NOAA’s Ocean Acidification Program
Visitors to Florida Keys National Marine Sanctuary may notice a recent addition to the reef near Cheeca Rocks: a sophisticated new monitoring buoy. NOAA scientists from the Atlantic Oceanographic and Meteorological Laboratory and partners from the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies deployed the buoy in December 2011 under permit from the sanctuary. The large yellow ‘MApCO2’ buoy sits roughly three feet above the waterline and along with subsurface instruments, simultaneously measures the concentrations of carbon dioxide in the atmosphere and ocean. Divers and boaters are asked to keep clear of the buoy.
Ocean researchers are studying ocean acidification — changes in ocean chemistry resulting from rising levels of carbon dioxide in the atmosphere then absorbed by the ocean. The Cheeca Rocks buoy is part of the Atlantic Ocean Acidification Test Bed,funded by NOAA’s Coral Reef Conservation Program.
