Use Of Spectrofluorometry To Detect Petroleum Hydrocarbons In The Marine Environment, Mary Iris Abercrombie
Use Of Spectrofluorometry To Detect Petroleum Hydrocarbons In The Marine Environment, Mary Iris Abercrombie
USF Tampa Graduate Theses and Dissertations
The genesis of this research was the Deepwater Horizon oil spill, which discharged petroleum and gas into the Gulf of Mexico for 87 days in 2010. High-resolution fluorescence spectroscopy was employed for the detection of petroleum in seawater samples following the oil spill. Fluorescence arises from the chemical structure of π-bonding in C=C bonds, especially those in aromatic structures. Spectrofluorometry was also used to observe and track the formation of petroleum plumes in seawater undergoing controlled physical dispersion in a wave tank, both with and without the addition of chemical dispersant. Further, the changing fluorescence characteristics of a broad range …
Improving The Integration Of Restoration And Conservation In Marine And Coastal Ecosystems: Lessons From The Deepwater Horizon Disaster, Richard L. Wallace, Gilbert Gilbert, John E. Reynolds Iii
Improving The Integration Of Restoration And Conservation In Marine And Coastal Ecosystems: Lessons From The Deepwater Horizon Disaster, Richard L. Wallace, Gilbert Gilbert, John E. Reynolds Iii
C-IMAGE Publications
In the wake of the Deepwater Horizon disaster, much has been learned about the biological, ecological, physical, and chemical conditions of the Gulf of Mexico. In parallel, the research community has also gained insight about the social and organizational structures and processes necessary for oil spill response and subsequent marine and coastal restoration. However, even with these lessons from both the Deepwater Horizon and previous spills, including 1989’s Exxon Valdez and the Ixtoc 1 in 1979, our understanding of how to avoid future crises has not advanced at the same pace as offshore oil and gas development. We argue that …
Three-Dimensional Daily Hindcast Of Oil Concentrations And Oil Mass Estimates From The Far-Field Modeling Of A Deep Water Spill Scenario In The Northwest African Continental Shelf, Using The Connectivity Modeling System On A Probabilistic Approach, Claire B. Paris, Natalie Perlin, Ana C. Vaz
Three-Dimensional Daily Hindcast Of Oil Concentrations And Oil Mass Estimates From The Far-Field Modeling Of A Deep Water Spill Scenario In The Northwest African Continental Shelf, Using The Connectivity Modeling System On A Probabilistic Approach, Claire B. Paris, Natalie Perlin, Ana C. Vaz
C-IMAGE data
The dataset contains the numerical results of probabilistic forecasts for possible oil spills in the Northwest African continental Shelf, around Senegal. The origin of possible oil spills scenarios are deep wells proposed to operate in and around Cayar Canyon (Senegal). Oil dispersal and concentrations were simulated using the latest updated version of the oil application of the Connectivity Modeling System (CMS) or oil- CMS. In this version, the specified hydrocarbon pseudo-components are in the same droplet. The post-processing analysis yielded 4-D spatiotemporal data of the oil concentrations and oil mass on a regular horizontal and vertical grid, as well as …

Associations Between Chronic Exposure To Polycyclic Aromatic Hydrocarbons And Health Indices In Gulf Of Mexico Tilefish (Lopholatilus Chamaeleonticeps) Post Deepwater Horizon, Susan M. Syder, Erin Pulster, Steven Murawski
C-IMAGE Publications
A time series of polycyclic aromatic hydrocarbon (PAH) data was collected for Gulf of Mexico demersal fishes in the years following the Deepwater Horizon oil spill (2012–2017). Tilefish (Lopholatilus chamaeleonticeps ) were sampled via demersal longline at repeat stations in the northern Gulf of Mexico in 2012 to 2015 and 2017. Bile samples (n = 256) were analyzed via high‐performance liquid chromatography with fluorescence detection for PAH metabolites as a biomarker of exposure to PAHs. Liver tissues (n = 230) were analyzed for accumulation of PAHs and alkylated homologs via quick, easy, cheap, effective, rugged, and safe …

Dispersant Enhances Hydrocarbon Degradation And Alters The Structure Of Metabolically Active Microbial Communities In Shallow Seawater From The Northeastern Gulf Of Mexico, Xiaoxu Sun, Lena Chu, Elisa Mercando, Isabel Romero, David Hollander, Joel E Kostka
C-IMAGE Publications
Dispersant application is a primary emergency oil spill response strategy and yet the efficacy and unintended consequences of this approach in marine ecosystems remain controversial. To address these uncertainties, ex situ incubations were conducted to quantify the impact of dispersant on petroleum hydrocarbon (PHC) biodegradation rates and microbial community structure at as close as realistically possible to approximated in situ conditions [2 ppm v/v oil with or without dispersant, at a dispersant to oil ratio (DOR) of 1:15] in surface seawater. Biodegradation rates were not substantially affected by dispersant application at low mixing conditions, while under completely dispersed conditions, biodegradation …
