Three-Dimensional Modeling of Hydrodynamics and Salinity in the San Francisco Estuary: An Evaluation of Model Accuracy, X2, and the Low–Salinity Zone

open access: yesSan Francisco Estuary and Watershed Science, 2015
doi: http://dx.doi.org/10.15447/sfews.2015v13iss1art2The three-dimensional UnTRIM San Francisco Bay–Delta model was applied to simulate tidal hydrodynamics and salinity in the San Francisco Estuary (estuary) using an unstructured grid.

Distribution and Invasion Potential of Limonium ramosissimum subsp. provinciale in San Francisco Estuary Salt Marshes

open access: yesSan Francisco Estuary and Watershed Science, 2014
Non-native sea lavenders (Limonium spp.) are invasive in salt marshes of southern California and were first documented in the San Francisco Estuary (the estuary) in 2007. In this study, we mapped distributions of L. ramosissimum subsp. provinciale (LIRA)

Sediment Supply and Marsh Development in the San Francisco Estuary

open access: yes, 2006
This project sought to gain a better understanding of the long-term feasibility of restoring tidal marshes in San Pablo Bay in the San Francisco Estuary, by identifying sources of inorganic sediments that maintain the marshes’ elevations relative to sea level.

Biological effects of anthropogenic contaminants in the San Francisco Estuary

Environmental Research, 2007
Concentrations of many anthropogenic contaminants in the San Francisco Estuary exist at levels that have been associated with biological effects elsewhere, so there is a potential for them to cause biological effects in the Estuary. The purpose of this paper is to summarize information about biological effects on the Estuary's plankton, benthos, fish ...

Decadal mercury trends in San Francisco Estuary sediments

Environmental Research, 2007
Monitoring sediment quality and total mercury concentrations over the period 1993-2001 at 26 stations in San Francisco Estuary has shown the seasonal cycling of mercury sediment concentrations, as well as a significant (P < 0.05) decrease in those concentrations at eight stations across the estuary.

Mercury speciation in the San Francisco Bay estuary

Marine Chemistry, 2003
In order to understand the biogeochemistry of mercury in the San Francisco Bay estuary, California, we undertook a 2-year study of sediments and surface waters to investigate sources of mercury to the estuary and the processes that control its distribution. Over several seasons, unfiltered and filtered (

Mercury in the San Francisco Estuary

2008
This review presents some of the published and other important literature on mercury contamination in San Francisco Estuary. Studies on human consumption of contaminated sportfish and on detecting ecological impacts of this contamination in wetland areas validate concerns regarding mercury's toxicity in this system.

Patterns and trends in sediment toxicity in the San Francisco Estuary

Environmental Research, 2007
Widespread sediment toxicity has been documented throughout the San Francisco Estuary since the mid-1980s. Studies conducted in the early 1990s as part of the Bay Protection and Toxic Cleanup Program (BPTCP), and more recently as part of the Regional Monitoring Program (RMP) have continued to find sediment toxicity in the Estuary.

Surveillance for previously unmonitored organic contaminants in the San Francisco Estuary

Marine Pollution Bulletin, 2003
The San Francisco Estuary Regional Monitoring Program initiated surveillance monitoring to identify previously unmonitored synthetic organic contaminants in the San Francisco Estuary. Organic extracts of water samples were analyzed using gas chromatography-mass spectrometry in full scan mode. The major contaminant classes identified in the samples were
