ObjectivesTwo previous reconnaissance cruises using GLORIA in the Eastern Mediterranean had indicated a band of well defined structural gain extending along the Hellenic Outer Ridge, as well as showing the presence of two other similar outer ridges. The purpose of the present cruise was to test and extend the tentative earlier conclusions by obtaining more data. In geographical terms it was necessary to determine a) the limits of the Calabrian Outer Ridge b) the relationship of the Hellenic Outer Ridge to its possible analogue in the Ionian Isles of Western Greece c) the location of any features attributable to salt tectonics d) the realtionship of the Hellenic and Cyprus outer ridges and e) the form and trend of structures in the Hellenic Trough Complex.
