Pausanias (Attica)

Volcano: Methana (see Methana at the Smithsonian Institution website in a new tab)
Type: Bubbling Water
Description: Gas bubbling in the water of a thermal bath on the northern coast of the peninsula of Methana. The spring emerges very close to the sea and is captured with a small pool (about 2 m^3) inside a small building. The pool is about 90 cm below the threshold of the small entrance of the building. It has no artificial water outflow and the water in the pool has generally cooled. To drive new warm water into the pool, it has to be emptied manually or with an electric pump. The thermal water flows very slowly but eventually fills the pool. Sometimes in the freshly filled pool, gas starts to bubble. Sometimes gas accumulates above the water without visible bubbling: When the sea is calm, train of bubbles can be also observed in water close to the shore. About 50 m to the east along the coast there is a small well about 2 m deep. On the bottom no water has been found but CO2 accumulates up to concentrations of > 70%. In springtime the bottom is totally covered by dead insects and the bones of a dead animal (dog?) have also be found.
