System Wide Monitoring Program (SWMP)

Weather station at Rush Ranch.

Long-term monitoring is essential to understanding ecosystems and placing shorter-term research into context. In an estuary, water-quality and weather data are especially important. The National Estuarine Research Reserve System conducts high-quality, standardized monitoring at each of the 28 Reserves and provides data online in an easily accessible format at – we recommend and Data Export System for graphing and downloading data and the Real Time Data for a quick check on current conditions.

Water Quality Parameters measured every 15 minutes: water level, temperature, salinity, dissolved oxygen, pH, and turbidity

Water Quality Parameters measured monthly: ammonium, nitrate, nitrite, ortho-phosphate, chlorophyll a

Water Quality Station Locations:
Gallinas Creek, San Rafael (station code: SFBGCWQ)
China Camp, on the historic pier at the Village, San Rafael (station code: SFBCCWQ)
First Mallard, Rush Ranch, Suisun Marsh (station code: SFBFMWQ)
Second Mallard, Rush Ranch, Suisun Marsh (station code: SFBSMWQ)

Meteorological Parameters Measured: Air temperature, barometric pressure, wind speed, wind direction, total PAR, precipitation, and relative humidity

Meterological Station is located on the edge of the marsh at Rush Ranch, near Suisun City (station code: SFBRRMET)

San Francisco Bay NERR also conducts long-term monitoring of emergent vegetation at China Camp, monthly oyster recruitment on the Marin County shoreline, and annual bay-wide oyster population surveys. This data is not currently available online, contact Research Coordinator for more information.
