Denitrifier abundance and activity across the San Francisco Bay estuary
Environmental Microbiology Reports, 2010Summary Over 50% of external dissolved inorganic nitrogen inputs to estuaries are removed by denitrification – the microbial conversion of nitrate to nitrogen gas under anaerobic conditions. In this study, denitrifier abundance, potential rates and community structure were examined in sediments from the San ...

Benthic macrofaunal assemblages of the San Francisco Estuary and Delta, USA
Environmental Monitoring and Assessment, 2012The spatial and temporal distribution of macrobenthic assemblages in the San Francisco Estuary and Sacramento-San Joaquin River Delta were identified using hierarchical cluster analysis of 501 samples collected between 1994 and 2008. Five benthic assemblages were identified that were distributed primarily along the salinity gradient: (1) a polyhaline ...

Environmental activism in the San Francisco Bay Estuary
Marine Pollution Bulletin, 1991Abstract This paper presents a brief description of the San Francisco Bay Estuary and its modifications. Problems associated with habitat loss and degradation, pollutants, freshwater diversion, and dredging are described. The activities of environmental groups addressing these problems, including several examples, are noted.

Polycyclic aromatic hydrocarbons in San Francisco Estuary sediments
Marine Chemistry, 2004Abstract The objectives of this study were to examine surface sediments in the San Francisco Estuary for PAH composition over a range of spatial and temporal scales to determine distributions, trends, and possible sources. Surface sediments (top 5 cm) were collected at 26 sites from 1993 to 2001.

Spring climate and salinity in the San Francisco Bay Estuary
Water Resources Research, 1993Salinity in the San Francisco Bay Estuary almost always experiences its yearly maximum during late summer, but climate variability produces marked interannual variations. The atmospheric circulation pattern impacts the estuary primarily through variations of runoff from rainfall and snowmelt from the Sierra Nevada and, secondarily, through variations ...

Atmospheric Concentrations and Fluxes of Organic Compounds in the Northern San Francisco Estuary
Environmental Science & Technology, 2002A study was conducted to measure atmospheric concentrations of PAHs and PCBs and estimate their fluxes between air and water in the northern San Francisco Estuary. Ambient air samples were collected once every 12 days at a single sampling site in Concord, CA, from June to November 2000, using a modified high-volume air-sampling device equipped with ...

Managing freshwater inflow to the San Francisco Bay Estuary
Regulated Rivers: Research & Management, 1989The watershed of California's Central Valley drains into San Francisco Bay, the largest estuary on the Pacific Coast. The water resources of the Valley have been intensively exploited, particularly in the last 50 years, with the construction of large-scale irrigation systems.

Coastal Management, 1993
Abstract The San Francisco Estuary Project sought to “characterize”; environmental conditions in the San Francisco Bay and Sacramento‐San Joaquin Delta. This task involved systematic description and analysis of conditions, to provide the scientific basis for policy reform.
