Alborosie

Answer:

Deep ocean exploration is all about investigating its geology i.e physical and chemical along with biological conditions on the ocean floor where sunlight cannot reach. There has been an interest in the deep ocean due to scientific communities and for industrial purpose. Exploration is carried by submarine and remotely operated vehicles at about 300m to 1000m. Analysis of ocean floor had found a huge concentration of mineral deposits such as manganese, copper, cobalt, gold, zinc etc.

The mining is carried out by using hydraulic pumping or bucket type excavator and are processed on ground industries. Deep-ocean mining has not been able to reach its full potential due to the high cost of operating and environmental damage.
