On October 6th, the National Integrated Drought Information System (NIDIS) and the U.S. Geological Survey (USGS) are co-hosting a national webinar to highlight the recent expansion of a coastal drought monitoring tool across the Gulf of Mexico and Eastern Seaboard. The Coastal Salinity Index (CSI) was initially developed in 2017 through the Coastal Carolinas Drought Early Warning System (DEWS) partnership to help users characterize and assess fluctuating salinity conditions in coastal areas due to events such as drought and floods. This webinar will describe the motivation for and development of the CSI, the updated CSI website which includes data from NOAA's National Estuarine Research Reserve System, and applications of the CSI to existing field investigations.
