The Legal and Technical Commission of the International Seabed Authority (ISA) finalized on 20 July 2021 the selection of candidates for two environmental at-sea training opportunities provided by Tonga Offshore Mining Limited (TOML) in accordance with its obligations under its exploration contracts for polymetallic nodules with ISA.

The two selected candidates are:

  • Ms. Mariana Cullell Delgado from Costa Rica
  • Mr. Kilrick Pelobule from Solomon Islands

Ms. Delgado and Mr. Pelobule will take part in an offshore pelagic environmental campaign being organized collaboratively by TOML and Nauru Ocean Resources Inc (NORI) in September-October 2021 in NORI’s contract area in the Clarion Clipperton Zone, for a duration of approximately six weeks.



All contractors with ISA have a legal obligation to provide and fund practical training opportunities for personnel from developing States and those of ISA, including the participation of such personnel in all activities in the Area which are covered by the contract.

The legal basis for the requirement stems from the provisions of UNCLOS and the 1994 Agreement and is set out in the standard terms of exploration contracts signed with ISA.
