Principal Investigator (PI): Mark Carls (NOAA/NMFS Auke Bay Laboratory)

Managing Agency: NOAA

Assisting Personnel: Pat Harris

Research Location: Prince William Sound

Restoration Category: Monitoring

Injured Resources Addressed: Mussels, Sediments

Abstract: This project will monitor mussel densities and hydrocarbon concentrations in mussels and sediments in 28 mussel beds in Prince William Sound. Twelve of these beds were restored in 1994; mussel hydrocarbon concentrations decreased significantly and replaced sediments remained clean through 1995. However, 1996 samples indicated recontamination of the replaced sediments and the potential for recontamination of mussels in some restored beds. To compare the efficacy of restoration efforts to long-term natural recovery, the project will monitor an additional 16 beds that were untreated and remained oiled when they were last sampled (1995). To complete the design, two unoiled reference beds will also be re-sampled.
