The mission of the Carbon Program at NOAA’s Pacific Marine Environmental Laboratory is to understand the changing chemistry of the oceans. Without the ocean’s uptake of carbon dioxide (CO2) emissions, the globe would have already reached over 1.5oC warming, along with the significant risks and impacts that are predicted to come with it. Yet key uncertainties in the ocean’s service of CO2 uptake remain to be addressed in order to track global sources and sinks of CO2 and detect how the ocean CO2 sink is changing over time. This research opportunity focuses on characterizing variations in air-sea CO2 flux across time and space. Approaches include using machine learning applications to assess global ocean CO2 uptake estimates and using new autonomous ocean observing technologies to better understand natural variability and long-term trends.
