The Japan Trench, a vast tectonic chasm along the Pacific Ring of Fire, is known for its extreme depth—stretching 5 miles ...

New scans of the bottom of the Japan Trench reveal extensive burrow structures and evidence of regular "reset" events that ...

Traces of organisms detected in sediments from 7.5 kilometers below the ocean surface reveal how organisms living in the deep sea are engineering their own environments. Analyses of sediment cores ...

Organisms in the deep sea rely on gravity flows to lay down sediment and then make burrows beneath the seafloor, according to a new study.

I recently participated in a three-week-long, National Science Foundation-funded research cruise to the Mariana Trench. Our ...

The deepest parts of the ocean remain one of the most mysterious frontiers on Earth, hiding creatures that defy expectations.

Scientists reached the bottom of the Red Sea and what they found was startling. If you thought we had collectively searched most of the sea as a human race, you’d be wrong. In fact, only five percent ...

The deepest regions of Earth's oceans, known as the abyssal and hadal zones, lie at least as far under the water's surface as Mount Rainier's peak rises above the land surface. These great depths of 4 ...

Understanding the trench’s biodiversity is essential not only for studying deep-sea ecosystems but also for grasping its role in regulating the Earth’s climate system. Kolbusz noted that the ...
