  • Chemical data quantify Deepwater Horizon hydrocarbon flow rate and environmental distribution 

    Ryerson, Thomas B.; Camilli, Richard; Kessler, John D.; Kujawinski, Elizabeth B.; Reddy, Christopher M.; Valentine, David L.; Atlas, Elliot; Blake, Donald R.; de Gouw, Joost; Meinardi, Simone; Parrish, David D.; Peischl, Jeff; Seewald, Jeffrey S.; Warneke, Carsten (2011-11-11)
    Detailed airborne, surface, and subsurface chemical measurements, primarily obtained in May and June 2010, are used to quantify initial hydrocarbon compositions along different transport pathways – in deep subsurface plumes, ...
  • Climatically driven emissions of hydrocarbons from marine sediments during deglaciation 

    Hill, T. M.; Kennett, J. P.; Valentine, David L.; Yang, Z.; Reddy, Christopher M.; Nelson, Robert K.; Behl, R. J.; Robert, C.; Beaufort, L. (2006-07-31)
    Marine hydrocarbon seepage emits oil and gas, including methane (~30 Tg CH4/year), to the ocean and atmosphere. Sediments from the California margin contain preserved tar, primarily formed via hydrocarbon weathering at ...
  • Dissolved methane distributions and air-sea flux in the plume of a massive seep field, Coal Oil Point, California 

    Mau, Susan; Valentine, David L.; Clark, Jordan F.; Reed, Justin; Camilli, Richard; Washburn, Libe (American Geophysical Union, 2007-11-24)
    Large quantities of natural gas are emitted from the seafloor into the stratified coastal ocean near Coal Oil Point, Santa Barbara Channel, California. Methane was quantified in the down current surface water at 79 stations ...
  • Fate of dispersants associated with the Deepwater Horizon oil spill 

    Kujawinski, Elizabeth B.; Kido Soule, Melissa C.; Valentine, David L.; Boysen, Angela K.; Longnecker, Krista; Redmond, Molly C. (2011-01-05)
    Response actions to the Deepwater Horizon oil spill included the injection of ~771,000 gallons (2,900,000 L) of chemical dispersant into the flow of oil near the seafloor. Prior to this incident, no deepwater applications ...
