Regional Evaluation of Non-indigenous Marine Species in Prince William Sound

The report describes a survey conducted in 2023, looking for non-indigenous species (NIS) in the waters of Prince William Sound.

This image is a map of Prince William Sound with 11 locations marked where the researchers conducted monitoring.
Researchers set up sampling stations in 11 locations around the region.

Three introduced species of concern were detected in this study. Two of the three have not been detected in Prince William Sound in previous studies. This brings the total number of benthic marine invertebrate NIS in the Sound to seven.

NIS can be introduced from ballast water or on hulls of tankers visiting the Valdez Marine Terminal. The risk is considered high. The Council has supported monitoring and detection projects for decades.
