Methane (CH4) is a potent greenhouse gas. Its release from aquatic sediments to the water column and potentially to the atmosphere, is a subject of great concern. A coupled macroscopic single-bubble mechanical/reaction-transport numerical model was used to explore the ascent of a mature CH4 bubble t...
