Musculus are small mussels that settle on eelgrass blades. We sampled these in eelgrass beds in 1991, 1993, and 1995 to estimate size and density. Divers harvested above ground portions of eelgrass from each of three stations within eelgrass beds. The samples were bagged underwater and returned to the boat where eelgrass shoots and number of Musculus were counted, and (in 1991) the eelgrass was weighed to determine blotted wet weight. Lenghts of Musculs were measured in 1991 and 1993. The data here include only alga size and density data. Other data assocaited with this project can be found in additional data packages.
