Longitudinal Assessment Of Shifting Microbial Community Composition In Sandy Beaches Following The 2010 Deepwater Horizon Oil Spill And Remediation Efforts, Axita Ajaykumar Gupta

LSU Master's Theses

Sandy beaches are geological zones parallel to the shoreline where high energy, open ocean unconsolidated sediments are deposited and reworked. Sandy beaches represent critical ecosystems that support a wide variety of underappreciated biodiversity. Prior to the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, the diversity and function of microbial communities in supratidal beach sediments along the Gulf of Mexico coastlines were not well understood. It was unclear if possible community compositional changes would occur during and following exposure to oil, or what impact the remediation efforts, such as sand washing, would have to the microbial communities and …
