Listen to the sounds of the ocean

There's a lot going on under the sea.

For the past year, scientists at Oregon State University, NOAA and the federal Energy Department have been listening to the sounds picked up by a microphone in the Pacific Ocean, off the coast of Oregon.

Researchers say they've picked up a "symphony" of noise -- some natural, some man-made.

While the sounds are fascinating, man-made ocean noise has been an area of concern among researchers some time.

According to NOAA, sound waves travel well in water, and that can have a detrimental effect on whales and dolphins who use their hearing to navigate through the dark ocean.

Here's a sample of some of the sounds researchers have picked up.
