Local residents can check tidal elevations here minute by minute
at their computer as Hurricane Katrina advances, thanks to a new
National Oceanic and Atmospheric Administration tide station.
The new water level station at the end of the
Gulf Coast Research Laboratory pier is providing updates online
at tidesonline.nos.noaa.gov. The site includes charts updated every
15 minutes and data recorded and reported in real-time.
The station dedicated in May helps measure
storm surge and land subsidence. It is the second for Mississippi
and the first on the coast to be co-located with a GPS-based Continuously
Operating Reference Station (CORS). A CORS provides highly accurate
positioning information to the coastal surveying, engineering and
The water level station is part of a height
modernization initiative that the National Oceanic and Atmospheric
Administration established at The University of Southern Mississippi
Gulf Coast Geospatial Center at GCRL. The new Southern Miss program
is installing a CORS network in coastal Mississippi along with co-located
water level stations at selected CORS sites.
A one-year NOAA grant of $532,256 this summer
is continuing the program that is designed to provide the resources
for Mississippi to gather needed data on land elevations and to
relate those measurements to the changes in sea levels in the Gulf
of Mexico. David S. Mooneyhan, associate director of the center
at the GCRL, is principal investigator of the program.
