Gray's Reef Acidification Mooring off the Georgia Coast

SOCAN members Drs. Janet Reimer, Scott Noakes, and Wei-Jun Cai have partnered on this project since July 2006. The acidification mooring records nearly continuous CO2, pH, temperature, and salinity of the surface water at a frequency of every three hours. Observations from this project create a time series of information that allows researchers to determine overall trends in acidification over the last few decades, daily to seasonal variations, and predict how acidified waters could impact animals living within shelf waters of the South Atlantic Bight.


The Gray's Reef mooring is 40 nautical miles Southeast of Savannah and has operated since 2006 as a joint effort by NOAA's Ocean Acidification Program, NOAA's Pacific Marine Environmental Laboratory, NOAA's National Data Buoy Center, NOAA's Gray's Reef National Marine Sanctuary, SECOORA, the University of Georgia and the University of Delaware.

COIncrease at the Gray's Reef Mooring 

CO2 at the Gray's Reef mooring has been increasing since 2006. This increase has led to a decrease of surface water pH, thus the waters around the mooring have become more acidic. Periodic cruises to the mooring allow researchers to clean and maintain the equipment as well as collect additional water samples to aid in the detection of long-term changes in the water chemistry. The Gray's Reef mooring is also part of the National Data Buoy Center's (NDBC) network where data such as wind, wave height, and other weather information can be downloaded.
