Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]

, 2003
It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...
