Cheeca Rocks Mooring (24.90°N, 80.62°W)
Cheeca Rocks is an inshore patch reef within the Florida Keys National Marine Sanctuary (FKNMS) off of Islamorada, Florida. The inshore patch reefs of the upper Florida Keys are of particular interest to resource managers given that they have maintained comparably high living coral cover relative to those reefs farther offshore. Scientists have been actively studying why these inshore patch reefs have been more resilient to the multiple stressors that have negatively impacted coral reefs across the Caribbean Sea over the past three decades, including coral disease, coral bleaching, and overfishing. A MAPCO2 buoy was deployed at Cheeca Rocks in the Florida Keys in December 2011. This is the second study site of the Atlantic Ocean Acidification Test-Bed (AOAT) that monitors ocean acidification in sensitive coral reef environments through a joint effort between PMEL, AOML, the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies (CIMAS), and NOAA's Coral Health and Monitoring Program. The AOAT provides high-resolution characterization of the carbonate chemistry that will be utilized to achieve the climate and ecosystem monitoring requirements of the National Coral Reef Monitoring Plan (NCRMP) of NOAA’s Coral Reef Conservation Program, and the newly formed Ocean Acidification Program (OAP).
On December 7, 2011, a surface seawater pH sensor was added to the Cheeca Rocks 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.
