Prince William's Oily Mess: A Tale of Recovery

Working with Real Data

   

Graphing Changes in Marine Life Abundance

Welcome to Working with Real Data! In this hands-on activity, students work with real data collected by scientists at NOAA’s National Ocean Service, who are studying the ecological recovery of Prince William Sound following the Exxon Valdez oil spill. From photos of sampling quadrats at Mearns Rock, an oiled shoreline boulder, students record the abundance of marine intertidal organisms, graph the data and interpret their results.
