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.

A breakthrough discovery of oxygen production in darkness could redefine life's origins on Earth and open new frontiers in space exploration.

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 ...

While on a shark research expedition off the coast of Tenerife, marine biologists said they captured the first images of a live adult black seadevil anglerfish near the ocean’s surface.

with the aim of confirming nodule-driven oxygen production in the deep ocean with fresh data. Once again, the landers will seal off samples of water and sediment from the sea floor to measure ...

The most powerful neutrino on record, with help from a deep-sea sensor, has provided the first evidence for high-energy ...
