POD! Water-Quality_Daily WaterTemp (1984-06) and EMP water quality
View DatasetDescription
Daily Water Temp 1984-2006 %26#226;%26#128;%26#147; average daily water temperature at three locations. EMP water quality parameters: EMP continuous %26#226;%26#128;%26#147; continuous sampling data available since 1998 EMP discrete %26#226;%26#128;%26#147; monthly sampling data available since 1975 The study area includes the Delta within its legal boundaries, Suisun Bay and Suisun Marsh, and northeastern San Pablo Bay bounded by a line between Pinole Point on the east and the Solano County line on the north shore. The EMP sampling sites range from San Pablo Bay east through the upper Estuary to the mouths of the Sacramento, Mokelumne, and San Joaquin rivers. These sites represent the main inflows and outflows of the Sacramento-San Joaquin Delta, and Suisun Bay and Suisun Marsh. They cover a salinity gradient ranging from freshwater to around 19 psu in the most western sites. Currently, 19 sites are sampled monthly throughout the year and three sites are sampled monthly during certain seasons. Continuous water quality variables: Specific conductivity, pH, dissolved oxygen, turbidity, dissolved chloride, chlorophyll fluorescence, water temperature, air temperature, wind speed and direction, solar radiation (not all parameters at all stations). Discrete water quality variables: Air and water temperature, specific conductivity , dissolved oxygen, turbidity, secchi depth, suspended solids, nitrate, nitrite, ammonia, organic nitrogen, silica, chlorophyll a, pH, water depth to 1%26#37; light level
