Indigenous Water Justice Symposium (June 6)

Indigenous peoples throughout the world face diverse and often formidable challenges of what might be termed “water justice.” On one hand, these challenges involve issues of distributional justice that concern Indigenous communities’ relative abilities to access and use water for self-determined purposes. On the other hand, issues of procedural justice are frequently associated with water allocation and management, encompassing fundamental matters like representation within governance entities and participation in decision-making processes. Yet another realm of water justice in which disputes are commonplace relates to the persistence of, and respect afforded to, Indigenous communities’ cultural traditions and values surrounding water—more specifically, …

A compiled set of in situ data is important to evaluate the quality of ocean-colour satellite-data records. Here we describe the data compiled for the validation of the ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI). The data were acquired from several sources (MOBY, BOUSSOLE, AERONET-OC, SeaBASS, NOMAD, MERMAID, AMT, ICES, HOT, GeP&CO), span between 1997 and 2012, and have a global distribution. Observations of the following variables were compiled: spectral remote-sensing reflectances, concentrations of chlorophyll a, spectral inherent optical properties and spectral diffuse attenuation coefficients. The data were from multi-project archives acquired via the open internet …

Aqueous Photochemistry Of Glyoxylic Acid, Alexis J. Eugene, Sha-Sha Xia, Marcelo I. Guzman

Chemistry Faculty Publications

Aerosols affect climate change, the energy balance of the atmosphere, and public health due to their variable chemical composition, size, and shape. While the formation of secondary organic aerosols (SOA) from gas phase precursors is relatively well understood, studying aqueous chemical reactions contributing to the total SOA budget is the current focus of major attention. Field measurements have revealed that mono-, di-, and oxo-carboxylic acids are abundant species present in SOA and atmospheric waters. This work explores the fate of one of these 2-oxocarboxylic acids, glyoxylic acid, which can photogenerate reactive species under solar irradiation. Additionally, the dark thermal aging …

Investigating The Potential Of Land Use Modifications To Mitigate The Respiratory Health Impacts Of No2: A Case Study In The Portland-Vancouver Metropolitan Area, Meenakshi Rao

Dissertations and Theses

The health impacts of urban air pollution are a growing concern in our rapidly urbanizing world. Urban air pollutants show high intra-urban spatial variability linked to urban land use and land cover (LULC). This correlation of air pollutants with LULC is widely recognized; LULC data is an integral input into a wide range of models, especially land use regression models developed by epidemiologists to study the impact of air pollution on human health. Given the demonstrated links between LULC and urban air pollution, and between urban air pollution and health, an interesting question arises: what is the potential of LULC …

Coastal Ocean And Shelf-Sea Biogeochemical Cycling Of Trace Elements And Isotopes: Lessons Learned From Geotraces, Matthew A. Charette, Phoebe J. Lam, Maeve C. Lohan, Eun Young Kwon, Vanessa Hatje, Catherine Jeandel, Alan M. Shiller, Gregory A. Cutter, Alex Thomas, Philip W. Boyd

OES Faculty Publications

Continental shelves and shelf seas play a central role in the global carbon cycle. However, their importance with respect to trace element and isotope (TEI) inputs to ocean basins is less well understood. Here, we present major findings on shelf TEI biogeochemistry from the GEOTRACES programme as well as a proof of concept for a new method to estimate shelf TEI fluxes. The case studies focus on advances in our understanding of TEI cycling in the Arctic, transformations within a major river estuary (Amazon), shelf sediment micronutrient fluxes and basin-scale estimates of submarine groundwater discharge. The proposed shelf flux tracer …

Carbon Nanotubes Affect The Toxicity Of Cuo Nanoparticles To Denitrification In Marine Sediments By Altering Cellular Internalization Of Nanoparticle, Xiong Zheng, Yinglong Su, Yinguang Chen, Rui Wan, Mu Li, Haining Huang, Xu Li

Department of Civil and Environmental Engineering: Faculty Publications

Denitrification is an important pathway for nitrate transformation in marine sediments, and this process has been observed to be negatively affected by engineered nanomaterials. However, previous studies only focused on the potential effect of a certain type of nanomaterial on microbial denitrification. Here we show that the toxicity of CuO nanoparticles (NPs) to denitrification in marine sediments is highly affected by the presence of carbon nanotubes (CNTs). It was found that the removal efficiency of total NO_X⁻-N (NO₃⁻-N and NO₂⁻-N) in the presence of CuO NPs was only 62.3%, but it …

