American Ocean Minerals Corporation has completed one of the most extensive environmental baseline research campaigns conducted in the deep-sea minerals sector, generating critical data to support resource development, environmental assessment and future regulatory approvals in the Cook Islands.
American Ocean Minerals Corporation (AOMC) has successfully completed Expedition 7, a three-week offshore research campaign designed to strengthen the environmental baseline data required to support future deep-sea mineral development in the Cook Islands.
Conducted aboard the company’s dedicated research vessel, MV Anuanua Moana, the expedition completed 53 sampling sites and collected more than 4,000 physical samples. The campaign is believed to be one of the most productive benthic environmental baseline studies undertaken within the deep-sea mining sector to date.
Building the Scientific Foundation for Deep-Sea Resource Development
The programme forms part of the environmental and technical workstreams supporting the advancement of polymetallic nodule resources within Moana Minerals’ EL3 exploration licence area.
Sampling activities included sediment chemistry, macrofauna, meiofauna, foraminifera and environmental DNA (eDNA) analysis, providing critical information on ecosystem conditions and natural variability across the project area. Additional datasets covering bathymetry, water-column biomass and marine observations were also collected.
The results are expected to support ongoing environmental impact assessment work and future engagement with Cook Islands regulators as the project progresses toward key development milestones.
Dedicated Research Vessel Strengthens Project Execution
According to AOMC Chairman Tom Albanese, the campaign highlights the strategic value of maintaining a dedicated research platform capable of supporting environmental science and resource definition activities simultaneously.
The MV Anuanua Moana enables recurring data collection without the scheduling constraints typically associated with chartered vessels, while supporting multiple offshore work programmes from a single platform.
“Responsible development requires environmental science and resource assessment to advance in parallel,” Albanese said. “The successful completion of this campaign reinforces the strategic value of the Anuanua Moana and our ability to collect consistent, high-quality data while advancing the regulatory work required to evaluate these resources responsibly.”
Supporting Resource Definition and Regulatory Readiness
As deep-sea mineral projects move from exploration toward potential development, comprehensive environmental baseline studies are becoming an increasingly important component of project planning and regulatory approval processes.
Hans Smit, CEO of Ocean Minerals, said the integrated sampling programme has significantly expanded understanding of deep-sea ecosystems within the Moana 1 Project Area.
“The combination of biological, chemical, physical and geological sampling is exactly the kind of integrated science required to assess natural variability, understand ecosystem structure and support evidence-based environmental management,” he said.
