“We’re creating a permanent record. In a sense, each recording is the equivalent of a specimen in a museum. We’re going to archive these recordings so anybody can have access to ‘em today, or in five years, or in 20 years, and go back and say, ‘You know, what were the sounds like in this forest, in this city, on this island, you know, 15, 20 years ago?’”
The ARBIMON software and its collection of sounds are available to everyone at arbimon.com.
Human-made sound on the high seas may interfere with the ability of sea creatures to use sound effectively for guidance and communication. Researchers recently studied audio recordings made in the Antarctic Weddell Sea. They discovered that a melting iceberg can make a lot of noise, sometimes as much as a magnitude-4 earthquake.
Listen closely to this sound.
Some people might say that is a truck or a stringed instrument like a double bass. But it is an iceberg pushing slowly against the sea floor.
“The iceberg is essentially scraping along and more or less resonating, kind of like a tuning fork.”
That is Robert Dziak of Oregon State University. He led a study of underwater noises around the Antarctic Peninsula, the northernmost part of the southern continent. He and his team of scientists recorded the sounds of an iceberg being born, as it separated from the ice of the mainland.
“We saw it from the beginning, the birth of the iceberg, to its actual eventual death, for lack of a better word.”