An Early Assessment Of Medium Range Monsoon Precipitation Forecasts From The Latest High-Resolution Ncep-Gfs (T1534) Model Over South Asia, Satya Prakash, Imaranali M. Momin, Ashis K. Mitra, Partha S. Bhattacharjee, Fanglin Yang, Vijay Tallapragada

Publications and Research

Reliable prediction of the South Asian monsoon rainfall and its variability is crucial for various hydrological applications and early warning systems. The National Centers for Environmental Prediction – Global Forecast System (NCEP–GFS) is one of the popular global deterministic numerical weather prediction models, which is recently upgraded from T574 to T1534. In this paper, medium range monsoon precipitation forecasts from both the T1534 and T574 models are critically evaluated over the South Asia for the peak monsoon months (July and August) of 2015. Although both the versions of GFS model show similar large-scale monsoon rainfall patterns, the dry bias over …

Bathymetric Survey For Lakes Azuei And Enriquillo, Hispaniola, Michael Piasecki, Mahrokh Moknatian, Fred Moshary, Joseph Cleto, Yolanda Leon, Jorge Gonzalez, Daniel Comarazamy

Publications and Research

The two largest lakes on the Caribbean Island of Hispaniola, Lake Azuei in Haiti and Lake Enriquillo in the Dominican Republic, have experienced dramatic growth and surface area expansion over the past few years leading to severe flooding and loss of arable land around the lake perimeters. In order to better understand the reasons for this unprecedented rate of expansion and the resulting consequences a multi-disciplinary team comprised of researchers from Haiti, the DR, and the US have embarked on an extensive data collecting and hydrologic and climatological modeling campaign. While the sensor deployment entails stations that measure climatological data …

In-Air Hearing Of A Diving Duck: A Comparison Of Psychoacoustic And Auditory Brainstem Response Thresholds, Sara E. Crowell, Alicia M. Wells-Berlin, Ronald E. Therrien, Sally E. Yannuzzi, Catherine E. Carr

United States Geological Survey: Staff Publications

Auditory sensitivity was measured in a species of diving duck that is not often kept in captivity, the lesser scaup. Behavioral (psychoacoustics) and electrophysiological [the auditory brainstem response (ABR)] methods were used to measure in-air auditory sensitivity, and the resulting audiograms were compared. Both approaches yielded audiograms with similar U-shapes and regions of greatest sensitivity (2000-3000 Hz). However, ABR thresholds were higher than psychoacoustic thresholds at all frequencies. This difference was least at the highest frequency tested using both methods (5700 Hz) and greatest at 1000 Hz, where the ABR threshold was 26.8 dB higher than the behavioral measure of …

Applications Of Satellite Geodesy In Environmental And Climate Change, Qian Yang

USF Tampa Graduate Theses and Dissertations

Satellite geodesy plays an important role in earth observation. This dissertation presents three applications of satellite geodesy in environmental and climate change. Three satellite geodesy techniques are used: high-precision Global Positioning System (GPS), the Gravity Recovery and Climate Experiment (GRACE) and Interferometric Synthetic Aperture Radar (InSAR). In the first study, I use coastal uplift observed by GPS to study the annual changes in mass loss of the Greenland ice sheet. The data show both spatial and temporal variations of coastal ice mass loss and suggest that a combination of warm atmospheric and oceanic condition drove these variations. In the second …

Surface Dynamics Of Crude And Weathered Oil In The Presence Of Dispersants: Laboratory Experiment And Numerical Simulation, Alexander Soloviev, Brian K. Haus, Michael G. Mcgauley, Cayla Whitney Dean, David G. Ortiz-Suslow, Nathan J. M. Laxague, Tamay M. Ozgokmen

Marine & Environmental Sciences Faculty Articles

Marine oil spills can have dire consequences for the environment. Research on their dynamics is important for the well-being of coastal communities and their economies. Propagation of oil spills is a very complex physical-chemical process. As seen during the Deepwater Horizon event in the Gulf of Mexico during 2010, one of the critical problems remaining for prediction of oil transport and dispersion in the marine environment is the small-scale structure and dynamics of surface oil spills. The laboratory experiments conducted in this work were focused on understanding the differences between the dynamics of crude and weathered oil spills and the …

Abundance And Diversity Of Deep-Sea Crustaceans Of Bear Seamount, New England Seamount Chain, Valerie Miranda

HCAS Graduate Science Research Symposium

Bear Seamount (39° 55’ N; 67° 30’ W) is the westernmost peak of extinct undersea volcanoes in the New England Seamount Chain (Moore et al., 2003). It is located on the continental slope off Georges Bank, and is governed by unique environmental factors and currents that may be unlike those of the other seamounts (Moore et al., 2003). Previous cruises to this seamount have been successful in capturing abundant fishes, cephalopods and invertebrates (Moore et al., 2003; Moore et al., 2004; Moore et al., 2008), but only the distribution patterns of the fishes and cephalopods have been examined, leaving a …

