Abstract
In an intensifying effort to track ocean change and distinguish between natural and anthropogenic drivers, sustained ocean time-series measurements are becoming increasingly important. Advancements in the ocean carbon observation network over the last decade, such as the development and deployment of Moored Autonomous pCO2 (MAPCO2) systems, have dramatically improved our ability to characterize ocean climate, sea-air gas exchange, and biogeochemical processes. The MAPCO2 system provides high-resolution data that can measure inter-annual, seasonal, and sub-seasonal dynamics and constrain the impact of short-term biogeochemical variability on carbon dioxide (CO2) flux. Overall uncertainty of the MAPCO2 using in situ calibrations with certified gas standards and post-deployment standard operating procedures is less than 2 µatm for seawater partial pressure of CO2 (pCO2) and less than 1 µatm for air pCO2. The MAPCO2 maintains this level of uncertainty for over 400 days of autonomous operation. MAPCO2 measurements are consistent with ship-board seawater pCO2 measurements and GLOBALVIEW-CO2 boundary layer atmospheric values. Here we provide an open ocean MAPCO2 data set including 14 surface buoys from 2004 through 2011 and a description of the methods and data quality control involved. The climate quality data provided by the MAPCO2 has allowed for the establishment of open ocean observatories to track surface ocean pCO2 changes around the globe.
