Deep-sea biology: Sisyphus on the bottom of the world.

Small invertebrates living on deep-sea mineral-rich nodules are linked to keeping nodules from being buried by sediment in Earth’s most remote ocean environments.

• Why it matters: Mining interest in deep-sea nodules depends on understanding why these mineral deposits persist on the seafloor rather than being covered by sediment.
• What they did: The study presents new evidence about the role of small invertebrates associated with nodule surfaces, focusing on how they may affect sediment burial.
• The result: The findings suggest a biological mechanism for nodule persistence, implying that these invertebrates could be important for predicting how nodules respond to disturbance.
