absorption coefficients of hot gases for the analysis of
nuclear fire balls and other high temperature sources.
The research carried out included a theoretical
calculation of the absorption coefficients of air for
temperatures from 1000 to 12,000{sup 0}K and for
densities
from 10 to 10{sup

Operation Redwing was made concerning light absorption
shells in air after passage of shocks from nuclear
explosions. Experimental studies were made by the
observation of spectra under shock tube conditions to
ascertain optical properties

As a part of the 1957 Office of Naval Research
survey of Eniwetok Atoll,
seismic measurements
were made to determine the bottom reflectich
coefficients on the outside southwest slope of the
atoll. The values of the reflection coefficients are low
and irregular and have been related to bottom structure.
Reflections from several very thin shallow layers and
from deeper layers were observed indicating a submarine
geology agreeing with that found previously by other
