What's Inside
What Exactly Is Deep-Sea Rare Earth Mining?
Deep-sea rare earth mining is an emerging industry that focuses on extracting valuable rare earth elements (REEs) from the ocean floor. This process involves locating, extracting, and processing mineral-rich deposits found in deep-sea environments, typically at depths of 1,000 to 6,000 meters.
- Unlike traditional land-based mining, deep-sea mining operates in a unique and challenging environment.
- The ocean floor contains significant deposits of REEs, often in higher concentrations than terrestrial sources.
- Deep-sea mining offers potential access to previously untapped resources.
“The deep sea is often described as the last frontier on Earth, and now we’re looking to exploit its resources in ways we never have before.” – Dr. Helen Scales, marine biologist and author
Types of Rare Earth Elements Found in the Ocean
- Light Rare Earth Elements (LREEs): Lanthanum, Cerium, Praseodymium, Neodymium
- Heavy Rare Earth Elements (HREEs): Europium, Terbium, Dysprosium, Yttrium
These elements are crucial components in various high-tech applications, including:

The primary environmental concerns include the destruction of unique deep-sea habitats, potential extinction of undiscovered species, sediment plumes that can smother marine life, noise pollution affecting marine mammals, and the release of toxic materials into the water column.
How do rare earth elements extracted from the ocean compare to those mined on land?
Rare earth elements found in deep-sea deposits are often more concentrated and easier to extract than those in land-based mines. They also tend to have fewer radioactive elements associated with them, which can make processing safer and more environmentally friendly.
What international laws govern deep-sea rare earth mining?
The United Nations Convention on the Law of the Sea (UNCLOS) and the International Seabed Authority (ISA) are the primary governing bodies for deep-sea mining activities in international waters.
