University of Florida newsletter published September 16, 2014: Research team headed by UF professor found evidence of oil residue in Gulf two years after BP spill By Jean Feingold

horizonGAINESVILLE, Fla. — Oil residue remained in the Gulf of Mexico two years after the Deepwater Horizon oil spill, according to a study headed by a University of Florida professor. A team lead by professor Thomas S. Bianchi, who holds the Jon and Beverly Thompson Endowed Chair of Geological Sciences, analyzed water samples taken from Gulf waters in 2012 and concluded that dispersants intended to speed the breakup of the oil and hasten its decomposition appear to have enhanced the oil’s solubility in water, resulting in a shift in the optical properties of the oil and its degradation into smaller hydrocarbon molecules. Bianchi and researchers from three other universities examined samples collected from the deep Gulf region around the 2010 spill, looking for evidence of a chemical signature. While other researchers have concluded that hydrocarbons in deep Gulf waters resulting from the explosion no longer are detectable by standard chemical analyses, the UF team found evidence that some of the oil had been converted into a different pool of molecules that also were part of the natural ecosystem…
