Mar Del Plata – Argentina’s navy says a noise detected in an undersea area on Monday did not come from a submarine that has been missing since last week with 44 sailors on board.

Navy spokesman Enrique Balbi says the “noise” was analyzed and experts determined it did not come from tools being banged against the hull of a submarine as was previously reported by some media. He says it likely came from a “biological” source.

The noise was heard in the South Atlantic about 220 miles (360 kilometers) from the Argentine coast and at a depth of about 650 feet (200 meters).
