In what is now Norway, fisher-farmers once caught massive bluefin tuna along the world’s second-longest coastline. Over centuries, Norwegians developed fishing techniques and became adept navigators of the sea. In the 1960s, annual herring catches that had peaked at 600,000 tons abruptly vanished following overfishing practices enabled by new technology. The herring population then took nearly two decades to recover.
On January 9, 2024, the Norwegian parliament voted to allow exploration for minerals such as copper and cobalt from the seafloor. The vote aims to position Norway as the first country to commercially mine the ocean floor. Deep-sea mining differs from fisheries because it does not depend on maintaining stable fish populations. The activity is described as posing a significant threat to marine ecosystems before scientists fully understand the life forms involved.
Remote mining of volcanic seabed and hydrothermal vent areas
Norway’s approach is described as more extreme than mining plans in other regions. While other areas focus on harvesting polymetallic nodules, Norway intends to mine its volcanic seabed. The plan involves using remote-controlled machines to dismantle hydrothermal vents and strip mineral crusts from seamounts. The method is expected to affect complex ecosystems that include anemones, sponges, and ancient corals.
Deep-sea ecosystems are characterized by slow development. Some corals can live for up to 3,000 years, according to the source facts. Damage from mining could therefore take centuries or longer to recover. The deep sea is also described as largely unexplored, with many species yet to be discovered.
Limited knowledge of deep-sea habitats and baseline surveys
The source notes that research in the deep sea is challenging and that scientists often struggle to understand how these ecosystems function. It also points to recent declines in Norwegian marine life linked to overfishing and pollution. In the Oslofjord, more than 80% of cod populations have vanished.
Although coastal ecosystems can recover relatively quickly, deep-sea impacts are described as potentially more long-lasting due to slow regeneration rates. Norway’s exploration process includes environmental baseline surveys. However, the source states these surveys are likely to cover only areas with attractive mineral deposits, leaving large regions unstudied. Without comprehensive data, regulatory measures would be speculative.
Technology-driven resource use and an alternative involving urban materials
The source describes a historical connection between Norwegians and the sea alongside a track record of using technology to exploit natural resources. It also notes that such exploitation has often caused ecological harm while creating opportunities for protective measures and sustainable practices. As an alternative to deep-sea mining, it cites urban mining that recovers valuable minerals from existing infrastructures.
The material frames Norway’s decision as a balance between technological advancement and ecological preservation. It also states that future outcomes may depend on approaches that prioritize sustainability over extraction. The article ends after these source facts are exhausted.
