Figure F2. Schematic cross section of the upper portion of an advanced piston corer (APC) core barrel filled with a sediment core, illustrating how gas bubbles will migrate out of the sediment and move upward along the side of the core liner to accumulate at the top of the core barrel under the face of the APC piston. TP = thermistor probe, CS = conductivity sensor.
