Scientists used 3D regional ocean model simulations and sediment trap data to investigate how large (mesoscale) and small (submesoscale) circulations affect the transport of sinking particles, or marine snow, in the northern Gulf of Mexico. Small-scale convergence and divergence processes (a few kilometers) and cross-shore transport of riverine inputs induced by mesoscale eddies significantly influenced the speed and trajectory of sinking particles in offshore waters.

Researchers developed an algorithm that accounts for different wind speeds, oil types, natural dispersion processes (breaking waves), and chemical dispersant application to analyze oil slick evolution scenarios. The model results indicate how the oil slick will become thinner and dissipate over time as a result of dispersion.

Scientists conducting oil spill research participated in the 2013 Marine Oil Snow Sedimentation and Flocculent Accumulation (MOSSFA) workshop. The researchers discussed the formation and fate of oil-associated marine snow and its ecological impacts on deep-sea environments and made recommendations for future marine oil snow research.

Authorities closed large portions of the Gulf of Mexico to commercial and recreational fishing following the Deepwater Horizon oil spill to contain and mitigate oil contamination of fish and seafood products. The fishing closures may have caused many fishers to search for alternative income solutions, such as relocating or chartering their vessels for the cleanup process.
