Our Monitoring Study
To learn about how Prince William Sound is recovering from the Exxon Valdez oil spill, we have been conducting our monitoring study since 1990 (the year after the spill). We chose about 20 study sites around the Sound, including (1) sites that had been oiled by the spill, but not cleaned up, (2) sites that had been oiled and cleaned, and (3) sites that were not oiled.
Each year, we visit each site to measure the numbers and kinds of species of intertidal plants and animals we find there (that's what we're doing in the photo at left). We use these observations to track changes in the biological communities over time.
