Two nuclear radiation detection instruments mounted on a temporary beneh built into the wardrobe space of the after officers' quarters (Fig. 6). 6. A bathythermograph which was a part of the equipment of the ship, Operation of the Ship: The projected crulse pattern pre- sented to the commander of the WALTON unusual navigational and operational problems, and the mechanics of the sampling at the various stations required close cooperation between personnel of the ship and of the survey team, It was calculated that to cover the fifty proposed stations in ten days, with a stop of approximately 30 minutes at each station, and with a pause for refueling at the midpoint, the Ship would have to maintain a speed of advance of fifteen knots. As the operational procedure was worked out the ship steamed be~ tween stations at 18 knots, reduced the speed to 15 knots at survey time (ST) minus twenty-five minutes, and further reduced the speed to 10 knots for a bathythermograph drop at ST minus 10 minutes. At ST the ship slowed to 5 knots and aitered course to put wind 30 to 90 degrees on the port bow, the drop side, cause the plankton net had the effect of a sea anchor. be- When the Ship was steadied, the port screw was stopped and the starboard engine was slowed to rpm for approximately 4 knots, or toa ¥ From report of Commander A.
