Where to find Manganese Nodule
Clarion-Clipperton Zone (CCZ)
A vast abyssal plain in the Pacific Ocean, between Hawaii and Mexico, known for the highest concentrations and metal grades of manganese nodules globally.
Peru Basin
Located in the southeastern Pacific Ocean, another significant area for manganese nodule occurrences.
Indian Ocean
Parts of the central and eastern Indian Ocean also host extensive manganese nodule fields.
Atlantic Ocean
Less abundant than in the Pacific and Indian Oceans, but some nodule fields exist, particularly in the North Atlantic.
Collecting tips
- Deep-Sea Environment. Manganese nodules are exclusively found in deep-sea environments, typically at depths of 4,000 to 6,000 meters. They are not found on land or in shallow waters.
- Sampling Methods. Collection requires specialized deep-sea sampling equipment such as box corers, grab samplers, or remotely operated vehicles (ROVs) and submersibles.
- Associated Sediments. They are typically found lying on or partially buried in fine-grained abyssal clays (red clays) or siliceous oozes.
