to develop recommendations for the protection and management of the nearshore reefs.

- Abstract/Description

This paper analyzes a high density housing project in terms of its defensible space. The behavior of residents of Citrus Park Homes was seen as indicative of tenant attitudes toward their home project, its sense of community, of safety and security, and pride of ownership. Analysis of this privately-owned project includes a description of the physical structure, spatial characteristics, tenant characteristics and tenant attitudes, as evidenced in interviews with 83 adult residents. Where poor...

The behavior of residents of Citrus Park Homes was seen as indicative of tenant attitudes toward their home project, its sense of community, of safety and security, and pride of ownership. Analysis of this privately-owned project includes a description of the physical structure, spatial characteristics, tenant characteristics and tenant attitudes, as evidenced in interviews with 83 adult residents. Where poor spatial design and physical structure are evidenced by poor behavior and attitude (lack of recognition or acceptance of territory) changes in the spatial or architectural design were suggested.

- Abstract/Description

Shorelines are a primary source of attraction for the nearly two million tourists who visit Palm Beach County annually. Many of Palm Beach County beaches are located on barrier islands, separated by a series of inlets which serve as access points to the Intracoastal Waterway. However, inlets are often cited as a source of erosion, through interruption of littoral drift and interaction with nearshore hydrodynamics (e.g., causing wave diffraction or refraction). In an effort to mitigate...
Show moreShorelines are a primary source of attraction for the nearly two million tourists who visit Palm Beach County annually. Many of Palm Beach County beaches are located on barrier islands, separated by a series of inlets which serve as access points to the Intracoastal Waterway. However, inlets are often cited as a source of erosion, through interruption of littoral drift and interaction with nearshore hydrodynamics (e.g., causing wave diffraction or refraction). In an effort to mitigate potential negative impacts of the economically important tidal inlets, Palm Beach County has installed a sand transfer plant (STP) at two inlet locations, the Lake Worth Inlet and the South Lake Worth Inlet. Through analysis of annual aerial photography and beach profile surveys taken between 2000 and 2009, this study will determine what effect, if any, these sand transfer plants are having on the inlet-adjacent shorelines north and south of the two inlets with STP, as well as an inlet without an STP (Boca Inlet). This study hopes to increase the understanding of shoreline dynamics in Palm Beach County, which could recognize important alongshore patterns, such as the occurrence of erosional hot spots, to assist in future mitigation efforts.

- Abstract/Description
-
The legacy of monosodium methanearsenate (MSMA) application to golf courses is often arsenic concentrations above the EPA’s maximum contaminant level of 10 μg/L for drinking water and the FDEP soil cleanup target level of 2.1 mg/kg for residential areas. These concentrations pose a health risk and must be remediated for residential development. The objective of this study was to determine how arsenic concentrations vary spatially at a closed golf course poised for residential development....
Show moreThe legacy of monosodium methanearsenate (MSMA) application to golf courses is often arsenic concentrations above the EPA’s maximum contaminant level of 10 μg/L for drinking water and the FDEP soil cleanup target level of 2.1 mg/kg for residential areas. These concentrations pose a health risk and must be remediated for residential development. The objective of this study was to determine how arsenic concentrations vary spatially at a closed golf course poised for residential development. Groundwater and sediment arsenic concentrations were quantified and the controls on arsenic (As) mobility were characterized. The presence of nitrates and iron-(hydr)oxides at the studied golf course largely influenced putting greens having the least As in groundwater whereas roughs contained the most.
