Activities take place mainly in the claim area, covering 75,000 square km in the eastern part of the Clarion-Clipperton Fracture Zone in the Pacific Ocean and are determined by such international regulations as United Nations Convention on the Law of the Sea (UNCLOS), and Regulations on Prospecting and Exploration for Polymetallic Nodules in the Area approved by the International Seabed Authority on 13 July 2000 (ISBA/6/A/18). According to provisions of the 15-year contract for exploration, signed 29 Mar 2001 with the International Seabed Authority, current exploration of IOM aims to obtain geological data and information of nodule deposits and reserves within the claim area, as well as to collect data on physical, chemical, geological and biological components of marine environment required to establish environmental baseline in the exploration area against which to assess and prevent harmful effects of its activities. Takes part in the international 'Benthic Impact Experiment (BIE)' to study the impact of a simulated mining operation. Programme of activities also included research on development of a conceptual design for a future mining system and work on the optimization of existing technological schemes for extraction valuable components from polymetallic nodules, and development of the basic technological schemes for polymetallic nodules processing in the future. Arranges international conferences, workshops and symposia.
