News Release: North Carolina Storm-Tide Sensor Network Strengthened:
USGS Storm Sensor Bracket installed at Oriental, NC.
Vital coastal storm-tide information needed to help guide storm response efforts following major storms affecting North Carolina will be more accessible than ever due to a new monitoring network the U.S. Geological Survey is currently building.
Teams from the USGS South Atlantic Water Science Center are surveying more than 150 locations in North Carolina, determining their elevations and installing receiving brackets at sites that will hold a network of sophisticated sensors that can be installed days-to-hours before a storm makes landfall. Based on the forecasted storm track, a subset of brackets will be selected for sensor deployment. The network, which will include sites from North Carolina to Maine, will dramatically decrease the time it takes to provide FEMA, NOAA and other agencies information they need.
Past sensor deployments involved waiting until there was a fair degree of confidence on where the storm was most likely to make landfall, then quickly deploying numerous crews to install the sensors. Following the storm, crews returned to the sites, not just to retrieve the sensor, but also to determine the sensor’s elevation and conduct GPS surveys to determine the storm-tide elevation and flood extent. Each survey required hours, and with numerous sites to survey, it could take months before the dataset was complete.
With the new network of pre-surveyed locations with pre-installed brackets, the time required to install and retrieve the sensors and process the data will be cut to days.
