Real-Time and Archived Tide Data Water Chemistry Data Water Quality Data Meteorological & Rain Data Biological Data
   These databases are the result of long-term monitoring begun in the late 1970s and early 1980s in the North Inlet Estuary, Georgetown County, South Carolina. The National Science Foundation funded the Long-Term Ecological Research (LTER) program in the North Inlet Estuary from 1981 to June, 1993. From 1993 to the present, the National Estuarine Research Reserve (NERR) Program has continued the support of the North Inlet-Winyah Bay monitoring. Each core database and its variables are listed below.

Real-Time and Archived Tide Data

Near Real-Time Tide Data (NOAA's Website)
     North Inlet Estuary Tide Gauge Station ID: 8662245; 6/2001-present:
         Real -time (six minute instantaneous) tide level above MLLW.  This link takes you to real-time data
        (1 hour delay). Select SC on the map and then Oyster Landing, SC (North Inlet Estuary) for data.

NOTE:  to those who work with tidal data and tidal datums: The National Tidal Datum Epoch has been updated to the 1983-01 epoch on April 21, 2003. The updated bench mark sheets are available on the CO-OPS website. A notice is posted on the main page of the website, with the following link: http://co-ops.nos.noaa.gov/datum_update.shtml.  Support to purchase the water level measurement system provided by NSF Grant No. 9907650.
