Approximately 75 percent mud, 23 percent Mn pavement, 2 percent outcrop, and 1 percent ice rafted debris (IRD); Problems with wire out monitor, difficult to get accurate wire out readings. Several tension pulls over 9000lbs and abrupt release suggesting bites of outcrop between 3780-3750m; fault block; Arctic Ocean, Amerasia Basin, along edge of Nautilus Basin, av 3800m water depth; greater than 50 degree slope on fault scarp on southern edge of Nautilus Basin.
