...

• Report to LO/ALO for other port call duties.

Site Preparation

• Place log sheets and instrument's Quick Users Guide at each station. Organize prior Expedition's log sheets (if not already done so) for shipment back to IODP.

• Make sure that the motion control systems have found home and the position of the laser for all instruments using M-Drive.
• Perform calibrations for all tracks prior to first core on deck at each Site.
