Coastal Mississippi Buoy (30°N, 88.6°W)

The Central Gulf of Mexico Ocean Observing System (CenGOOS) station CenGOOS-01 was initially established in December of 2004 with funding by the Office of Naval Research, with subsequent funding through NOAA. The buoy has survived two hurricanes (Katrina in 2005 and Gustav in 2008), and although damaged, was repaired and redeployed each time. The 3 m discus buoy USM3m02, with the NOAA MAPCO2 instrument package, was deployed at station CenGOOS-01 on April 30, 2009 from the R/V Tommy Munro.

On March 18, 2011, a surface seawater pH sensor was added to the Coastal Mississippi Mooring mooring. By measuring pH in addition to pCO2, we are able to more accurately and precisely study the changes associated with ocean acidification. All seawater pH observations are shown in the second figure below. This project is supported by NOAA's Ocean Acidification Program. In July 2017 this site was discontinued and the buoy platform and sensors were moved to nearby coastal LA.
