Surface and Subsurface Application of Chemical Dispersants and Associated Ecosystem Impacts
<p>Chemical dispersants are applied to spilled oil in marine environments when other, less controversial, methods are not adequate for the incident. They are considered to be a response method as opposed to a direct cleanup method, with the intended goals of reducing risk of exposure to sensitive …

Laboratory studies of the biodegradation of chemically dispersed oil: effect of droplet size and nutrient amendment
… effects on the shorelines, and for this reason, chemical dispersants are commonly used to disperse the oil slick in the water column, preventing it from reaching the shorelines. However, the long term fate of dispersed oil depends on its biodegradation by indigenous microorganisms, which in turn …

Deepwater Horizon Impacts on the Diet, Growth, and Condition of Larval Spanish Mackerel (<i>Scomberomerus maculatus</i>)
… food web caused by the release of oil and chemical dispersants during the DWHOS event. Using samples from a long-term ichthyoplankton survey off the coast of Alabama, I sought to resolve the effects of the DWHOS on larval fishes. I compared the condition, growth, and diet of larval Spanish …

A bioengineered approach for sustainable crude oil pollution treatment via entrapment, dispersal and removal using Nano-CarboScavenger
… are either inefficient or involve highly toxic chemical dispersants. In this work we adopt a commercially-amenable nanotechnology based approach to design tunable, biodegradable particles for efficient and safe petroleum remediation. Exhaustively characterized 100 nm sized hybrid dual-shelled …

Intrusion dynamics of particles or droplets released continuously to the deep ocean
… oil droplets with and without treatment using chemical dispersants is addressed experimentally and analytically. Next, we characterize the dependence of plume trapping behavior with crossflow velocity, bridging a gap in the current plume parametrization scheme. We also present a novel …

Intrusion dynamics of small oil droplets from a deep ocean blowout
… Horizon spill conditions, with and without chemical dispersants.

Effects of droplet size on intrusion of sub-surface oil spills
… when analyzing their radial plume spread. Chemical dispersants produce small oil droplets and the current experiments provide references on the minimum diameter needed for efficient particle spread (Type la* plume). By knowing the following parameters for a scenario - 1) initial buoyancy …
