Drogue run, 24-25 October 1963, near USPHS Buoy 18 (Fig. 121)
On 24 October surface drogue V was set at 1253 about halfway
between USPHS buoys 17 and 18, and surface drogue III at Buoy 18
at 1400. The drogues were recovered on 25 October. During
this run positions were obtained by a combination of dead
reckoning and radar range and bearings on Buoy 18.
Drogue V drifted an apparent 5.4 miles during the 23 hours
37 minutes it was adrift, to give an indicated surface current
velocity of 0.23 mph. Drogue III moved 4.8 miles in 21 hours
27 minutes, an indicated velocity of 0.22 mph.
The time-series of positions during this run was:
24 Oct. 1253 #V 43007.9', 87036.2? (set)
1400 #III 43008.01, 87024.4' (set, at Buoy l8)
25 Oct. 1127 #III 43011.3, 87021.0' (recovery)
1230 #V 43009.5', 87~30.'1 (recovery)
The wind regime applicable to this run was:
23 Oct. S 12 knots (diminishing during night)
24 Oct. S 9-18 k
25- Oct. SSW 88-12 k

gslue run 24-25 Jmne 1963 (.Pig.13): This run was designed to be a further test of the radio-drogue as well as a
test of the relative directions of deep and surface currents
off Grand Haven. Fresh batteries had not been put in the
transmitters, with the result-that the transmitters ran down.
Fortunately, a blind radio-call to the entire east side of the
