For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but ...

Study identifies a combination of factors that support and maintain the health of marine ecosystems via the churning of the seafloor by invertebrate animals.

Deep below the surface of the ocean, bacteria and critters that feed off nutrients spouting from hydrothermal vents met with ...

Our expedition’s drilling of the seafloor revealed a massive but previously unknown volcanic eruption that took place more than 500,000 years ago.

Analysis of seafloor sediment cores taken from Beppu Bay (70m deep) revealed microplastic deposits (MP) increasing from 1960 through 2015. The amount of phytoplankton showed a similar trend ...

To be sure, although the sediment in which the cells were trapped was up to 100 million years old, the age of individual cells remains uncertain.

This decomposition process appears to have lasted for a period of 40,000 years, ultimately warming the planet by more than 5 degrees Celsius. Sediments far below the seafloor hold evidence of the ...

Mapping the seafloor sediment superhighway Study identifies a combination of factors that support and maintain the health of marine ecosystems via the churning of the seafloor by invertebrate animals.

Even after 100 million years buried in the seafloor, some microbes can wake up. And they’re hungry. An analysis of seafloor sediments dating from 13 million to nearly 102 million years ago found ...

According to a recent paper published by MBARI geologists and their colleagues, methane gas bubbling through seafloor sediments has created hundreds of low hills on the floor of the Arctic Ocean ...

In a new paper published in Nature Communications, the researchers describe how they gathered samples from deep below the seafloor where sediments settled and hardened over tens of millions of years.

The PEAT expeditions are recovering a series of continuous historical records in sediments at a number of different geographic locations beneath the equatorial Pacific Ocean. The first research ...
