Submarine Rivers of Sediment
Turbidity currents move suspended sediment into the ocean. In general, the more sediment, the stronger the turbidity current, but one process may generate turbidity currents from very dilute rivers.

How Are Microplastics Transported to Polar Regions?
New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.

Volcanic Eruption Creates Temporary Islands of Pumice
Rafts of pumice, spewed from an undersea volcano, recently appeared in the South Pacific. These transient, movable islands are important toeholds for marine life like barnacles, coral, and macroalgae.
