This animation
depicts how
ocean sound
data were
being brought
to you via
the Internet
in near-real
time. As
sound waves
were emitted,
they traveled
through the
SOFAR channel
to the hydrophone
array. The
array captured
the data
and transmitted
it via the
submarine
cable to
shore. After being compressed into an audible format, the data
was made available online for the public and researchers. Click

Live Sound Data
*Update:
A Cable connecting the hydrophone array on
Pioneer Seamount to the shoreline was severed and it was decided not
to repair the cable due to costs and the risk of disturbing the benthic
environment. However NOAA does continue to pursue underwater acoustic
experiments. For more information, please visit:
NOAA's
Acoustics Program
and
 Listen
to Chief Scientist Chris Fox discuss the
mysteries of sound in the sea during an
interview broadcast on BBC. (Select
programme three. Requires Real Player.)
The NOAA Pacific
Marine Environmental Laboratory (PMEL)
processed ocean sound data from the
Pioneer Seamount, 40 miles off the
coast of Central California, and made it
available over the Internet in near-real
time.
This page offers an
animation that depicts how this was being
done, and offers a direct link to the PMEL
Web page.
