Research Locations: Drake Passage / Southern Ocean Pacific Sector


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

Project participants deploy to one port call each year for each vessel to perform maintenance on their underway instrument. For most of the year, onboard ASC technicians monitor the equipment, turn it on and off to avoid data collection in other nations’ Exclusive Economic Zones (EEZ), and perform maintenance as needed. At the end of each cruise the data is distributed to the project PIs and collaborators as well as the onboard science parties.
