of 45° with the surface of the water.
For the subsequent drop
of the water sampling bottles the starboard engine maintained
rpm for speed of about 1 Ikmot.
After each drop the ship built
up slowly to the 18-knot cruising speed to avoid unnecessarily

cluded in the survey and the projected track of the ship were
determined at a meeting on June 9 in the offices of Captain
H. @. Munson, USN, representative of the commander of Task
Group 7.3.
Those present at the meeting included Captain Munson;
Commander N. Purley, naval liaison officer, CTG 7.1; Commander

of the HASL; Dr. A. V. Shelton, of TG 7.1; and Lauren R. Donaldson
and Allyn H. Seymour of ™ 7.1 (Program 35).
Determinations of area and track were made after consideration of the elements of the problem, such as fallout patterns and
estimated drifts
of radioactive materials,
and with knowledge
of such operational factors as the overall time limit on the survey, the speed of the ship, and the need of the ship for
