Ecosystem engineering creates a direct nutritional link between 600-m deep cold-water coral mounds and surface productivity
Cold-water corals (CWCs) form large mounds on the seafloor that are hotspots of biodiversity in the deep sea, but it remains enigmatic how CWCs can thrive in this food-limited environment. Here, we infer from model simulations that the interaction between tidal currents and CWC-formed mounds induces...
