Researchers have identified natural barrier zones on an underwater fault that act as brakes to stop earthquakes from growing larger. The findings come from detailed studies of the Gofar transform fault off Ecuador.

Researchers have identified a mysterious golden orb discovered more than two miles underwater in the Gulf of Alaska as the remains of a giant deep-sea anemone. The object, collected during a 2023 NOAA expedition, puzzled experts for over two years until advanced DNA analysis provided the answer. The finding highlights the ongoing mysteries of deep-ocean life.
Researchers have discovered that continents are slowly stripped from below by mantle waves, feeding volcanic activity in distant oceans. This process explains continental chemical signatures in remote ocean islands. The findings, published in Nature Geoscience, challenge traditional views on mantle dynamics.

A new study reveals that sediment plumes from deep-sea mining could starve vital marine life in the ocean's twilight zone by replacing nutritious particles with nutrient-poor waste. Researchers from the University of Hawai'i at Mānoa found that this 'junk food' effect threatens zooplankton and micronekton, potentially rippling through the entire ocean food chain. The findings, based on a 2022 mining test in the Clarion-Clipperton Zone, highlight risks to ecosystems supporting global fisheries and carbon cycles.
