The Val d Agri area is well-known for oil exploration. An old 500 m deep exploration well in the northern part of
this area has been used for long-term hydrogeochemical investigations. The well is ch...
Mud volcanoes and methane seeps in Romania: main features and gas flux

Romania is one of the European countries with the most vigorous natural seepage of methane, uprising from
pressurised natural gas and petroleum reservoirs through deep faults. The largest seepage zon...

A sea-ice model is used to investigate the ice-ocean heat flux that occurs at the base of the ice. The source of this basal heat flux is supposed in reality to arise from physical processes (e.g. ocea...
