The Deepwater Horizon oil spill is unparalleled among environmental hydrocarbon releases, because of the tremendous volume of oil, the additional contamination by dispersant, and the oceanic depth at which this release occurred. Here, we present data on general toxicity and mutagenicity of upper water column waters and, to a lesser degree, sediment porewater of the Northeastern Gulf of Mexico (NEGOM) and west Florida shelf (WFS) at the time of the Deepwater Horizon oil spill in 2010 and… Expand

Comment on "Toxicity and mutagenicity of Gulf of Mexico waters during and after the deepwater horizon oil spill".
TLDR
Paul et al. imply that the spill has a major lingering acute toxicity, but they neglect the following: the magnitudes of field responses under documented field exposures are inconsistent with the much higher exposures required to demonstrate such responses; field samples exhibited stimulatory effects of the same magnitude as samples judged to be toxic, seriously questioning the precision and accuracy of the tests for delineating toxicity gradients.

Microbial responses to the Deepwater Horizon oil spill: from coastal wetlands to the deep sea.
TLDR
Results have shown an unexpectedly rapid response of deep-sea Gammaproteobacteria to oil and gas and documented a distinct succession correlated with the control of the oil flow and well shut-in. Expand
Sand patties provide evidence for the presence of Deepwater Horizon oil on the beaches of the West Florida Shelf.
TLDR
PAH analysis provided support for the theory that DWH oil made its way onto beaches of the West Florida Shelf. Expand
Challenging Oil Bioremediation at Deep-Sea Hydrostatic Pressure
TLDR
This mini-review aims at highlighting the missing information in the field, proposing a holistic approach where in situ and ex situ studies are integrated to reveal the principal mechanisms accounting for deep-sea oil bioremediation. Expand
Environmental effects of the Deepwater Horizon oil spill: A review.
TLDR
Research demonstrates that oiling caused a wide range of biological effects, although worst-case impact scenarios did not materialize, and certain impacts are still understudied, such as effects on seagrass communities. Expand
Mercury bioaccumulation in tilefish from the northeastern Gulf of Mexico 2 years after the Deepwater Horizon oil spill: Insights from Hg, C, N and S stable isotopes.
TLDR
Comparing Hg isotopic composition in liver and muscle of fish indicates specific metabolic response in fish having accumulated high levels of MMHg, and suggests that suspended particles from the MR reduces Hg bioavailability at the base of the GoM food chains. Expand
Population genomics of Fundulus grandis exposed to oil from Deepwater Horizon
TLDR
The minimal impacts detected to populations along the Mississippi coast likely reflects the complexity of the northern Gulf of Mexico and DWH oil spill, and it is recognized that the patchiness of oil exposure and low genome coverage of the data limit the ability to conclude there were no DWH effects on these populations. Expand
Hydrocarbon contamination affects deep-sea benthic oxygen uptake and microbial community composition
Accidental oil well blowouts have the potential to introduce large quantities of hydrocarbons into the deep sea and disperse toxic contaminants to midwater and seafloor areas over ocean-basin scales.… Expand
Distribution of petrogenic polycyclic aromatic hydrocarbons (PAHs) in seafood following Deepwater Horizon oil spill.
TLDR
Polycyclic aromatic hydrocarbons (PAHs), major toxic constituents of crude oil, in the seafood collected from gulf coast during December 2011-February 2014 are far below FDA levels of concern for human consumption. Expand
eDNA-based bioassessment of coastal sediments impacted by an oil spill.
TLDR
Environmental DNA metabarcoding was applied to characterize changes in the structure of micro- and macro-biota communities of surface sediments over a 7-year period since the occurrence of Hebei Spirit oil spill to provide a powerful tool for assessing effects of anthropogenic pollution. Expand

Effects of COREXIT ® EC9500A on bacteria from a beach oiled by the Deepwater Horizon spill
TLDR
The data suggest that hydro - carbon-degrading bacteria are inhibited by chemical dispersants, and that the use of dispersants has the potential to diminish the capacity of the environment to bioremediate spills. Expand
Rapid microbial respiration of oil from the Deepwater Horizon spill in offshore surface waters of the Gulf of Mexico
The Deepwater Horizon oil spill was one of the largest oil spills in history, and the fate of this oil within the Gulf of Mexico ecosystem remains to be fully understood. The goal of this… Expand
Hydrocarbon-Degrading Bacteria and the Bacterial Community Response in Gulf of Mexico Beach Sands Impacted by the Deepwater Horizon Oil Spill
TLDR
It is concluded that oil contamination from the DH spill had a profound impact on the abundance and community composition of indigenous bacteria in Gulf beach sands, and evidence points to members of the Gammaproteobacteria (Alcanivorax, Marinobacter) and AlphaproteOBacteria (Rhodobacteraceae) as key players in oil degradation there. Expand
Deep-Sea Oil Plume Enriches Indigenous Oil-Degrading Bacteria
TLDR
It is reported that the dispersed hydrocarbon plume stimulated deep-sea indigenous γ-Proteobacteria that are closely related to known petroleum degraders, and the potential exists for intrinsic bioremediation of the oil plume in the deep-water column without substantial oxygen drawdown. Expand
Propane Respiration Jump-Starts Microbial Response to a Deep Oil Spill
TLDR
Investigation of deep underwater hydrocarbon plumes in the Gulf of Mexico found propane and ethane trapped in the deep water may promote rapid hydrocarbon respiration by low-diversity bacterial blooms, priming bacterial populations for degradation of other hydrocarbons in the aging plume. Expand
Responses of microbial community from northern Gulf of Mexico sandy sediments following exposure to Deepwater Horizon crude oil.
TLDR
Findings indicate that hydrocarbon degradation by extant microbial populations in the northern Gulf of Mexico sandy beach environments can be stimulated and enhanced by inorganic nutrient addition. Expand

Analysis of eight oil spill dispersants using rapid, in vitro tests for endocrine and other biological activity.
TLDR
A series of in vitro high-throughput assays on eight commercial dispersants focused on the estrogen and androgen receptors (ER and AR), but also included a larger battery of assays probing other biological pathways. Expand
Embryotoxicity of mixtures of weathered crude oil collected from the Gulf of Mexico and Corexit 9500 in mallard ducks (Anas platyrhynchos).
TLDR
Results indicated that decreasing ratios of dispersant relative to weathered crude oil decreased toxicity to mallard embryos, and toxicity increased when the oil to dispersant ratio was 50:1, but decreased with the mixture that contained more dispersant (10:1). Expand
