| Abstract: | Two pockmark fields, located along the coastal zone of the Patras and Corinth gulfs, Greece were surveyed in detail. The pockmark fields, which are 30 km apart, are formed in shallow waters at depths of 20–40 m and are about 0.5–1 km from the shoreline. The oceanographic data suggest that two different mechanisms were responsible for their formation. The pockmark field in the Patras Gulf appears to have been formed as a result of methane seepage from the seabed, whereas the field in the Corinth Gulf appears to have resulted from groundwater seepage. |
