Scientists have identified a newly recognized threat lurking beneath the ocean’s surface: sudden episodes of underwater darkness that can last days or even months. Caused by storms, sediment runoff, algae blooms, and murky water, these “marine darkwaves” dramatically reduce light reaching the seafloor, putting kelp forests, seagrass, and other light-dependent life at risk.
The world has started to recognize that the climate’s fate depends on what happens to the ocean. At COP30, ocean-based solutions attracted significant attention and investment, but much more must be done to...

Scientists have uncovered why big predators like sharks spend so much time in the ocean’s twilight zone. The answer lies with mid-sized fish such as the bigscale pomfret, which live deep during the day and rise at night to feed, linking deep and surface food webs. Using satellite tags, researchers tracked these hard-to-study fish for the first time. Their movements shift with water clarity, potentially altering entire ocean food chains.
