Nahant Methods

          Using a .25 meter squared quadrate mussels were found in the intertidal at two different locations canoe beach, a shelters location, and east point a more exposed beach. When mussels were found the quadrate was positioned so the majority of the mussels were in the center. The number of mussels was counted. The present barnacle cover was also determined. Each site had at least 20 quadrate records.

            Mussels were plotted against the percent of barnacle cover. A regression was  preformed to see if there was a significant trend of increasing number of mussels with increase barnacle percent cover.
