D. H. Schoellhamer L.G. Bergfeld 2003 <p>Salinity and temperature are crucial state variables affecting estuarine habitat an d, thus, are measured by various San Francisco Estuary programs. This article presents a comparison of salinity and temperature data collected at seven continuo us monitoring stations throughout San Francisco Bay (Figure 1) with data collected monthly by the US Geological Survey (USGS) research vessel ( RV ) Polaris . The data comparison was done to determine if the continuous monitoring stations, which mostly are located near shore and always on structures in the water, are representative of water conditions in the main channel of the estuary where the RV Polaris collects measurements.</p> application/pdf en Interagency Ecological Program Comparison of salinity and temperature at continuous monitoring stations and nearby monthly measurement sites in San Francisco Bay article
