Project: Southern Ocean Gas Exchange Experiment

Acronym/Short Name:SO_GasEx

Project Duration:2008-02 - 2008-04

Geolocation:Southwest Atlantic sector of the Southern Ocean (nominally at 50°S, 40°W, near South Georgia Island)

Description

The Southern Ocean Gas Exchange Experiment (SO-GasEx; also known as GasEx III) took place in the Southwest Atlantic sector of the Southern Ocean (nominally at 50°S, 40°W, near South Georgia Island) in austral fall of 2008 (February 29-April 12, 2008) on the NOAA ship Ronald H. Brown. SO-GasEX is funded by NOAA, NSF and NASA.

The research objectives for Southern Ocean GasEx are to answer the following questions:

What are the gas transfer velocities at high winds?
What is the effect of fetch on the gas transfer?
How do other non-direct wind effects influence gas transfer?
How do changing pCO2 and DMS levels affect the air-sea CO2 and DMS flux, respectively in the same locale?
Are there better predictors of gas exchange in the Southern Ocean other than wind?
What is the near surface horizontal and vertical variability in turbulence, pCO2, and other relevant biochemical and physical parameters?
How do biological processes influence pCO2 and gas exchange?
Do the different disparate estimates of fluxes agree, and if not why?
With the results from Southern Ocean GasEx, can we reconcile the current discrepancy between model based CO2 flux estimates and observation based estimates?

The SO-GasEx cruise report and Science and Implementation plans, may also be available at the SO-GasEx science Web page.
