Title :
DEEP-LEVEL STUDIES OF
ELEMENTARY PARTICLES IN LAKE BAYKAL
Primary source: Pravda, March 5,
1982, No. 64 (23225), p. 2, cols. 6-8
Extract: A new contingent of scien-
tists has begun work in the southwest
part of Lake Baykal.
Associates
of
the Limnology Institute and the
Siberian Institute of Earth Magnetism,
the Ionosphere and Propagation of
V
Radio Waves are drilling through the
thick ice of the lake.
Their task
is to study properties of the ice
and features of processes taking
place in the water under its solid
surface.

"The decision has been made to
create a station near Marituy
Settlement, east of Cape Stolba,
for detecting and recording elementary
particles -- muons and neutrinos --
at deep levels of the water,"
reported G. Galaziy, a corresponding
member of the USSR Academy of
Sciences and director of the
Limnology
Institute.
"This work
will be pursued in accordance with
the Dumande international program,
with specialists of a number of
countries participating. The
contingent of limnologists and
physicists is also studying the
strength of the ice, for the purpose
of issuing recommendations regarding
the installation and transporting of
apparatus in the winter."
The strength of rays of the sun
penetrating the ice layer also
requires careful evaluation. The
water is heated by two degrees under
pure ice one meter thick, which
transmits solar radiation well.
As a result, photosynthesis of algae
takes place and fish eggs develop,
which reduces the transparency of
the water. It was thought up until
recently that the ice impeded heat
radiation emitted by the bottom of
Lake Baykal.
It was presumed that
a kind of greenhouse effect occurs
and the uppermost layer of the water
is heated.
"Our experiments have not con-
firmed the existence of this
phenomenon, " said Candidate of
Physical-Mathematical Sciences
P. Sherstyankin, the head of the
contingent. "It has been established
that cracked ice 'functions' as a
prism, a trap for rays of the sun.
Rays penetrating the water can emerge
in the opposite direction only at a
strictly determined angle. A light
field is thus created under the ice.
"The detection of muons and of
flows of neutrinos coming from the
sun and stars is of great significance.
These perpetual wanderers and envoys
from outer space help to interpret
the structure of space, as well as
processes taking place in the universe.
Knowledge of these processes is also
of practical interest.
"Take, for example, muons --
elementary particles which originate
in the interaction of cosmic rays
with the matter of the earth's
atmosphere.
These rays are capable
of penetrating our planet to a depth
of kilometers, probing the upper
layers of the earth's crust by
radiation. With the aid of muons,
one can pursue geophysical prospect-
ing of minerals, check the correct-
ness of the drilling of tunnels
through rock, and determine more
precisely the boundaries of ore
bodies and of water supplies in the
snow cover of almost inaccessible
mountain regions from which avalanches
and mudslides descend."
