Sediment samples were collected during the fall, 2010, along the U.S. continental shelf in the Gulf of Mexico.  Bottom samples were collected using a Shipek grab sampler.  Dried samples were analyzed for nickel using ICP.  Nickel is a trace metal component of the crude oil released from the BP Deepwater Horizon oil spill in April 2010.  The release of this crude oil could provide a new source of trace metals to the sediments forming the continental shelf.  Carbonate sediments collected off of the Gulf coast of Florida had a mean nickel concentration of 5.31 + 3.81 micrograms of nickel per gram of dry sediment.  Deltaic sediments collected off of the Louisiana coast had a mean nickel concentration of 9.09 + 3.58 micrograms /g.
