CORVALLIS, Ore. – A sound in the Mariana Trench notable for its complexity and wide frequency range likely represents the discovery of a new baleen whale call, according to the Oregon State University researchers who recorded and analyzed it.

Scientists at OSU’s Hatfield Marine Science Center named it the “Western Pacific Biotwang.”

Lasting between 2.5 and 3.5 seconds, the five-part call includes deep moans at frequencies as low as 38 hertz and a metallic finale that pushes as high as 8,000 hertz.

“It’s very distinct, with all these crazy parts,” said Sharon Nieukirk, senior faculty research assistant in marine bioacoustics at Oregon State. “The low-frequency moaning part is typical of baleen whales, and it’s that kind of twangy sound that makes it really unique. We don’t find many new baleen whale calls.”

It was thought that this call was only made during mating, which is done during winter. But for some reason this call has been heard throughout the entire year.

Here is a direct link to the recording.

Although it is "believed" the sound is being made by minke whale/s, the smallest of the baleen whales, it has not been corroborated.

If this is the call of Minke whales why is it that they changed their call and can now be heard throughout the entire year? Are these whales reacting to changes occurring deep in the ocean floor such as the increased underwater warming? Are these whales reacting to other changes occurring in the Earth's crust?

It could also be that we just didn't know as much about them as we thought.

I dated a lot of whales in my time, never hooked up with a baleen though. Hey any "fold" in a storm man.

I looked at the other thread. It seems to encompass more.
