Cook Islands-led science strengthens deep-sea habitat understanding

Cook Islands scientists have completed a major review of more than 11,000 deep-sea observations, working with research partners in Hawai‘i to improve how seabed habitats are classified and analysed for future environmental management.

The work was advanced during meetings at the Deep-sea Animal Research Centre at the University of Hawai‘i at Mānoa in September 2026, where Seabed Minerals Authority (SBMA) Knowledge Management staff Chloe-Ane Wragg and Dr John Parianos presented a revised Cook Islands approach to classifying deep-sea substrates and geological features.

Cook Islands–U.S. science partnership delivers new maps, samples and deep-ocean knowledge

More than 52,000 square kilometres of seafloor mapping, almost 500 scientific samples and extensive deep-sea imagery collected during the 2026 Cook Islands ROV Exploration are now supporting continuing research involving Cook Islands scientists and international partners.

EX2605, the 26-day expedition aboard NOAA Ship Okeanos Explorer from 19 July to 13 August 2026, was a partnership between the Seabed Minerals Authority (SBMA), NOAA Ocean Exploration and scientific partners. Cook Islands scientists contributed directly to ROV operations, mapping, sample collection and processing, and science planning.

For SBMA, the value of the expedition did not end when the vessel left Cook Islands waters.

Cook Islanders strengthen knowledge and capability in deep-sea resource management

Twenty-three Cook Islanders have returned from China with new knowledge and perspectives on deep-sea resource management after a 10-day training programme designed to strengthen local knowledge and capacity in this area.

The China–Cook Islands Training Programme on Deep-Sea Resource Management took place in Hangzhou and Changsha from 24 August to 2 September 2026.

The programme brought together Cook Islanders from different backgrounds, including government officials, professionals, and students from local colleges and universities in New Zealand. Participants also represented communities from both the Northern and Southern Group islands.

New camera technology shows the Cook Islands seabed in unparalleled detail

The first dive of the NA176 marine scientific cruise has delivered exceptional results.

One of the cruise participants, Deep Sea Power and Light, provided cutting edge new camera technology [1] and a small team of experts to commission and maintain the equipment. This is the first time this technology has been deployed to such depths anywhere in the world.

Cook Islands Welcomes E/V Nautilus for 21-Day Deep-Sea Science Research Cruise

Later this week, the Cook Islands will welcome the arrival of the exploration vessel E/V Nautilus, a world-class platform for deep-sea discovery. Over the course of a 21-day science mission beginning 1 October 2025, the Seabed Minerals Authority (SBMA) and its partners will work alongside the Nautilus team to explore and better understand the hidden depths of Marae Moana.

All creatures great and small—life in the abyss

Life is everywhere. It is found in rocks deep beneath the surface of the earth, in a lake buried under the ice in Antarctica, and even in ponds of liquid tar-asphalt. So, although the physical environment-in the 5,000 m deep ocean floor is challenging, numerous species of organisms call it home.

Cook Islands deep sea mining poll sparks controversy

An online opinion poll on deep sea mining has been criticised by the government regulator responsible for overseeing seabed minerals activities in the Cook Islands as “fundamentally flawed”.

Rima Browne Explores the US Leadership Programme on behalf of the Cook Islands 

In a bid to bolster sustainable development and explore collaboration opportunities, representatives from the Cook Islands have actively participated in a recent International Visitor Leadership Programme (IVLP) focused on "Sustainability and Economic Development in the Blue Economy."
