Deep sea

NOAA researchers with the Okeanos Explorer expedition recently captured a video of a glowing shrimp with some crazy antennae.

It’s not silent at the bottom of ocean. For three weeks, researchers from Oregon State University dropped a titanium-encased hydrophone at the bottom of the Mariana Trench in the Pacific, at a depth of 36,000, deeper than Mount Everest is tall.

A deep-sea exploration crew was totally surprised to see a rare sperm whale during their expedition.

Ten years on from the devastating Boxing Day earthquake and tsunami, our understanding of very large earthquakes has grown enormously. From satellites monitoring changes on the Earth’s surface to drilling deep below the ocean floor, new techniques are constantly being developed to help us figure out why earthquakes are sometimes so big, and so deadly.

The DeepFlight Challenger submarine will journey to the deepest known part of the ocean, the Challenger Deep at the southern end of the Marianas Trench.
