| NBP9501-PC24 | Antarctica, Ross Sea | Feb. 22, 1995 | Piston | -76.60598 | 175.41695 | 520.0 | 2.0 | Authors interpret this entire core as reworked. Lithology from Figure 4 of Licht & Andrews (2002), NBP94-01, and NBP95-01 cruise reports.; Subangular medium basaltic pebble at 0.23-0.24, 0.24-0.25 and 1.75-1.76 m. Sharp upper contact. Structureless. Pebble content and sand size decrease downcore. Authors interpret this entire core as reworked. Lithology from Figure 4 of Licht & Andrews (2002), NBP94-01, and NBP95-01 cruise reports. |
