Marine ecosystems provide many valuable resources for humans, including seafood and petroleum. Conservation policies that protect marine ecosystems, especially pollution and petroleum-related policies, depend on accurate scientific data about the ways different marine species experience pollution.
The microbial community living in fish’s gastrointestinal tracts, also called the gut microbiome, are vital to their developing immune systems and can influence behaviors such as foraging.
Crude oil contains tens of thousands of hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs) that create unique chemical fingerprints for different types of oil. Dawei “David” Shi uses geochemical analysis techniques in mesocosm studies to track these fingerprints.
Scientists analyzed sediment cores from two sites near the Macondo wellhead to characterize possible spill impacts on benthic foraminifera (single celled organisms with a hard shell). The team found elevated Polycyclic Aromatic Hydrocarbon (PAH) concentrations and a significant decrease in density and species diversity for foraminifera.
Researchers measured polycyclic aromatic hydrocarbon (PAH) concentrations in water collected near the Deepwater Horizon site to understand how sinking particles, such as marine snow, influence the residence time of PAHs in the upper ocean.
Texas A&M University scientists analyzed data made publically-available by BP for 20,000+ water samples collected from 13,000 stations during and after the 2010 spill. They found that oil occurrence was patchy with only about 20% of the samples having hydrocarbon levels above pre-spill background conditions.
Louisiana State University scientists assessed wetland soils for changes in oil compound levels before and after oil from the Deepwater Horizon blowout reached Louisiana marshes.
Susan Snyder’s experiences researching fish bile have shown her an overwhelming truth: to solve complex problems, one simply cannot work alone.
Scientists from the University of West Florida found that Coquina clams could be used to detect biologically available oil in Florida surf zones.
