For the last 20 years, civilian researchers have used the Sound Surveillance System (SOSUS), a US Navy hydrophone array deployed for anti-submarine warfare during the Cold War, to detect seismic and volcanic activity in the Northeast Pacific Ocean. A

Vocalizations resembling known Bryde's whale sounds were recorded on autonomous hydrophones at seven sites in the eastern tropical Pacific. Five short (3 s) low-frequency (80 Hz) "phrase" types were observed. "Swept alternating tonal" phrases include

Blue whales, Balaenoptera musculus , in northeast Pacific waters often produce a two-part call. The first part, A, is amplitude-modulated, lasting about 17 s, and the second part, B, is frequency-modulated, lasting about 19 s. Type B calls are more e

Since 1999 six Sound Fixing and Ranging (SOFAR) hydrophones have been moored along the Mid-Atlantic Ridge (MAR) (15-35 N). These hydrophones (8-bit data resolution) are designed for long-term monitoring of MAR seismicity using the acoustic T waves of

An acoustic survey for sperm whales was conducted in the Gulf of Alaska. Six autonomous hydrophones continuously recorded sound signals below 500 Hz from October 1999 to May 2001. After recovery, recordings were processed using an automatic process t
