From the Abstract: “This paper presents results from a study of concentrations of total mercury (Hg) and methylmercury (MeHg) in seabed sediments near six offshore drilling sites in the Gulf of Mexico.
From the Abstract: “This paper reviews scientific information on chemical forms and fate in the marine environment of mercury associated with drilling fluid barite.
From the Abstract: “Sediment and water were collected in Camden Bay (Alaskan Beaufort Sea) during August 2008 to help establish a baseline data set in advance of proposed offshore oil and gas exploration and production.
