California in Receives Asstistance to Assess the Impact of an Oil Spill in San Francisco Bay to Aid in Recovery and Remediation Efforts
As a result of the Cosco Busan oil spill in November 2007, scientists from NOAA’s National Centers for Coastal Ocean Science (NCCOS) partnered with the Office of Response and Restoration (OR&R) and the California Water Resources Control Board to collect and analyze mussel tissue samples from five affected Bay locations. The pre-spill range of total polycyclic aromatic hydrocarbon (PAH) concentrations was 7-20 parts per million, while post-spill results were three times higher than previously reported, and nearly 10 times higher than what was found at the site in January 2007. NCCOS’s Mussel Watch has been monitoring contaminants in San Francisco Bay since 1986, including a wide range of petroleum products. NCCOS will continue to work closely with OR&R over the coming months to assess impacts of this recent spill. Significance: Data from programs like the Mussel Watch are useful in showing the negative impacts of events, such as oil spills and industrial accidents, on the environment by showing what the levels of contaminants were before and after the event.
