Operation HARDTACK, April-October 1958, Project 1.3. Surface Phenomena from Underwater Bursts (Sanitized Version)

摘要

The primary objective was to record and measure the formation, growth, and dissipation of the visible surface phenomena during Shots Wahoo and Umbrella by means of timed technical photography. The secondary objective was to obtain a better understanding of the nature of the base surge by recording the temperature and humidity at various positions in the surge clouds formed by the collapse of the plumes on Shot Wahoo and the collapse of the column on Shot Umbrella.
