Abstract : Barometric and water-surface waves generated by Mike shot were studied by means of 25 instruments in 19 locations in the Pacific Basin ranging from 12 to 4600 nautical miles from Ground Zero. Several new kinds of instruments were constructed and used, and deep-sea instrument stations were installed on the tops of two mounts. The first water waves arriving at Eniwetok Island apparently traveled along paths outside the lagoon. At several of the stations there were two distinct arrivals of water waves, the first apparently being driven by the propagated rise in atmospheric pressure caused by the explosion and thus traveling at the speed of sound and the second moving along the water surface in the usual manner at a velocity of the square root of gh. At the distant island stations a long-continued persistence of wave activity substantially above background was observed, modulated by sporadic enhancements that suggest reflections from major land masses.
