Port Valdez Sediment Coring Program - 2004 Monitoring Report

TDI-Brooks as a subcontractor to Kinnetic Laboratories Inc. (KLI) completed a project for the Prince William Sound (PWS) Regional Citizens' Advisory Council (RCAC). The RCAC is interested in the long-term input of hydrocarbons from the operations of the Alyeska Marine Terminal (AMT) and other anthropogenic sources of hydrocarbon input into Port Valdez and surrounding waters.

Oil transportation and associated activities have had notable effects on the marine environment in the study area of Port Valdez and Prince William Sound. To better define the extent of anthropogenic and other historic inputs into Port Valdez and surrounding waters, a sediment coring program was contracted by RCAC in 2004. The basic objective of this program was to collect sediment cores and determine sediment rates and hydrocarbon concentrations/distributions at selected locations in Port Valdez.

As prime contractor, KLI used the MV AUKLET to collect the sampling effort. TDI-Brooks and Florida Institute of Technology (FIT) conducted the hydrocarbon chemistry and radioisotope core dating components, respectively. The results of the study were present in August 2005 in a 2004 Monitoring Report for the project.
