Using Ecosystem-Based Modeling To Describe An Oil Spill And Assess The Long-Term Effects, Lindsey N. Dornberger
Using Ecosystem-Based Modeling To Describe An Oil Spill And Assess The Long-Term Effects, Lindsey N. Dornberger
USF Tampa Graduate Theses and Dissertations
The goal of the research conducted in this dissertation was to define and test methods to incorporate oil spill effects into an ecosystem-based assessment model. It was instigated by the Deepwater Horizon oil spill, an unprecedented oil spill in the United States for both depth and volume, with unknown implications for the health of the region. Using an ecosystem-based assessment model like Atlantis, with integrated oil spill dynamics, was the ideal candidate to predict long-term impacts such as decreased abundance or population recovery time. However no previous methodology existed for doing so in any ecosystem-based assessment model. Therefore, first I …

Spatial Dynamics And Productivity Of A Gulf Of Mexico Commercial Reef Fish Fishery Following Large Scale Disturbance And Management Change, Marcy Lynn Cockrell
USF Tampa Graduate Theses and Dissertations
The Gulf of Mexico commercial reef fish fishery has experienced significant management changes and disturbance in recent years, including transitioning two major fisheries from a traditional open access system into a limited entry individual fishing quota (IFQ) system in 2007 and 2010. Also in 2010, the Deepwater Horizon oil spill (DWH) released an estimated 4.9 million barrels of oil into the Gulf (~206 million U.S. gallons), and is still the largest U.S. environmental disaster to date. Emergency fishing closures initiated shortly after the oil spill began were successful in keeping tainted seafood from reaching markets. However, effects of DWH closures …
