ABSTRACT
The need for accurate and undisturbed core samples has led to the development of this new coring method with controlled penetration speed (Angel Descent), to minimize the sediment shortening and deformation. The results of the last campaign are herein discussed, analyzing recovery/penetration ratio, acceleration data of the corer during penetration, and logs of magnetic susceptibility on the samples obtained using two different methodologies in the same location. The purpose of this paper is to compare the performance of the two sampling methods, to identify which system allows for less axial deformation of soils and less distortion of the structures, to obtain a geometrically unaltered sedimentary sequence.
