Scientists
monitoring earth
movements in Antarctica
say
they've found
a singing iceberg.
The
sound waves
cannot be heard
by
humans, a
frequency of 0.5 hertz
but
they resemble
a swarm of
bees
or an
orchestra warming up.
"Once
the iceberg
stuck fast, it
was
like a
rock in a
river,"
she said.
"The water pushes
through
its crevasses
and tunnels at
high
pressure and
the iceberg starts
singing.
The tune
even goes up
and
down, just
like a real song."
