NIDIS Coastal Drought Monitoring Knowledge Assessment Workshop: USGS Real-Time Salinity Drought Index

Event Date & Time

Tuesday, 2014, January 7 - 5:00am
Charleston, SC

​The 2011-12 collapse of the oyster beds in Apalachicola Bay was a federal fisheries disaster. Lowered water levels contributed to spreading fires in the Picosin Lakes National Wildlife Refuge in North Carolina in 2008, and smoke from the fires compromised air quality in the area. Blue crab landings in South Carolina have  declined in recent years.

Drought was key to all of these events, yet monitoring and predicting drought in coastal areas is a challenge, as well as assessing the impacts of drought. Indices developed for upland areas – measuring rainfall, stream flow, soil moisture, groundwater levels and snow pack – may not tell a complete story about coastal conditions.

Salinity levels can parallel episodes of drought, and measuring salinity offers another tool for drought monitoring.
The workshop introduced a new USGS coastal drought index, currently under  development at the USGS South Carolina Water Science Center. Presenters offered examples of how this coastal drought index may be used for the NIDIS Carolinas Coastal Ecosystems Drought Early Warning Pilot.
