During expedition SCAN 2013, two gravity cores were collected in the Ona High slope, central Ona Basin, NE prolongation of the Antarctic Peninsula. Core TG-01 is 400 cm long and was collected from 2160 m water depth at 60º22'23.9314''S, 53º02'15.2501''W; core TG-03 is 295 cm long and was obtained from 2789 m water depth at 60º11'23.4003''S, 53º10'49.0810''W. Non-destructive analyses (i.e., physical properties measurements and X-ray fluorescence scanning) were performed on the archive halves. Both, physical properties (magnetic susceptibility, gamma-ray density, electrical resistivity and P-wave velocity) and major element compositions were determined at 1-cm resolution on split core surfaces of the archive halves using a GEOTEK Multi-Sensor Core Logger (MSCL) 81 at the Spanish Geological Survey (IGME, Spain).
