Sixteen beaked and minke whales were found stranded on beaches in the Bahamas shortly after US Navy ships using the high-intensity sonar had passed by. Six are known to have died, and the rest were pushed back into the sea. But a fall in sightings of beaked whales has led researchers working in the area to believe that many more may have died.
