To advance our scientific understanding of the ocean carbon cycle and how it is changing over time in support of NOAA's commitment to improve the Nation's ability to anticipate and respond to climate impacts and to conserve and manage healthy oceans, coastal ecosystems, and marine resources. Our research includes documenting the evolving state of the ocean carbon chemistry with high quality measurements on ships and autonomous platforms, studying the processes controlling the role of the ocean in the global carbon cycle, and investigating how rising atmospheric CO₂ and climate change affect the chemistry of the oceans and its marine ecosystems.