Vision And Bioluminescence In Deep-Sea Crustaceans, Tamara Frank

HCAS Graduate Science Research Symposium

Adaptations of the visual systems of deep-sea crustaceans to dim light environments are driven not only by environmental light, but also biologically produced light, or bioluminescence. In the pelagic zone, the relationship is driven, at least in part, by intrinsic bioluminescence. The unusual possession of UV sensitivity, in additional to the expected blue sensitivity, in several species of deep-sea crustaceans appears to be linked to their two modes of bioluminescence. In the benthic zone, the relationship is not so clear. On several NOAA-OER funded research expeditions, electrophysiological studies were conducted on a number of species of decapod crustaceans collected with …

Characterization Of The Marine Sponge Amphimedon Compressa Microbiome Across A Spatial Gradient, Renee Michelle Potens

HCNSO Student Theses and Dissertations

Diverse and ecologically important microbial communities (microbiomes) are symbiotic within marine sponges. In this study, the microbiome of Amphimedon compressa from three sample locations (Broward and Dade Counties, Southeast Florida, USA and the Southern Caribbean, Bocas del Toro, Panama) is characterized using 16S rRNA Illumina sequencing. The predominant taxa are Proteobacteria and Cyanobacteria, as expected for Low Microbial Abundance sponges, accounting for over 53% of the total microbiome community. The numbers of Operational Taxonomic Units (OTUs) decrease from Broward County (2,900) to Dade County (2,300) and then Bocas del Toro (1,200). The correlates to a decreasing north-south gradient of …

Northern San Francisco Bay Ecological Risk Assessment: Potential Crude By Rail Incident, Meagan Bowis

Master's Projects and Capstones

Oil spill models, ecological risks, response options, and costs were assessed for a discharge of Bakken crude oil into the Northern San Francisco Bay from a train derailment. This assessment was based on the risk of crude by rail derailments into the San Francisco Bay; in 2014, California oil refineries imported over 240 million gallons of Bakken crude oil by rail for processing. A hypothetical scenario was developed from a derailment on the Union Pacific Railroad Bridge and discharging 100,000 gallons of Bakken crude oil into the Northern San Francisco Bay. The oil trajectory impacted the Carquinez Strait, Suisun, San …

Monitoring A Problem: Evaluating The Ecological Status Of The Invasive Nile Monitor In Florida And Forecasting Population Expansion Using Computational Gis, Noah Cohen

HCAS Graduate Science Research Symposium

The state of Florida is an epicenter for the introduction of exotic terrestrial and marine species, often which are attributed to the pet industry. Identifying the threats posed by exotics that may become invasive is critical to manage and protect indigenous species and habitats. One such exotic that is now invasive in Florida is the Nile Monitor (Varanus niloticus). The Nile monitor is a large, predatory lizard native to central and southern Africa that is thought to have been introduced to Florida via both intentional and unintentional releases associated with the exotic pet trade. Since their introduction, Nile monitors have …

HCAS Graduate Science Research Symposium

The genome assembly and annotation of Asian seabass (Lates calcarifer) , a marine teleost with aquaculture relevance will be described, an initiative of Genome 10K . Though > 500 eukaryotic genome sequences are available in public repositories, the majority are highly fragmented with incomplete assemblies, so considerable effort and resources are often spent to improve their quality. In the present study, PacBio long read sequencing , genetic and optical mapping, and syntenic inference were combined to build a chromosome-length assembly with a contig N50 size over 1 Mb and scaffold N50 size over 25 Mb that span ~90% of the genome …

If You Build It, Will They Come? Exploring Enhancements To Artificial Structure For Use In Restoration And Mitigation Applications In The Mexican Caribbean, Kirk Kilfoyle

HCAS Graduate Science Research Symposium

A study involving standardized artificial reef modules (ReefballsTM) was conducted in Puerto Morelos, Mexico. The purpose was to explore the use of artificial structure in restoration and mitigation projects in a Caribbean coral reef environment similar to South Florida by applying select experimental treatments hypothesized to accelerate their acquisition of a natural coral reef assemblage. Multiple hypotheses on the progression and interaction between artificial structure and the resulting fish, coral, algal, and non-coral invertebrate assemblages were examined. Each of 40 reefball modules received one of 4 treatments (10 modules/treatment): invertebrate substrate pads, coral transplants, settlement plates, or control. Following deployment, …
