Voyage to Southern Ocean aims to study air-sea fluxes of greenhouse gases
Date:2/26/2008

Scientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and vice-versa.

The cruise, which departs Feb. 28, should provide important information on how the greenhouse gas carbon dioxide moves between the ocean and atmosphere, said the cruises chief scientist, David Ho of Columbia Universitys Lamont-Doherty Earth Observatory. Comprising 30 percent of global seas, the Southern Ocean is a source of great uncertainty, he said. So its potentially important to our understanding of the global system.

Humans put about 6 billion metric tons of CO2 into the air each year, mainly by fossil-fuel burning and deforestation. About a third is thought to be absorbed by oceans, and a third by plants or other components of land. The rest stays in the airmuch of the reason why atmospheric CO2 is now building and climate is warming. However, there are huge uncertainties in the calculationsmade so far mostly through indirect means--and fluxes seem highly variable from year to year, with some parts of the oceans habitually giving up CO2 while others absorb it. (The Southern Ocean usually absorbs it.) "Understanding how atmospheric carbon dioxide reacts with these cold surface waters is important for determining how the ocean uptake of carbon dioxide will respond to future climate change, said Christopher Sabine, an oceanographer at the U.S. National Oceanic and Atmospheric Administration (NOAA). NOAA, NASA and the National Science Foundation are cosponsoring the cruise.

About 30 scientists from over a dozen institutions will traverse an area above Antarctica more than 1,000 miles east of Punta Arenas, aboard the 274-foot NOAA ship Ronald Brown. Here high, freezing winds unimpeded by landmasses roar much
