Ecosystems

Researchers at the Woods Hole Oceanographic Institution have identified mid-sized fish, such as the bigscale pomfret, as key connectors between deep and surface ocean ecosystems. These fish perform daily migrations in the twilight zone, influencing the behavior of large predators like sharks. The findings, based on satellite tracking, reveal how environmental factors like water clarity affect their movements.

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.
