Ocean This Week: Deep-Sea Mining Shock, Marine Monument Rollback, Whale Crisis & Vision Breakthrough
AS Marine Conservation & Travel Media 63 subscribers 6 likes 73 views 12 Feb 2026 This week in ocean news: A five-year study in the Clarion-Clipperton Zone in the central Pacific revealed nearly 800 species at a deep-sea mining site — while documenting a 37% decline in animal abundance where mining equipment disturbed the seafloor. The Northeast Canyons and Seamounts Marine National Monument off Cape Cod has been reopened to commercial fishing, removing protections from more than 12,000 square kilometers of deep-sea coral habitat. Researchers in the Southern Ocean are raising alarms over southern right whale reproduction, linking declining calving rates to shrinking Antarctic sea ice and krill shortages. Meanwhile, a simple weighted device is boosting pollack survival rates after catch-and-release from 56% to over 80%, and scientists in the Red Sea have identified a hybrid photoreceptor cell in deep-sea fish larvae that blends rod and cone functions — a discovery that could influence future camera technology and eye research.

How humans are exploiting the oceans | DW Documentary
# How humans are exploiting the oceans | DW Documentary. What would be the consequences of industrial exploitation of the ocean floor? A deep-sea expedition in the Pacific explores this question. Raw materials have been mined on land for thousands of years, often with negative consequences for nature and people. Deep down in the ocean, valuable raw materials are stored en masse: manganese, nickel, cobalt, copper. Many of these materials are currently in great demand. Technically, it is possible to harvest manganese nodules, for example, in the deep sea. They are part of a deep-sea expedition to research the possible effects of harvesting raw materials on the ocean floor. Reporter Michael Stocks and his cameraman spent weeks aboard the ship, on which scientists are monitoring the deployment of a giant underwater harvesting machine on the ocean floor. Humans are dredging the sand from beaches, overfishing fish stocks worldwide - is the seabed now to be industrially exploited as well?

Conservation Tales from the Mariana Trench
A video exploring conservation stories from the Mariana Trench, discussing ocean protection and the impacts of deep sea mining.
The Mariana Trench: Ocean's Deepest Frontier
The Mariana Trench: Ocean's Deepest Frontier AI Labs: Exploratory Science and Paradoxes 5860 subscribers 33 likes 4271 views 9 Mar 2024 Imagine a place so deep that if you dropped Mount Everest into it, the peak would still be over a mile underwater. This is the Mariana Trench, nestled in the Western Pacific, the deepest part of our world's oceans, reaching a staggering depth of over 36,000 feet. The video explores the formation, exploration, biodiversity, and the human impact on this extraordinary underwater landscape. Takeaways 🌍 Formation: The Mariana Trench formed from the collision of the Pacific and Philippine tectonic plates through subduction. 🔍 Exploration: From the first measurements by HMS Challenger to James Cameron's and the DSV Limiting Factor's dives, human exploration has gradually unveiled the trench's mysteries. 🐟 Biodiversity: Despite extreme conditions, life thrives in the trench, including amphipods, snailfish, and unique microbial life. 🚀 Technology: Remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and benthic landers are key to exploring the trench. 🌐 Human Impact: Pollution, including plastics and radioactive debris, threatens the trench's ecosystem, highlighting the need for conservation efforts. 🛢 Deep-Sea Mining: The potential for mining poses risks to the trench's delicate ecosystems, requiring a balance between extraction and conservation. 🔬 Climate Impact: The trench plays a significant role in the Earth's carbon cycle through carbon sequestration, helping to limit global warming. 🧭 Future Exploration: Advances in technology promise further discoveries about the trench's biodiversity, geology, and role in our planet's health. Summary The Mariana Trench's formation is a result of tectonic activities, specifically the subduction of the Pacific Plate beneath the Philippine Plate. Initial explorations, like HMS Challenger's expedition, laid the groundwork for our understanding of the trench. The trench hosts a diverse range of life forms, uniquely adapted to the extreme conditions found at such depths. Cutting-edge technology, including ROVs and AUVs, has been instrumental in exploring the trench's depths and studying its ecosystem. Human activities have introduced pollutants into the trench, threatening its unique ecosystem and highlighting the urgent need for conservation measures. The controversy over deep-sea mining in the trench underscores the ethical dilemma of exploiting deep-sea resources. The Mariana Trench contributes to carbon sequestration, playing a vital role in mitigating climate change. Ongoing and future explorations promise to deepen our understanding of the trench's role in Earth's geological and ecological systems.

Virtual Ocean Dialogues 2020- Communities, Ocean Value, Deep Seabed Mining- Stories from the Pacific
a Conservation Coalition 704 subscribers 2 likes 164 views 19 Jun 2020 This session was hosted as part of the 2020 Virtual Ocean Dialogues by the Deep Sea Conservation Coalition, World Wide Fund for Nature (WWF) and Pacific Network on Globalisation. The ocean is a constant for people of the Pacific, with cultures centred around long-held relationships that remain embedded in everyday life. Knowledge, guardianship and traditional resource management systems enable the bounty of a healthy ocean to perpetually sustain physical, economic and spiritual well-being. The impending industry of deep seabed mining has focused its attention on the Pacific region both on the high seas through the International Seabed Authority and within national jurisdictions, where proposals to date have been shown to be at odds not only with cultural beliefs and practices of Pacific societies, but also with contemporary marine legislation, economic and cultural activities such as fisheries and tourism, and the commitments of all countries to reverse the decline in biodiversity. The outcomes and stories of civil society engagement with prolonged seabed mining licensing processes lay bare the question of appropriateness of the activity in the 21st century. In this Virtual Ocean Dialogue session, stories from frontline indigenous leaders offered a Pacific people’s perspective on the “sustainable relationship” with the life-giving entity, Moana nui. Experts also explored the interconnectedness of deep-sea environments and the rights of both human societies and nature in the context of exploiting the global commons. 1 comments

Stopping Deep Sea Mining: A unique opportunity to avoid ocean catastrophe
atch Canada 647 subscribers 5 likes 202 views 21 Dec 2022 Mining may soon begin in one of the most ecologically fragile and intact places on the planet: the deep seabed. Canadian mining companies are leading the way, putting at risk the health of the deep ocean and the thousands of species who call it home. But the movement calling for an immediate moratorium or ban on deep sea mining is growing fast. How will deep sea mining affect deep sea and marine and coastal ecosystems? What's at stake if this destructive industry goes forward for ocean health and the human communities who depend on that? How can we ensure a global moratorium on deep sea mining is in place before it's too late? Hear from mining-affected communities in the Pacific and global and Canadian organizations on policy, and watch the 16-minute documentary “Blue Peril” — a visual investigation of the impacts of deep sea mining in the Pacific Ocean and how far-reaching these are likely to be.
