Hydrologic information throughout the Everglades ecosystem is key to the development of restoration strategies and for future evaluation of restoration results. There are significant hydrologic information gaps throughout the Everglades wetlands and estuaries that need to be addressed, particularly along Florida’s southwest coast. Among these gaps are flow, water level, and salinity data. This project, in conjunction with the Everglades National Park’s (ENP) marine monitoring network, will provide water level, salinity, and flow information at key points within the mangrove zone along the southwest coast of ENP. This project will also include a wetland component designed to provide water level, salinity, and "sheetflow" velocity at selected points within the "sloughs" (flow paths) flowing into the estuaries. Hydrodynamic modelers of the Everglades, Florida Bay, southwest coast estuaries, and other adjacent marine systems can use these data to calibrate and verify models describing flow patterns throughout ENP.
The data collection network established through this project included the following types and number of stations:
1. Five estuarine-river sites were be selected to monitor stage, flow, salinity and temperature, based on TIME model needs and other ecological work being done or planned within the study area. These sites included the continuation of two previously existing stations.
2. Six additional sites were instrumented to monitor stage, salinity, and temperature in order to provide maximum spatial coverage for the TIME model, in conjunction with ENP’s marine monitoring network. These sites were located at creeks flowing into the estuaries, within the "mixing" zone, with two located near shore in the open waters of the Gulf of Mexico.
3. All water surface elevations were referenced to arbitrary local datum and do not represent NGVD-29 nor NAVD-88 elevations. Elevation control will be established to NAVD-88 in the near future.
Data collection at all flow sites included continuous (15-minute interval) measurements of water level, water velocity, salinity, and temperature, and calibration measurements of discharge (no discharge measurements at wetland sites). Data collection at water level sites included continuous (15-minute interval) measurements of water level, salinity, temperature. Most continuous data were recorded and transmitted every 4 hours by way of Geostationary Operational Environmental Satellite (GOES) into the database of the USGS Miami Subdistrict office. Stations at which transmission of data was not possible nor required were logged, retrieved, and stored into the database of the USGS Miami Subdistrict office.
Flow stations: Estuarine stream sites were instrumented with water level, salinity, temperature, velocity sensors. Velocity data was collected with acoustic Doppler instruments, calibrated with the use of an Acoustic Doppler Current Profiler (ADCP), and used in the computation of discharge. Periodic discharge measurements were done at all new sites during the first year and every four to six months thereafter for rating verification purposes. Water quality data (salinity and temperature) were collected at two depths in the water column.
Salinity stations: Salinity stations included the collection of water level, salinity, and temperature. Two of these stations were located out in the open-water boundary of the Gulf of Mexico in order to provide tidal information for the TIME model. Salinity and temperature data were collected at one or two depths, depending on site location.
Data Analysis: Discharge data was computed using established area and velocity ratings and provided to TIME model and other researchers in the best usable format for its use within the model and/or ecological research within the area.
