This lesson is designed to complement Project Oceanology’s “Introduction to Oceanography” boat trip, although it can also be used as a stand-alone lesson.  Students examine Project Oceanology’s historical dataset of organisms captured and water quality characteristics, and make graphs showing how the biological and physical nature of Long Island Sound has changed (or not) over time.  The activity can take place in the Project Oceanology computer lab immediately before or after a trip, or in the classroom after students have returned home.
