"Table 3-7.  Abundances of benthic foraminifera in central San Francisco Bay samples collected from 1930-1981. Presence/absence given in McDonald and Diediker (1930), and percentage of total foraminifera per sample in those collected by Means (1965), Locke (1971), Wagner (1978), and Sloan (1980-1981, unpublished data).  Samples marked with an asterisk are adjusted for removal of planktic foraminiferal specimens.  No faunal counts were reported by Means for samples M-27 and M-28 or by Wagner for samples W-2675, W-2676, and W-2677. Depth of Means' samples approximated based on bottom topography map (Means, 1965) and recent U.S.G.S. bathymetric investigations (this report).  "
