> Because this loose rubble is in constant motion, tumbling and rolling around, coral larvae don’t have enough time to grow before they get squashed.

The people running the MARS program did this using Reef Stars, hexagonal steel structures coated with sand. “These structures are connected into networks and pinned to the seabed to reduce the movement of the rubble,” Lamont said.
