It was suggested later that an offshore earthquake had struck the nearby Grand Banks, dislodging a bank of sediment, which then roared down a channel in the continental shelf and out onto the abyssal plain. Rather than flows of fresh (or at least salty) water, undersea rivers are slurries of silt and sand that cascade along channels on the seabed. “These submarine channel systems are some of the biggest in the Solar System,” says Parsons. It can cost over £25,000 a day to use a research vessel that can launch remotely operated vehicles (ROVs) to explore the deep ocean, so it is hardly surprising few scientists have been able to study these undersea flows. They have roots and are found on the ocean floor. It lies two miles (3.2km) beneath the surface of the Pacific Ocean. 2.1.2 Soil profile. There are multiple dewatering products that can be used to remove sediment from the pumped water, such as dewatering bags. There, the channels tend to be bounded by huge levees that have built up over time. “If you drained all the water away, it would look exactly like a river system with bends and meanders, except there are no trees along the banks,” says Dan Parsons, a sedimentologist at the University of Hull, UK, who travels the world to study undersea rivers .

In a study published in 2010, Peakall and Parsons sent a robotic submarine down to a deep undersea channel that runs across the bottom of the Black Sea.
