Schematic of the experiment. Water drawn from the ocean is mixed with hyper-saline (or sediment-laden) water prepared on board the vessel, and the mixture is pumped back into the ocean as a plume at depths in the range 25-100m. The evolution and steady-state nature of the plume is monitored using PADs acoustic technology mounted on the fore of the vessel and ROV technology. 24 tons of salt need to be stored on the vessel, and there will be two ~20m3 storage containers as reservoirs for hyper- saline water. The plume hose, ROV umbilical, and PADS will all be in the water between 25-125 m depth at the same time; careful coordination and ship handling will be required.
