ABSTRACT
This article focuses on a new study which reveals that deep-sea volcanoes are an important source of atmospheric methane and also contributes to global warming. Eberhard Sauter of the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany, and his colleagues found a huge column of gas bubbles rising to the surface from HÃ¥kon Mosby. They used an echo sounder to get acoustic images of the plume. The gas inside the bubbles turned out to be methane, which was protected from oxidation by a tough skin around the bubbles. The bubbles eventually dissolved in surface waters, much of it probably ending up in the atmosphere.
