Benthic macrofauna and ancillary data for San Francisco Bay, California, March to November 1987
Benthic macrofauna and ancillary data were collected during 1987 as part of the U.S. Geological Survey Regional Effects Monitoring Program in San Francisco Bay, California. Data were collected during five cruises at 2-month intervals from March through November. Benthic macrofauna for identification of species and sediment for size analysis were sampled at eight stations. Ancillary data, which consisted of salinity, temperature, dissolved-oxygen concentrations, and suspended sediment, were collected at 12 stations. Salinity and temperature were measured at three stations that coincided with continuous water quality monitors. Abundances and geographical distributions of a newly introduced species of clam were measured. (USGS)

Physical and chemical data for northern San Francisco Bay, California, September through November, 1984
This report presents physical and chemical data for northern San Francisco Bay waters. Samples were collected during the late summer and fall of 1984 during six cruises at near-two-week intervals. Bay waters were sampled at designated (historical) stations and selected salinitis along the deep channel of northern San Francisco Bay. Measurements included temperature, salinity, turbidity, in vivo fluorescence, chlorophyll a, alkalinity, suspended particulate matter, dissolved organic carbon, and dissolved inorganic nutrients: nitrite, nitrate + nitrite, ammonium, dissolved silica, and ortho-phosphate. Numerical results are tabulated and methods are described. (USGS)
