Gas geochemistry of shallow submarine vents in the Aegean sea (Greece)

Research output: Contribution to conferenceOtherpeer-review

Abstract

The Aegean area, which is geodynamically very active, is characterised by intense seismic activity, presence of active volcanic systems and anomalous geothermal gradients. Like other regions of intense geodynamic activity it is also characterized by extensive geogenic degassing. Gas manifestations are not only widespread on land but are also very frequent underwater. Many of these, as for example those of Milos and Santorini, are known since long time and have been previously studied although the targets were generally the hot waters or the sediments affected by the emissions (Smith and Cronan 1978, Dando et al. 1995, Price et al. 2013, Megalovassilis 2014).The present study aims at producing the first catalogue of the shallow submarine gas manifestations of the Aegean Sea andto characterizegeochemically the emitted gases.
