As part of their regulatory obligations, US-based The Metals Company (TMC) subsidiaries, Nauru Ocean Resources Inc (NORI) and Tonga Offshore Mining Ltd (TOML), have submitted their datasets to the International Seabed Authority’s DeepData. This covers a decade of exploration in the Clarion Clipperton Zone of the Pacific Ocean. This data builds on two previous submissions.

The company claims that the data reflects the most comprehensive environmental dataset ever assembled for deep-sea minerals development and shows that seabed extraction is safe for the environment.

The data will be made publicly available through open repositories including DeepData and UNESCO’s Ocean Biodiversity Information System (OBIS).

In January, TMC submitted an application for commercial metals recovery from the seabed. It says it expects the final granting of the commercial recovery permit within the next 12 months.
