One of the larger C-IMAGE tasks, this task studies the impacts and recovery of oiled sediments, the trajectory and fate of oil spills, chemical and biological processes effecting distribution and toxicity, and the influence of dispersants on these processes. Researchers from the sedimentary deposition, degradation and ecotoxicology task have collected seafloor sediment samples in Mexican, American, and Cuban waters around the Gulf of Mexico to study the Gulf-wide processes.

Studying the 2010 Deepwater Horizon and 1979 Ixtoc I spills gives our studies a diverse and robust set of sediments to study:

  • Radio isotopes
  • Benthic meio- and macrofauna
  • Marine oiled snow
  • Microbial degradation
  • Trace elements in sediment pore water, and
  • Geochemistry

The future goals for the sedimentary deposition group includes:

    • Complete analysis of sediment samples collected in 2017 (Δ14C, δ13C, forams, macrofauna, 234Th)

Assess ecosystem impacts of MOSSFA using Deepwater Horizon and Ixtoc I findings

  • Identify components for MOS formation and distribution, and
  • Develop a dispersion model to simulate MOSSFA production
