Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.0001. Longitudes are given to the nearest 0.0001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.
The flattening of the ellipsoid used is 1/298.257.
The data files contain the following for each date: date of collection; temperature in degrees Celsius; specific conductance in microsiemens per centimeter; salinity in parts per thousand; and latitude and longitude in decimal degrees
Project personnel include Shane Ploos, Lars Soderqvist, Craig Thompson, and Barclay Shoemaker

The Water Resources Development Act (WRDA) of 2000 authorized the Comprehensive Everglades Restoration Plan (CERP) as a framework for modifications and operational changes to the Central and Southern Florida Project needed to restore the south Florida ecosystem. Provisions within WRDA 2000 provide for specific authorization for an adaptive assessment and monitoring program. A Monitoring and Assessment Plan (MAP) has been developed as the primary tool to assess the system-wide performance of the CERP by the REstoration, COordination and VERification (RECOVER) program. The MAP presents the monitoring and supporting enhancement of scientific information and technology needed to measure the responses of the South Florida ecosystem.The MAP also presents the system-wide performance measures representative of the natural and human systems found in South Florida that will be evaluated to help determine the success of CERP. These system-wide performance measures address the responses of the South Florida ecosystem that the CERP is explicitly designed to improve, correct, or otherwise directly affect. A separate Performance Measure Documentation Report being prepared by RECOVER provides the scientific, technical, and legal basis for the performance measures. This project is intended to support the Greater Everglades (GE) Wetlands module of the MAP and is directly linked to the monitoring or supporting enhancement component
In 2003, CERP MAP funding through the South Florida Water Management District established 10 monitoring stations as part of the Coastal Gradients Network. The purpose of this MAP project with the USACE is to continue operation of these 10 stations for the MAP activities.
Salinity surveys will be performed using boat-mounted systems to collect information along the southwestern coast of ENP, northeastern coast of Florida Bay, and Manatee Bay/Barnes Sound. The information will include salinity and temperature data and geographic location in latitude and longitude for every data point. Four quarterly and two event-driven surveys will be completed on a yearly basis for a maximum of six per year. The salinity survey is performed on the same day across the study area and usually requires the use of 4 boats and 8 crew members to complete. The surveys will include these river/creek systems: Lostmans River to upstream Lostmans River; Broad River to upstream Broad River; Shark River/Harney River to Bottle Creek; North River to upstream North River; McCormick Creek to Seven Palm Lake; Taylor River mouth to upstream Taylor River; Trout Creek to Joe Bay/Snag Bay; and Barnes Sound to Manatee Bay/Card Sound Canal.
Salinity surveys are performed using boat-mounted flow-through systems equipped with a YSI water quality monitor for collection of temperature and salinity. Position is determined using a GPS unit which interfaces with the YSI water quality monitor. Data collection occurs every 5 seconds and is stored in the YSI 650 data acquisition system. The accuracy of all instrumentation is verified in the USGS Ft. Lauderdale laboratory or in the field before and after the salinity survey. The temperature probe is verified using a digital NIST thermometer in the Ft. Lauderdale lab. Data collected from the four boats is combined in a spreadsheet and analyzed for erroneous data such as spikes and 0.0 values. Salinity data is then imported into a GIS package for map creation. Raw data and spatial maps will be posted on SOFIA or published in the final USGS Data Series Report to be published in 2010.

The geographic coordinates were collected with a Garmon 76C handheld unit
Salinity maps are available for Water Year 2004 (December 2003, March, June, and August, 2004); Water Year 2005 (October and December 2004 and March, May, and July 2005); and Water Year 2006 (November 2005, and April and June 2006)
Salinity and temperature were measured along the same transects for each survey. These transects were measured using four separate boats over the span of one day and the data was then combined to create a salinity map of the coastline along Everglades National Park.
Are there legal restrictions on access or use of the data?
