Who uses SOFAR?
Many scientists think that humpback whales use the SOFAR Channel to communicate across these vast distances. What is the SOFAR Channel? It’s a layer of water deep in the ocean (near Bermuda it’s around 1000 m deep) where the speed of sound is at a minimum.
Why is deep sound channel important?
It is important to understand that the way sound travels is very much dependent on the conditions of the ocean. The sound speed minimum at roughly 1000 meter depth in mid-latitudes creates a sound channel that lets sound travel long distances in the ocean.

Where is the SOFAR channel?
the oceans
SOFAR channel, in full sound fixing and ranging channel, zone of minimum sound speed in the oceans that occurs at depths of approximately 1,000 metres (3,300 feet).
What is SOFAR used for?
SOFAR is an ocean “channel” that allows sound to carry great distances. At the height of World War II, scientists tested a theory that low-frequency sound could travel long distances in the deep ocean. They deployed a hydrophone from their research vessel, which was anchored off of Woods Hole, Massachusetts.
Why do Thermoclines exist?
A Thermocline is formed by the effect of the sun, which heats the surface of the water and keeps the upper parts of the ocean or water in a lake, warm. Water near the bottom remains colder as sunlight doesn’t penetrate enough.
How do sound channels work?
Overview. A channel is a representation of sound coming from or going to a single point. A single microphone can produce one channel of audio, and a single speaker can accept one channel of audio, for example. A digital audio file can contain multiple channels of data.
Do SOFAR hosts get paid?
All the volunteers who actually put on the shows aren’t paid, and neither are the venue hosts, though at least Sofar pays for insurance. The startup has previously declined to pay first-time Sofar performers, instead providing them a “high-quality” video recording of their gig.
What is a SOFAR used for?
Do whales use the SOFAR channel?
Baleen whales appear to take advantage of this SOFAR channel to broadcast songs for great distances.
Is sound faster in air or water?
water
While sound moves at a much faster speed in the water than in air , the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.
How do SOFAR spheres work?
The sofar spheres were hollow, heavier than an equal volume of water (so they sank), and strong enough to hold off water pressure until they reached the depth of the sound channel. At that depth the sphere suddenly collapsed, and sent out a pulse of sound that could be heard thousands of kilometers away.
