Scientists compared oil biodegradation model parameters and ran simulations to understand the relative importance of variables that affect predictions for oil fate from a deep-water release.
Scientists compared how different surfactants affect bacterial adhesion to oil droplets (20−60 μm), which is necessary for biodegradation.
Petroleum hydrocarbons buried in sandy beaches are protected from tides and UV light and, thus, may persist longer in the environment than oil on the beach surface.
Petroleum hydrocarbons released by oil spills can accumulate on beaches and in nearshore sediments, potentially creating health risks for humans and coastal organisms. However, the highly variable conditions of beach environments make it difficult to determine the long-term behavior and fate of hydrocarbons in sands and sediment.
Eight years after Deepwater Horizon, we reflect on the extraordinary establishment of the largest coordinated scientific endeavor around an ocean event – the Gulf of Mexico Research Initiative (GoMRI) – to understand, respond to, and mitigate impacts from this and future oil spills.
Scientists conducted laboratory experiments to examine the influence of moon jellyfish (Aurelia aurita) on crude oil aggregation and degradation. The researchers found that jellyfish swimming in a dispersed oil solution produced copious amounts of mucus which formed aggregates containing 26 times more oil than the surrounding water.
The Deepwater Horizon oil spill and the remediation efforts that followed raised many concerns about impacts on coastal and ocean environments.
Scientists at the Hamburg University of Technology conducted high-pressure biodegradation experiments simulating conditions at the Deepwater Horizon site.
