A Comparative Study of the Infauna of the Central Oregon Continental Shelf

摘要

There are four distinct communities on the Central Oregon shelf lying in four distinct sediment types more or less parallel to the coastline. These communities can be found in the distinct substrates of beach sand, mixed silt and sand, silt, and glauconitic sand. The fauna, when compared with the East Atlantic shelf and the shelf off Southern California, is low in number of species, number of individuals, and in biomass in spite of the high production in the surface waters over the shelf.
