"MIAMI — The government divers who plunged into the bay near the Port of Miami surfaced with bad news again and again: Large numbers of corals were either dead or dying, suffocated by sediment.

The source of the sediment, environmentalists say, is a $205 million dredging project, scheduled to end in July and intended to expand a shipping channel to make room for a new generation of supersize cargo ships.

The damage to the fragile corals was never supposed to have happened. In 2013, federal agencies created a plan to protect the animals from the churn of sand and rock by placing them at a distance from the dredge site. It was a strategy intended to balance Miami’s economic interests with the concerns of environmentalists, who worry about the rapid deterioration of reefs across South Florida."
