R Package
The CSI R package allows users to calculate the monthly Coastal Salinity Index (CSI) using monthly, daily, or interval salinity or specific conductance data for suites of gages. It supports pre-processing of data, filling of missing values, plotting, and generating of metadata. The software package is available for download from https://code.usgs.gov/water/eden/CSI.
Real-time Data
Real-time CSIs are currently available on this site and the USGS South Florida Information Access (SOFIA) Coastal Everglades Depth Estimation Network (EDEN) site. These real-time CSIs were generated for USGS National Water Information System (NWIS), National Estuarine Research Reserve System (NERRS), and Everglades National Park stations with long-term specific conductance and salinity data.
