Motivation• Key stressors during drought:
salinity and reduced freshwater availability
• Focus of the Coastal Carolinas Drought Early Warning System (DEWS)
• “Can a unique index be developed to characterize coastal drought?”

Next steps and future plans• Proposals to USGS and NOAA-NIDIS
• Expand the real-time CSI network• East coast, Gulf of Mexico
• Case studies to:• Analyze drought, salinity, and ecological linkages• Identify critical thresholds and decision points• Evaluate use for resource and drought management
