Keeping the Noise Down Under the Sea

Posted on May 24, 2023 by Navarre Bartz

A pinwheel sits in an aquarium to simulate an offshore wind turbine. Bubbles come up from the "seabed" to encircle it to demonstrate a bubble curtain with an image of a sound waveform overlaid with the video to show the sound confined to the area within the bubble curtain.

Since sound is the primary sense used by most ocean life, disruptions to the natural noise levels in the ocean from human activities can be particularly problematic for marine life. …read more Continue reading Keeping the Noise Down Under the Sea→
