Research Locations: Drake Passage


Description

The Southern Ocean plays a key role in modulating the global carbon cycle, but the size and even the sign of the global ocean flux in terms of the atmospheric burden of man-made carbon dioxide is still uncertain. This is in part because of lack of measurements in this remote region of the world ocean. This project continues a multi-year time series of shipboard chemical measurements in the Drake Passage to detect changes in the ocean carbon cycle and to improve the understanding of mechanisms driving natural variability and long-term change in the Southern Ocean.


Field Season Overview

This project supports ongoing surface measurements of the partial pressure of CO2 (pCO2) from aboard the ARSV Laurence M. Gould. In addition, discrete measurements will be made from water samples collected underway. One participant may attend a vessel port call and one participant may sail on a cruise to perform maintenance on the system.
