The International Seabed Authority is working to set regulations for deep-sea mining as companies engaged in the clean energy transition clamor for more minerals. The seafloor, especially in parts ...
Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains .
Deep sea mining is the extraction of minerals from the seabed of the deep sea. The main ores of commercial interest are polymetallic nodules , which are found at depths of 4–6 km (2.5–3.7 mi) primarily on the abyssal plain .
The two major resources mined at sea include oil and minerals. Over the last 30 years, deep-sea mining has generated between $9 -$11 billion USD in the United States of America. [43] [44] Although this sector seems profitable, it is a high risk, high reward industry with many harmful environmental impacts. [45]
From the Pacific Islands to the Arctic Circle, “In Real Life” goes to the frontlines of the debate over deep sea mining.
Deep sea mining involves removing mineral deposits and metals from the ocean’s seabed. There are three types of such mining: taking deposit-rich polymetallic nodules off the ocean floor, mining ...
Very little is known about deep sea ecosystems or the potential impacts of deep-sea mining. Polymetallic nodule fields are hotspots of abundance and diversity for a highly vulnerable abyssal fauna, much of which lives attached to nodules or in the sediment immediately beneath it.
A part of the Pacific Ocean earmarked for deep-sea mining is home to a surprising variety of life, images from a recent voyage to the Clarion-Clipperton Zone show.
