Mearns Rock Quadrat 2004

Mearns Rock Quad 2004

Much of the quad is covered by young Fucus plants in 2004. No mussels are visible. The tiny barnacles that set in 2003 have grown, creating a white crust under the Fucus. This year, there is little or no bare rock. Note the new species of seaweed (resembling a spider) in the upper right section.
