ATLANTIC CITY - The federal government has moved to dismiss a lawsuit brought by New Jersey environmental officials against a research project that blasts the ocean floor with sound waves, mainly because the project is already finished.
The U.S. Justice Department has asked a federal judge to dismiss the suit brought by the New Jersey Department of Environmental Protection against several defendants, including the National Science Foundation.

Opponents say important procedural issues were not dealt with before the test started.
