Treasure islands in the Pacific - From Hawaii to the Cook Islands (1/2) | DW Documentary

Key Concepts

• Pacific Ocean exploration
• Military exercises in the Pacific (e.g., German Air Force participation in US-led maneuvers)
• Ocean acidification and its impact on marine life (specifically corals)
• Deep-sea mining of polymetallic nodules and associated environmental concerns
• Economic development of Pacific Island nations (e.g., Cook Islands)
• Whale research and conservation efforts
• Remote island life and challenges (e.g., Chatham Islands)

Hawaii: Military Presence and Ocean Acidification

The journey begins in Hawaii, the youngest US state, amidst a large-scale military exercise involving 40 warships, submarines, and over 150 aircraft from 29 nations, led by the USS Carl Vinson. The narrator's team, flying in a single-engine propeller plane, coordinated with air traffic control to avoid dangerous encounters with German Air Force Eurofighters participating in the exercise. General Ingo Gerhartz, head of the German Air Force, highlights the strategic importance of the Indo-Pacific region to European security and economic interests, justifying the long-distance deployment. The German Eurofighters flew 1.3 million kilometers and set a world record for the longest Eurofighter flight ever (10 hours and 31 minutes from Japan to Hawaii). US Coast Guard and German Navy units were also practicing port security and mine-diving operations, respectively, facing challenges like hammerhead sharks.

At Coconut Island, part of the University of Hawaii, Lucie Knor is researching ocean acidification. She explains that about a third of the CO2 released into the atmosphere has been absorbed by the ocean, altering its chemistry. Her research shows a direct correlation between rising atmospheric CO2 levels and increasing CO2 levels in the ocean, leading to a decrease in pH (increased acidity). This acidification poses a significant threat to shell-forming organisms like corals, as acid dissolves calcium carbonate. Scientists on Coconut Island are breeding corals that can survive in these changing conditions.

Cook Islands: Deep-Sea Mining and Whale Conservation

After Hawaii, the team heads to the Cook Islands, celebrating their 59th anniversary of autonomy from New Zealand. Emile Kairua, head of the Ministry of Cultural Development, discusses the positive influence of Christian missionaries in ending cannibalism and tribal warfare. The Cook Islands are exploring deep-sea mining for polymetallic nodules, a potential source of significant revenue.

Hans Smit, CEO of MOANA Minerals, holds a license to explore an area roughly the size of El Salvador for these nodules, which contain manganese, copper, nickel, rare earths, and cobalt. He uses a deep-sea underwater robot (ROV) to explore the seabed at depths of over 5,000 meters. Smit argues that deep-sea mining research is necessary to understand the potential environmental impact and make informed decisions, countering the moratorium calls from countries and companies like BMW and Google. He emphasizes the need for objective decision-making based on scientific data rather than misinformation and emotion.

Prime Minister Mark Brown supports deep-sea mining, believing the Cook Islands could meet global demand for critical metals for centuries. He notes the World Bank's projection of a 400-500% increase in cobalt demand by 2030. The Cook Islands possess an estimated 500 million tons of nodules in the explored area, valued at hundreds of billions of US dollars. Brown also mentions China's increasing presence in the Pacific region as a substantial partner in infrastructure investment. Emile Kairua defends the Cook Islands' right to make sovereign decisions regarding their resources, rejecting outside interference reminiscent of the colonial era.

Nan Hauser, a renowned whale researcher known as the "Whale Lady," studies humpback whales in the Cook Islands. She and her volunteers collect GPS data, fin photos, and skin samples to map migration routes and protect whales from fishing nets and whaling activities. Hauser notes that the Nukpai tree's blossoming traditionally signaled the arrival of whales, but the timing has shifted later in the year, possibly due to rising water temperatures. She recounts an experience where a whale protected her from a tiger shark, highlighting the altruistic behavior of whales. Mia, a volunteer, dives with the whales to collect skin samples for DNA analysis. In 2024, Tonga, New Zealand, French Polynesia, and the Cook Islands signed a treaty granting whales and dolphins personal rights.

Chatham Islands: Remote Island Life

The team then travels to the Chatham Islands, 800 kilometers off the coast of New Zealand, characterized by a cool climate and strong storms. The island faces challenges due to a broken-down cargo ship, leading to shortages of essential goods. Jade Dixon, an abalone diver, collects sea snails at a depth of 10-15 meters, facing the risk of great white sharks.

Conclusion

The journey through the Pacific reveals a complex region facing diverse challenges and opportunities. From military exercises and ocean acidification to deep-sea mining and whale conservation, the Pacific Islands are at the forefront of global issues. The video highlights the tension between economic development and environmental protection, the importance of scientific research in informing policy decisions, and the resilience and cultural richness of the Pacific Island communities. The journey underscores the interconnectedness of the world and the need for international cooperation to address the challenges facing this vast and vital ocean region.
