Little is known about the ecosystems in these environments and even less about bioturbation (the reworking of seafloor sediments by inhabiting organisms), which is a key process that affects ...

On the abyssal plains, at depths between 3,000 and 6,000 meters, polymetallic nodules are scattered across millions of square ...

Marine sediments are extremely diverse and cover the majority of the Earth's surface. By stirring up and churning the ...

They used the Shinkai 6500 manned research submersible and equipment that can dive to great depths to sample seafloor sediments at seven locations in 2019. The sites were around 1,000 meters deep ...

Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are ...

We examined nitrogen cycling over a 1-yr period in shallow, sandy sediments at two contrasting sites near a barrier island in the northeastern Gulf of Mexico, and we provide here the direct ...

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.
