_To.d termine for a surface burst the amount of blast energy
Instrument stations will be anchored in the lagoon at various
distances from ground zero, Wine close~in stations will each heve 68
ball crusher gages in groups of four spaced vertically from the water
surface to the bottom of the lagoon. The stations located beyond
approximately 10,000 ft from ground zero will contain from two to eight
pressure~time gagesisuspended at different depths in the water, Twelve
stations of pressure-timegages are planned.
2.8.3 Remarks
The actial spatial ‘distribution of stations will be determined
at a later date from the résults of high explosive experiments.
Project 1.4 will participate in‘Shots Union, Echo and Nectar. In
addition, a few stations may \beActivated for Shots Bravo and Yankee.

2.9.1 Ohjective
To determine the relative intensity af the long range acoustic
signals produced by surface bursts. An effort wit} be mede to determine
device yields relative to the GREENHOUSE and IVY shots, acoustic veloc-
ity, shot location and/or time.
2.9.2
Procedure
The USN Electronics Laboratory will be requested:to continue
observation and analysis of data at Pacific SOFAR stations.Similarly,
groups from Columbia University will undertake observations!
SOFAR Research Station.
2.9.3 Remarks
This project will be conducted off site and will participate in
all shots.
