Summary

To address the data and information gap for characterizing coastal drought, a coastal salinity index (CSI) was developed using salinity data (Conrads 2016; Conrads and Darby, 2017). The CSI uses an approach similar to the Standardized Precipitation Index (SPI), a readily available drought index that is widely used for monitoring meteorological droughts (McKee and others, 1993). The CSI substitutes total monthly precipitation with monthly mean salinity data to determine the probability of recording a given salinity value in a particular month. The initial investigation demonstrated that the index could be used to delineate short- and long-term drought (saline) and wet (high freshwater inflow) conditions; however, to advance the use [...]

Purpose

The data were collected in the field under the (1) U.S. Geological Survey (USGS), (2) National Estuarine Research Reserve System (NERRS), (3) Georgia Coastal Ecosystems Long Term Ecological Research (LTER), and (4) Lower Colorado River Authority (LCRA) stream gaging programs to meet the needs of the collection agency and any cooperating agency for each gage. To advance the use of the Coastal Salinity Index (CSI) as a drought monitoring tool, CSI calculations need to be made available to the scientific community.
