Sounds from the Sea

Ever wanted to listen in on the ocean?

• Blue whale A/B calls (at 10 times normal speed)
• Fin Whale pulses (at 10 times normal speed)
• Ocean background noise, recorded 9/3/99 ~~21:27 UTC)
• Magnitude 4.6 earthquake, 5/28/98, 01:31PM PDT, located 2 miles S of San Juan Bautista, CA. Hypocentral Depth = 5.2 miles
• Magnitude 5.4 earthquake, 8/12/98, 07:10:25 PM PDT, located 7 miles SSE of San Juan Bautista, CA. Hypocentral Depth = 5.6 miles

Ship's acoustic signal as it passes by the array.
The classic doppler shifting in frequency over time shows up as the parabolic color bands. The turning point of the parabolic structure is the point at which the ship is at it's closest to the array, after which the doppler shifting lengthens as the ship travels away.
