Description

The Southern Ocean plays an important role in the global carbon cycle and yet the timing, magnitude, and trends of key biogeochemical fluxes in this region remain poorly known due in large part to a lack of surface ocean data. The primary objective of this project is to collect observations of the partial pressure of carbon dioxide (pCO2) in the surface ocean needed to assess the current state and long-term change of the flux of carbon dioxide (CO2) between the atmosphere and ocean. Our measurements are focused in the North Pacific, Arctic, and Southern Oceans to better understand air-sea carbon fluxes over high-latitude oceans, a large uncertainty in future climate change scenarios. This project supports the ongoing operation and maintenance of the underway air-sea pCO2 systems installed on the RV/IB Nathaniel B. Palmer (NBP) and ARSV Laurence M Gould (LMG).

Field Season Overview

This project supports ongoing surface measurements of the partial pressure of CO2 (pCO2) from aboard the ARSV Laurence M. Gould and RV/IB Nathaniel B. Palmer. In addition, discrete measurements may be made from water samples collected underway.
