An international team of scientists has documented nearly 800 species, many previously unknown, living nearly 4,000 meters below the Pacific Ocean's surface. Their five-year study in the Clarion-Clipperton Zone also tested the environmental impacts of deep-sea mining, finding significant local reductions in animal numbers and diversity. The findings, published in Nature Ecology and Evolution, provide crucial data for regulating future extraction of critical metals.

Scientists at Tokyo Metropolitan University have identified polymer-coated fertilizers as a significant source of ocean microplastics, with pathways from farmland directly influencing how much reaches shorelines. Their study reveals that direct drainage from fields to the sea results in far higher beach accumulation than river transport. This work sheds light on the elusive fate of plastics in marine environments.
