summary the passage and the lecture qLQXE
The passage mentions several sources for sounds that the Russian submarine crew was hearing from 1960 till 1980, but the lecture has a different point of view.
First, the passage states that these noises were related to female orca whales which were trying to call males. However, the lecture states that the whales' population lives near the surface of the water but the submarine was moving in deep water while the crew was hearing the noises. Therefore, it seems strongly unlikely for the crew to hear sounds from shallow waters.
Second, the passage mentions that the sound could be because of giant squids that have soft bodies without skeletons, so, the sonar would not show these animals. This contradicts the lecture that states noises were audible between the 1960s till 1980s and for two decades. It mentions that squids always lived in those waters, and still are living there. But, crews started to hear those sounds for a while and then stopped hearing them. So, if it was related to squids, it should have never been cut off.
Third, the passage argues that those sounds were produced by another submarine that was probing the area and was using a technology that did not show on the Russian submarine's sonar system. However, the lecture states that since the source of the sounds was changing so quickly and in different dimensions, it could not be related to another submarine, because submarines cannot change directions so fast. It also mentions that even today technology is not advanced enough to make a submarine with no engine sound. But crews were not hearing any sounds from a submarine's engine, so, the noise could not be caused by another submarine.
The
passage
mentions
several sources for
sounds
that the Russian
submarine
crew
was hearing
from 1960 till 1980
,
but
the
lecture
has a
different
point of view.
First
, the
passage
states
that these
noises
were related
to female orca whales which were trying to call males.
However
, the
lecture
states
that the whales' population
lives
near the surface of the water
but
the
submarine
was moving in deep water while the
crew
was hearing
the
noises
.
Therefore
, it seems
strongly
unlikely for the
crew
to hear
sounds
from shallow waters.
Second, the
passage
mentions
that the
sound
could be
because
of giant squids that have soft bodies without skeletons,
so
, the sonar would not
show
these animals. This contradicts the
lecture
that
states
noises
were audible between the 1960s till 1980s and for two decades. It
mentions
that squids always
lived
in those waters, and
still
are living there.
But
,
crews
started
to hear those
sounds
for a while and then
stopped
hearing them.
So
, if it
was related
to squids, it should have never been
cut
off.
Third, the
passage
argues that those
sounds
were produced
by another
submarine
that was probing the area and was using a technology that did not
show
on the Russian submarine's sonar system.
However
, the
lecture
states
that since the source of the
sounds
was changing
so
quickly
and in
different
dimensions, it could not
be related
to another
submarine
,
because
submarines
cannot
change
directions
so
fast
. It
also
mentions
that even
today
technology is not advanced
enough
to
make
a
submarine
with no engine
sound
.
But
crews
were not hearing
any
sounds
from a submarine's engine,
so
, the
noise
could not
be caused
by another
submarine
.
