A Preliminary Report to the U.S. Coast Guard

Characterization of Sediments from the Gulf of Mexico and Atlantic Shorelines, Texas to Florida

By John T. Lisle and Norris N. Comer

Thumbnail of report cover


In response to the Deepwater Horizon oil spill, sediment samples that were projected to have a high probability of being impacted by the oil were collected from shoreline zones of Texas, Louisiana, Mississippi, Alabama, and Florida. Sixty-one sites were sampled and analyzed for hydraulic conductivity, porosity, and grain-size distribution. The objective of this effort was to provide a set of baseline data on sediment characteristics known to directly influence (1) the penetration of oil into coastal sediments and (2) the efficacy of chemical and (or) bioremediation.
