The video tutorial explains the process of seabed mining, where companies seek licenses to extract minerals like copper and gold from the ocean floor. Remotely-operated vehicles are deployed to the seabed to install sonobuoys and guide mining machines. These machines, including a bulk cutter, auxiliary cutter, and collecting machine, are lowered to the seabed to extract and process minerals. The machines send data back to operators, and the collected slurry is pumped to the surface for further processing and transport to shore for refining.

What is the primary purpose of sending remotely-operated vehicles to the seafloor?

• To measure water temperature

• To conduct surveys and install sonobuoys

• To collect fish samples

• To photograph marine life

Which machine is responsible for harvesting steep and uneven areas on the seafloor?

• Sonobuoy

• Bulk cutter

• Collecting machine

• Auxiliary cutter

How are the machines on the seafloor connected to the surface?

• Via wireless signals

• Using steel cables

• Through satellite communication

• By fiber optic cables

What happens to the rock slurry once it reaches the ship?

• It is immediately refined on the ship

• It is discarded back into the sea

• It is used as fuel

• It is filtered, dried, and loaded onto a barge

What parameters are measured by sensors in the machines?

• Salinity, pH, and turbidity

• Speed, altitude, and direction

• Color, taste, and smell

• Temperature, pressure, density, and vibration
