Physical properties of sediment cores TG-03, Ona Basin, southwestern Scotia Sea (Antarctica)

During expedition SCAN 2013, gravity core TG-03 was collected in the Ona High slope, central Ona Basin, NE prolongation of the Antarctic Peninsula. The core is 295 cm long and was collected from 2789 m water depth at 60º11'23.4003''S, 53º10'49.0810''W. Non-destructive analyses were performed on the archive halves. Physical properties (magnetic susceptibility, gamma-ray density, electrical resistivity and P-wave velocity) 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).在SCAN 2013科考航次期间，研究人员于南极半岛东北延伸段的奥纳盆地中部奥纳高斜坡海域采集了重力柱样TG-03。该岩芯总长295厘米，采集站位水深2789米，坐标为南纬60°11′23.4003″、西经53°10′49.0810″。研究人员对存档半芯（archive halves）开展了无损分析：依托西班牙地质调查局（IGME, Spain）的GEOTEK多传感器岩芯记录仪（Multi-Sensor Core Logger, MSCL）81型设备，在存档半芯的劈开岩芯表面以1厘米的分辨率测定了其物理性质参数，包括磁化率、伽马射线密度、电阻率与纵波速度。
