A recent deep-sea expedition into the Tonga Trench in the Pacific Ocean led to an astonishing discovery: a massive Pacific Sleeper Shark was filmed at an astounding 1,400 meters below the surface.

Scientists discovered the 1-foot-long animal while aboard a submersible several miles deep in the Pacific Ocean. Take a look.

the deepest trench on Earth. The Challenger Deep plunges to an estimated 10,935 metres (roughly 6.8 miles) below sea level - more than 1.2 miles farther from sea level than the peak of Mount Everest.

These processes enhance the retention of organic carbon, making hadal trenches important sites for carbon burial in the deep sea. The variability in organic carbon deposition rates across ...

Hadal trenches are utterly dark ... Captain Buckle set a course for the Challenger Deep, more than 200 miles out to sea. But when the ship arrived above the dive spot, the expected clearing ...

The year 2023 brought major breakthroughs in the research journey of the Integrated Deep Ocean Observing System (IDOOS) Expedition, and their work took them to this remote trench. Scientists aboard ...

The Mariana Trench is the deepest place on Earth, and we're still in the dark about much of the life that calls it home. Here are just a few of the trench's eye-popping residents.

However, at the time only about 10% of Earth's seafloor had been mapped to high resolution, so this figure is only an estimate. Challenger Deep, in the Mariana Trench, is the deepest point in the ...
