ME34B:
Processes Impacting the Distribution and Fate of Oil in the Marine Environment II Posters


Session ID#: 28069

Session Description:
Oil occurs in the marine environment both naturally and through human activity. Research results arising from the 2010 Deepwater Horizon oil spill and the recent re-evaluation of the 1979 Ixtoc-I oil spill in the Gulf of Mexico, as well as from work on natural seep sites, have quantified processes that control the distribution and fate of oil within food webs and the environment. Specifically, marine snow formation, incorporation of oil, and subsequent gravitational settling to the seafloor is now recognized as a significant pathway for the distribution and fate of oil. Riverine processes and ocean circulation affect oil particle coagulation and transport. Dispersant application impacts oil droplet size, but also may have lethal and sublethal effects on the lower trophic food web. Microbes transform, repackage, and distribute oil throughout the water column and on the seafloor. Oil accumulation on the seafloor impacts benthic animals and fishes, where rates of recovery may be slow. Consumption and/or bioaccumulation of oil by benthic and upper trophic level animals, such as fishes and marine mammals, also affect both ecosystem function and the distribution of oil within the food web. We welcome observational, experimental, and modeling contributions that examine and help quantify these processes.
