Hydrophone mooring deployment. |
Following
the successful use of the U.S. Navy's SOund SUrveillance System
(SOSUS) for monitoring low-level seismicity on the Juan de Fuca
Ridge, NOAA's Pacific Marine Environmental Laboratory has developed
a strategy for monitoring remote areas of the world ocean not
covered by fixed hydrophone arrays. This strategy requires the
deployment of moored, autonomous, hydrophones. In May, 1996
the array was successfully deployed in the eastern equatorial
Pacific to begin long-term monitoring of the East Pacific Rise
between 20N and 20S. In February 1999, an array of six hydrophones
was deployed in the North Atlantic between 15N and 35N and in
June 2002 an additional six hydrophones were deployed between
40-52N along the mid-Atlantic Ridge. Hydrophones were deployed
in the Gulf of Alaska for marine mammal monitoring in 2000. |
