National Coral Reef Monitoring Program: NCRMP and OAP Class II Carbonate data collected near Bird Key Reef in the Dry Tortugas, from 2015-09-02 to 2015-09-05. (NCEI Accession 0157742)

OA is expected to reduce the calcification rates of marine organisms, yet we have little understanding of how OA will manifest within dynamic, real‐world systems, nor how to accurately measure said manifestation. This data includes collections of water samples from autosamplers deployed at a specified location set to collect every six hours near Bird Key Reef in the Dry Tortugas. These samples provide characterization of the carbonate chemistry that is utilized to achieve the climate and ecosystem monitoring requirements of the National Coral Reef Monitoring Plan of NOAA’s Coral Reef Conservation Program, which supports this project along with NOAA's Ocean Acidification Program.
