The USGS will begin recovery of 38 storm-surge sensors, 4 wave-high sensors, 10 barometric-pressure sensors, and 4 rapid-deployment gages that were deployed prior to the storms arrival. This work will be carried out by at least 8 teams from the New York, Georgia, and North Carolina Water Science Centers. In addition, these teams will begin marking and surveying numerous high-water marks in the region to document this record flooding event.
