The problem of multiple regression analysis where the dependent and
independent variables are components of a two dimensional vector is
discussed, and a complete statistical development of the solution of
estimators for the parameters in the model is given. The theory regarding
predictions and confidence statements about such predictions is also
developed. A computer code was written for the IBM 704 computer which
solves the above problem and a description of the code is given. The
statistical model was applied to a meteorological problem in wind ‘
forecasting at the Eniwetok Proving Ground, and prediction equations were
developed and evaluated. (auth)

>The true wave travel times in the western region of the Pacific are 2
sec less for P waves. 5 sec less for P P
waves. and 3 sec less for PcP
waves than those given by the Jeffreys-Bullen hodograph. The travel times
of transverse waves are 4 to 5 sec higher. The corrections for longitadinal
waves are based on the absence of a granite layer in the Pacific Ocean,
while for the transverse wave it must be related to the value of the travel
rate of S waves in the upper layer. (R.V.Jd.)

A study was made to determine the amounts of radioactivity in marine
algae,
water,
and lagoon bottom sand collected at Eniwetok Atoll during the
period April 1954 to April 1956. The highest levels of beta radioactivity
of algae collected after the detonation of a nuclear device (Nectar) were
in algae from those islands closest to the site of detonation and in the
downwind path of the fallout. With time after detonation, the decline of
radioactivity in the algae at Belle Island was faster than can be accounted
for on the basis of physical decay alone.
sand collected in the deeper waters
In March 1955,
(20 to 140
feet)
algae and bottom
of the lagoon,
one
half to two miles offshore, contained as much or more radioactivity than
samples collected in the shallow water near shore. The radioactive decay
rates of algae samples collected from Leroy and Henry Islands were greater
than those of algae from other islands, indicating that there was less
residual contamination from previous detonations at these two islands.
Study of the radioactive decay rates of the algae at Belle Island showed
