Abstract Free gases from fumaroles of the Tavurvur and Rabalanakaia volcanoes are liberated as bubbles from the seafloor of Matupit Bay. The free gases contain methane (as high as 0.02%), heavy hydrocarbons (0.00001–0.0004%), carbon dioxide (more than 90%), and hydrogen sulfide (up to 27.9%). Background levels of dissolved methane are 30–50 nl/liter; they become seven times higher in the area of sea-floor uplift in the bay, and 10–20 times higher in the hot-water lateral zone. The hydrogen concentration is as high as 100–300 nl/liter. Average content of carbon dioxide is 0.16–0.36 ml/liter and increases up to 5.5 ml/liter in the gasbubbling area.
