A deep-sea mining test 1,300 m down in the South China Sea quickly messed up the seafloor's tiny microbes: genes that turn nitrogen into food for sea life dropped, while signs of low-oxygen conditions rose. Scientists warn even short mining trials can rapidly disrupt the deep ocean's nutrient cycle.

🔬 A new study in the South China Sea reveals deep-sea mining can significantly disrupt microbes essential for nutrient cycling. Samples collected during a 2020 trial at 1,300 meters showed changes in genes related to nitrogen processes and sulfate reduction.

💧 Mining operations stirred up sediment, altering nutrient availability in waters up to 50 meters above the seafloor, particularly impacting nitrogen and silicate levels.

📉 Genes for nitrogen fixation and nitrite reduction decreased, while denitrification genes increased, indicating immediate disruption to the seafloor's microbial ecosystem.
