SEA BOTTOM SAMPLING

Sea bottom sampling was performed in the Area D and in the Area A. One gravity core was taken in the deepest portion of Cinarcik Basin. Area D was chosen because of the presence of presumably active faults. Two transects of respectively three gravity cores and four water/sediment cores were collected across two faults. The continental shelf Area A was sampled to investigate stratigraphic/structural features rising few meters above the surrounding, according to a possible interpretation as relict sand dunes or gas escaping mounds or biohermal reefs. Finally, the core on Cinarcik basin will provide a more complete stratigraphic record of the area. Some additional grab samples were taken troughout.

Fig.23 and 24 show some samples. The coordinates are reported in Tab.4.
