Abstract : On Mike shot of Operation Ivy measurement of underwater pressures was attempted at four loca tions near the floor of the lagoon. Gauges were installed at distances ranging from approximately 5700 to 112,000 ft from ground zero and about 1 mile from the reef. The single usable record showed sharp pressure spikes at 0.3 and 0/6 sec after zero time. Although the later spike cor responded with the time of arrival of the air shock at the surface of the lagoon above the gauge, no satisfactory explanation for the first spike has been found. Because two of the four gauges used were apparently faulty in their operation and the recorder to which a third was connected failed to start at all, it was impos sible to draw any conclusions regarding the nature or magnitude of the underwater shock.
