FREEPORT, Texas – The first of four new “Sentinels of the Coast” data collection stations is now in the water at Surfside.
Contractors began installing the sentinel on Oct. 15 and crews continued work through Saturday, maneuvering the giant steel pile into its proper position. The top was placed Saturday morning.
“This sentinel and the three additional systems that will be installed over the next several weeks will be added to list of 29 existing Texas Coastal Ocean Observation Network (TCOON) stations that give Texas the most extensive coastal monitoring network in the country,” said James Rizzo, Assistant Director of Operations for the Conrad Blucher Institute of Surveying and Science at Texas A&M University-Corpus Christi. “The TCOON will have a monitoring station at all six major inlets on the Texas Coast that will providing near real-time weather and water level data, a network that is the envy of coastal states in the country.”
These sentinels, along with the other TCOON stations, provide continuous water level and weather data that helps coastal communities better prepare for severe weather by providing accurate data that increase accuracy of forecasts that can save lives and property.
The Sentinel of the Coast structures consist of a single pile --- 140 feet tall and nearly 50 inches around --- driven into the seafloor with an instrumentation platform installed 32 feet above Mean Sea Level. Each structure is rated to withstand the forces of a Category 4 Hurricane with an 18 foot storm surge, 10 foot high wave, and winds 100 plus miles per hour. The high-tech instrumentation will be installed to the National Oceanic and Atmospheric Administration standards.
After the installation at Freeport, contractors will move to the installation at the Matagorda Ship Channel near Port O’Connor, then Port Aransas, and finally, South Padre Island, all critical locations along the coast.
The CBI oversees design, construction, and installation of each structure. Once the sentinels are erected, CBI will install equipment and initiate operation and data collection from these new monitoring stations that will be incorporated into the TCOON.

The new stations are expected to be online by June 2016.
“These new stations will allow us to monitor conditions before, during, and after a hurricane has made landfall,” said Rizzo. “The data will be used by local National Weather Service and National Hurricane Center personnel for forecasting models. The data will be an invaluable resource to local, state, and other federal agencies during storm events.”
The project is possible through a $2 million grant awarded to CBI from the Coastal Impact Assistance Program administered by the U.S. Department of Interior through the U.S. Fish and Wildlife Service, managed locally by the Texas General Land Office.
Rizzo says that after the storm, the information will be used by numerous agencies as they assess damage along the Texas coast and to the adjacent waterways. The stations will provide accurate, real-time water level, wind speed, direction, and gust information, barometric pressure, and temperatures.
“This data will assist scientists and researchers in improving models related to storm conditions and their effects on the Texas Coast,” said Rizzo. “The accuracy of these forecasts is what saves lives.”
CBI completed the installation of two identical data collection stations in 2011, which are located at Texas Point on the Sabine River and at the Galveston Entrance Channel North Jetty.
Since 1989, the CBI has provided real-time meteorological information essential for predicting and measuring water levels throughout the TCOON. In all, there are 29 monitoring stations along the Gulf Coast.
