The sea bottom samples were collected with a 60L Van-Veen grab (Fig.17) and with a 1.2T gravity corer mounted with a3m pipe (Fig.18. Whenever possible one or two sub-cores were taken on the grab sample (Fig.17, right).
The sample locations are shown in Figg.4 and are reported also in Tab.9 in Appendix 6.2.
Core 02 was measured for magnetic suceptibility 
(2cm resolution) using the ISMAR's
automatic logger SAAS-01 by a Bartington loop sensor [Masini L. (2001)]. (adimensional)
measures the capability of the material to become magnetized and to produce a
noise in the inducing magnetic field. Knowing and density, is it possible to
determine the mass susceptibility. The obtained data were corrected for
the loop sensor diameter (10 cm or 12,5 cm) and the sediment thickness, cleaned, filtered and
plotted against core depth.
