July 14, 2015 -- An international science team investigated the effects of weathering of petroleum biomarkers on the reliability of these compounds for fingerprinting Macondo oil. They identified individual biomarkers that were resistant to weathering processes and others that were depleted by these processes. Most biomarkers were suitable to identify Macondo oil up to 28 months post spill. Read more...
July 9, 2015 -- Scientists measured the natural abundance of radiocarbon (14C) in sediments near the Deepwater Horizon spill site and estimated the location and amount of carbon derived from crude oil or gas. Their best estimate was that oil-derived carbon equivalent to 3 – 4.9 percent of reported oil from the 2010 spill may be accounted for by carbon found in the sediments. Read more...
May 26, 2015 -- A team of scientists from Eckerd College and University of South Florida conducted a time-series sediment study to better understand impacts from the Deepwater Horizon oil spill. Three years post-spill, they found a continued state of altered geochemical conditions in sediment near the spill site. Concentrations of manganese, rhenium, and cadmium in sediment indicated a large organic carbon influx and subsequent decreases in oxygen concentrations. Read more...
April 20, 2015 -- April 20 marked five years since BP's oil rig Deepwater Horizon dumped millions of gallons of crude into the Gulf. Even though Florida didn't get the worst of the catastrophe, the state is still feeling the effects. The spill killed 11 workers and dumped more than 130 million gallons of crude into the Gulf five years ago. Florida State Professor Ian MacDonald was at the forefront of estimating the amount of oil being spilled into the ocean. He says restoration is a long way from completion. . Read more...
