JR298-PC726 (PC726 CORE_NO 726) * Latitude: -69.531700 * Longitude: -93.915800 * Date/Time: 2015-02-09T00:00:00 * Elevation: -3663.0 m * Recovery: 12 m * Location: Bellingshausen Sea, Near crest of mound (IODP 732-FULL2 site BELS-2C) * Campaign: (JR298) * Basis: * Method/Device: Piston corer (PC) * Comment: 8 sections (0-150 cmbsf, 150-300 cmbsf, 300-450 cmbsf, 450-600 cmbsf, 600-750 cmbsf, 750-900 cmbsf, 900-1050 cmbsf, 1050-1200 cmbsf); 1 core-top sample (disturbed; ca. 3 cm thick, stored in end cap in bag); 1 core-top suspension and sediment sample (disturbed, stored in bag); 2 core catcher samples; NOTE: thickness of core-top material could not be estimated reliably and therefore section depths were not corrected
