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.

When the
Ship was steadied, the port screw was stopped and the starboard
engine was slowed to rpm for approximately 4 knots, or toa
