The sea bottom was sampled with IGM's 1.2T gravity [12] (Fig.23) and a 1.5T Piston corers (Fig. 24 and 25), capable to be armed up to lengths of 10 and 20 M, respectively. IGM's Mod. SW104 [11](Fig.26 and 27) sediment/water corer was used also for collecting some key, undisturbed sections of the youngest sedimentary layers.. The type of the corers, including the choice of different pipe lenghts (2-3-4-6 M) and the gravity or bottom-triggered free-fall, varied upon the different sub-bottom conditions as depicted by site survey data. The velocity of descent of the corers ranged between 0.4 and 1.0 m/sec.
Almost 2/3 of the collected cores passed through a GEOTEK Multi Sensor Core logger, for the measurement of physical properties of the sediment (density, P-wave velocity, etc.).
Four cores (IM02, IM03, IM05, PI40) were opened on board for description, photographs and preliminary analyses for lithology and fauna (Fig. 28). Core IM02 was sampled by the turkish colleageues. The cores IM02 and IM05 were sampled every 5 and 10 cm respectively.
The cores were stored on board in a refrigerated container (15 degrees) and were put into IGM's Core Repository at 4 Degrees upon arrival in Bologna.
