If you’ve ever made a trans-Atlantic call—or, heck, used the internet—then you might like to know a few things about the ocean floor. Mighty but enigmatic underwater rivers flow along the ...

C olumbia University’s research ship Vema steamed back into New York Harbor last week with new information about the “rivers” that flow on the bottom of the ocean. About 600 miles east of ...

At the same time, particles are worn down from rocks and end up in rivers. As with plants, some carbon is released back into the atmosphere, but some eventually accumulates at the bottom of the ocean.

Immense rivers that dwarf the Thames have been found at the bottom of the ocean by British scientists. Like those on land, the submarine waterways carve out channels, tributaries, flood plains ...

Fresh water from rivers filled with sediment can also be denser than sea water, and so plunge to the bottom of the ocean.” It now seems that something strange happens to the flows as they go ...

There are also hydrothermal fluids, which come from openings at the bottom of the ocean, NOAA says. Ocean water heats up from magma at the Earth’s core when it seeps into cracks in the seafloor.

Yet mapping alone can only tell us so much about what's going on at the bottom of the ocean floor, Ferrini said, adding it can miss things like what the seafloor is made up of or what's living ...

When denser river water flows into the ocean, it creeps along the bottom churning up sediments to create a turbidity current. For the first time, researchers caught a flood-triggered hyperpycnal ...
