NOAA National Estuarine Research Reserve (NERR) System-wide Monitoring Program (SWMP) Meteorological, Water Quality and Nutrient/Pigment Data from 1994 to 2024

The NOAA National Estuarine Research Reserve (NERR) System-wide Monitoring Program (SWMP) collects meteorological, water quality, and nutrient/pigment data on an ongoing basis. Meteorological data provide information on atmospheric conditions that can affect water quality and biological and physical processes. Core elements currently measured at each National Estuarine Research Reserve (NERR) include air temperature, relative humidity, barometric pressure, wind speed, wind direction, rainfall, and photosynthetically active radiation (PAR). Optional parameters include total solar radiation. Each site maintains at least one meteorological station. Stations are placed at locations typical of local conditions or in areas where a specific need for weather data has been identified. Data are reported at 15 minute intervals. Prior to 2007, hourly and daily average data were also reported. Water quality observations made over long time periods can provide important feedback to scientists and to local, state, and national resource managers about actions taken to manage, protect, and restore estuaries. They also provide valuable information for evaluating the impacts of environmental change on coastal habitats and species. There are at least four water quality stations at each National Estuarine Research Reserve. Each station is designed to characterize long-term variability and short term changes in environmental conditions. Data are collected with data loggers at fifteen minute intervals and instruments are deployed continuously and year round where possible. Water quality parameters collected include: water temperature, specific conductivity, salinity, percent saturation of dissolved oxygen, dissolved oxygen concentration, pH, depth, and turbidity. Chlorophyll fluorescence is an optional parameter and pressure corrected water depth is a calculated value. There are at least four water quality stations at each National Estuarine Research Reserve. Each station is designed to characterize long-term variability and short term changes in environmental conditions. Discrete samples for nutrient and chlorophyll a concentrations are collected at each long-term monitoring station at least once monthly. More intensive (24-hours over a complete tidal cycle) sampling is conducted each month at one water quality monitoring station to better understand impacts of tide and irradiance on nutrient cycling. Nutrient parameters collected include: nitrate, nitrite, ammonium, orthophosphate, and chlorophyll a. Numerous optional parameters include dissolved organic carbon, total dissolved nitrogen, and total dissolved phosphorus. All data are provided in yearly .CSV files.
