A remotely operated underwater vehicle (ROUV) [citation needed] or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general ...
Isopycnal mixing and diapycnal mixing work together to mix and ventilate the entire ocean.

[2] This process is important for ventilating the ocean with oxygen.
