Equipment housings optimized for rapid deployment along the coastline to capture the tidal cycle will enable scientists to measure and analyze collected data to calculate tidal water-levels in many more locations and wave statistics like wave-height, frequency, and period to better understand the inundation from the storm and the wave forces that impacted and potentially caused damage to local structures. In New Jersey, the SWaTH Network has been added t o the existing flood-hardened, long-term, real-time tide gages, enhancing them with real-time rapid-deployment gages (RDGs), and temporary storm-tide sensors (STS). The science plan, implemented in the wake of Hurricane Sandy, included the construction of an overland Surge, Wave, and Tide Hydrodynamics (SWaTH) Network along the Northeastern Atlantic Coast to improve auxiliary sensor deployments ahead on the next major storm. These combined improvements were implemented to provide better information about local storm conditions and minimize the potential of data loss or tide gage damage during the next major coastal storm. of Environmental Protection and NJ Office of Emergency Management for secondary sensor and meteorological sensor upgrades. These upgrades were implemented in a collaborative way using federal funding for structural improvements and cooperative agreements with the NJ Dept. Meteorological sensors were also added to the NJTN to provide real-time rainfall, wind speed and wind direction data during major storms. Ten years later, the USGS NJTN has been upgraded with primary sensors elevated on raised platforms, and secondary sensors installed as backup to minimize chances of missing data during a major coastal storm event. The NJWSC also implemented a plan to upgrade the existing USGS New Jersey Tide Network (NJTN), a network of real-time tide gages and weather stations that monitor the back bays to withstand storm surge conditions from major coastal storms to better inform emergency managers and local communities about tidal conditions during a storm. A USGS science plan was developed immediately following Hurricane Sandy to improve the auxiliary sensor deployment strategy for extreme coastal storms. The New Jersey coast consists of barrier islands - narrow stretches of sand deposited parallel to the mainland coast – that were deeply eroded, overwashed, and in places breached by the storm. history and had grown into the largest hurricane ever recorded in the North Atlantic before making landfall along the coast of New Jersey in 2012. Hurricane Sandy was one of the most destructive hurricanes in U.S. ![]()
