High-Pressure Biodegradation

High-Pressure Biodegradation – Dr. Andreas Liese – Technical University of Hamburg The degradation of oil, methane, and changes in bacterial communities during biodegradation are tested in pressurized vessels. Rhodococcus PC20 from Gulf of Mexico sediments is used to measure differences…

OneGulf-Fisheries Health

Gulfwide Fisheries Health – Dr. Steven Murawski – University of South Florida Continuous bottom long line surveys in Gulf waters have established a new pre-spill baseline of oil spills. Studies of fish health include:Polycyclic Aromatic Hydrocarbon (PAH) levels in fish…

Ecosystem Modeling

Ecosystem Modeling – Dr. Cam Ainsworth – University of South Florida-College of Marine Science To synthesize the efforts of the other five tasks, ecosystem modeles have been developed for the Deepwater Horizon recovery (Atlantis) and Ixtoc I recovery (Campechec Bay…

Marine Snow Experiments

Marine Snow Experiments – Dr. Albertinka Murk – Wageningen University Mesocosm experiments create marine oiled snow and assess the impacts on benthic communities and oil biodegradation in aquarium settings.

Microbial Communities

Microbial Communities – Dr. Joel Kostka – Georgia Institute of Technology The impact of microbial degradation is studied through several projects within task 3: the affect of dispersants on microbial communities at high-pressure and oceanographic controls, anaerobic hydrocarbon degradation, and…

Benthic Meiofauna & Macrofauna

Benthic Meiofauna & Macrofauna – Dr. Paul Montagna – Harte Research Institute/Texas A&M-Corpus Christi Meio- and macrofaunal communities in the Gulf provide diverse ecosystem services to the benthic environment. Animals like Copepods and Nematodes are the base of the food…

Trace Elements in Sediments

Trace Elements in Sediments – Dr. David Hastings – Eckerd College Processing sediment cores at 2 mm resolution and analyzing them through ICP-MS for trace elements (Mn, Fe, Re, U, Mo, Cd, Cu, V, and Cr). Pore water from Gulf…

Partitioning Behavior of Crude

Partitioning Behavior of Crude – Dr. Thomas Oldenburg – University of Calgary The dissolution of oil fragments and methane at varying depth and temperature, with or without dispersants is tested in the Calgary partitioning device. The solubility of BTEX (benzene-toluene-ethylbenzene-xylene),…

Deepwater Horizon Hindcast Model

Coupled Near- and Far-field Components - Dr. Scott Socolofsky & Dr. Claire Paris - Texas A&M University & University of Miami Compiling surface distributions, sediment contamination, droplet size distribution, and ocean circulation creates a 4-dimensional visualization of the Deepwater Horizon…
