Frequently-anticipated questions:


What does this data set describe?

Title: TIME Data
Abstract:
The TIME Database has been discontinued and links are provided to individual agencies - Everglades National Park (ENP/MMN), South Florida Water Management District (SFWMD), National Oceanic and Atmospheric Administration (NOAA), and the U.S. Geological Survey (USGS) - to obtain the data previously stored in the database.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      Indirect_Spatial_Reference: Florida Everglades stations

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.01. Longitudes are given to the nearest 0.01. Latitude and longitude values are specified in Degrees, minutes, and decimal seconds.

      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.

Why was the data set created?

A critical objective of the south Florida ecosystem restoration effort is to preserve ecological conditions that are consistent with habitat requirements. The duration, timing, and extent of wetland inundation in the southern Everglades have been greatly distorted as evidenced by shifts in biologic and vegetative species. Both natural and regulatory factors contribute to influence of hydroperiods making their precise evaluation and management difficult. This complexity is particularly problematic in the transition zone between the Everglades wetlands and coastal embayments encompassing the mangrove ecotone where freshwater inflow effects on salinities must also be considered. In order to correctly and sufficiently investigate flow effects on both hydroperiods and embayment salinities neither hydrologic processes affecting flows in the wetlands nor the dynamic effects of external forces such as tides and winds can be ignored. This project entails translation of findings from the Southern Inland and Coastal Systems (SICS) project and extension of the model westward to resolve boundary limitations and to enable concurrent analysis of wetland and tidal response throughout the entire saltwater-freshwater interface zone along the Gulf coast and Florida Bay. Extension of the SICS model westward will require the addition of continuous monitoring stations to supplement data from coastal creek stations and control structures needed to provide boundary conditions as well as the synoptic measurement of flows and water levels in the wetlands for use in model calibration and verification.
