4.2.1
Cbhjective
To obtain dimensional data on craters formed by nuclear detonations for use in developing a generalized "theoretical-empirical"
means of predicting cratcr dimensions.
Frocedure
.dwo measuring techniques will be used for this project.
These
thoto Interpretation The army Map Service will employ stereoscopic photogrammetry
to map theforaters.
By this technique it is expected to obtain the
erater diameters for Bravo, Union, “cho and Koon and some detail of the
crater lips’ for Bravo, “cho, and Koon.
b. “Fathometer Traverse -
én LGU: equipped with a MK-6 fathometer will traverse the
craters formed ati Bravo, Union, and Koon.
The position of the LCU
will be correlatedwith the fathometer soundings by use of "Ray dist."
