Realtime Observations

Various water and meteorological parameters related to the Long Bay area are collected in realtime through several partner organizations. Here you can find up-to-date observations related to dissolved oxygen concentrations, salinity, water temperature, wave speed, direction, weather information and more through the data displayed or by clicking on one of the following links. These data will provide a general idea of the current conditions in the area.

Monthly data files in CSV(Comma Separated Value)/Excel format
Time series graph products

Data from the Springmaid Pier sensor package is currently not available in real-time. However data are being continually collected and archived. These will be made available in the monthly CSV/Excel format and graph products noted above in the near future. Efforts are presently being made to restore the real-time reporting capabilities of the sensor.

SCDNR/Apache Pier Cooperative Real-Time Temperature and Salinity Monitoring Station

In July of 2004, fishing pier owners along the Grand Strand began reporting unusually large catches of Southern Flounder at their respective fishing piers. Water quality data suggests this anomaly was a direct response to hypoxic conditions that initiated offshore and moved inshore, effectively herding the flounder toward the coast. In response to the "Grand Strand Flounder Anomaly of 2004", the South Carolina Department of Natural Resources (SCDNR) in cooperation with the owners of Apache Pier have installed a real-time temperature and salinity (conductivity) monitoring station. One sonde has been positioned near the bottom and the other has been installed on a float so as to remain near the surface regardless of tide level. These sondes collect and transmit real-time temperature and salinity measurements every fifteen minutes, 24 hours a day, to this website. It is our hope that this monitoring station will serve as an early warning device to alert the proper authorities to future low dissolved oxygen events. In addition, this station will serve the fishing public by supplying real-time water conditions continuously through out the year.

The Southeast Atlantic Coastal Ocean Observing System (SEACOOS) is a regional partnership formed to foster and promote the development of the coastal observing system for the Southeastern U.S. (NC, SC, GA, FL), and to advance scientific understanding of the SE coastal ocean processes and systems. SEACOOS will support the national need for improved environmental information from the coastal ocean, and facilitate access to this information for the Southeastern Atlantic region. SEACOOS has been organized around the four central functions (or sub-systems) defined in various integrated ocean observation system (IOOS) planning documents: Observations; Modeling; Information Management; and Outreach and Education. Near-realtime oceanographic and meteorological data, as well as modeling applications are available on the website.


The Carolinas Coastal Ocean Observing and Prediction System (Caro-COOPS) is based upon an instrumented array of coastal and offshore moorings, which are being deployed off of the coast of the Carolinas. The information from this observing system will be used to monitor and model estuarine and coastal ocean conditions, as well as develop predictive tools and ultimately forecasts for coastal managers. Caro-COOPS also includes a sophisticated information management infrastructure designed to process and deliver information to a variety of public users, as well as to model applications. Near-realtime oceanographic and meteorological data, as well as modeling applications are available on the website.


The University of North Carolina Wilmington's Coastal Ocean Research and Monitoring Program (CORMP) was initiated as a research and observation program focusing on the collection of data applicable to physical and ecological predictive models, fisheries sustainability, and habitat quality. CORMP capitalizes on a combination of instrumented moorings, remote sensing and ecosystem models, and traditional ship-based observations to establish baseline conditions, identify responses to stochastic events, predict and verify long-term trends and identify linkages among coastal ocean ecosystem components. Near-realtime oceanographic and meteorological data, as well as modeling applications are available on the website.

Carolinas Coast (beta)

A partnership among Caro-COOPS, CORMP, SEACOOS, and the NOAA NWS Wilmington Weather Forecast Office, Carolinas Coast is a "one-stop shop" for coastal, resource, and emergency managers; mariners; educators; beach goers; and other prospective ocean and coastal user groups. From the website, the maritime community will have access to a wide range of near real-time and archived marine observations. Near real-time data on coastal weather and oceanographic conditions, tides, forecasts, and coastal hazards are available on the website.

USGS Realtime Surface Water Data

Real-time streamflow data for South Carolina typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival.

USGS Realtime Water Quality Data

Real-time water-quality data are returned directly from field instruments. Instantaneous data are recorded at 5-minute to 1-hour intervals and uploaded to the data base every 4 hours.
