USNS Josiah Willard Gibbs (T-AGOR-1)
Underbody aft showing the auxiliary propeller added during her
conversion to a research ship.
This propeller, which resembled an internally-mounted outboard
motor, could be rotated through 180 degrees and enabled the ship
to maneuver precisely at speeds from dead slow to four knots.
It was powered by a 200 horsepower diesel. Note the wrench in
use on the port main propeller.

Underbody aft showing the auxiliary propeller added during her
conversion to a research ship.
This propeller, which in this view is trained partially to port,
enabled the ship to maneuver precisely at speeds from dead slow
to four knots. Note the wrench in use on the starboard main propeller
and the work underway on the starboard shaft bearing.

Complete view of the above-decks components of the ship's deep-sea
winch, probably shown just following installation in around late
1959.
This, the largest and heaviest deep-sea winch used up to this
time by the U.S. for oceanographic research, could carry up to
40,000 feet of wire rope in storage reels below decks and could
handle a 40,000 pound maximum load.

Dr. H. B. Stewart of the Coast and Geodetic Survey, on the left,
viewing the tractor winch component of the ship's deep-sea winch
during installation in around late 1959.
Note the numerous turns of the wire around the two drums of this
winch that were necessary to give the device enough traction
to handle its designed 40,000 pound load.

Team conducting at-sea tests of the ship's deep-sea winch, probably
soon after installation in around late 1959.
The test team is preparing the winch's cable for attachment to
a tug boat. The subsequent strain test showed that the winch
was capable of handling 45,000 pounds, 5,000 pounds over its
designed limit.

Crewman lashing a spare anchor to the cable guide for the ship's
deep-sea winch.
The cable guide appears to have received much hard use since
its installation in around 1959, and the anchor was probably
needed to provide it additional strength and rigidity. The cable
guide supported the cable between the tractor winch, visible
behind the crewman, and the "O" frame on the ship's
stern.
