Antonella wants answers as to why these whales are becoming fatally stranded and will not stop until she finds them. Military sonars are built to detect hostile submarines over hundreds of miles, but that needs hugely destructive sound volumes. As the threat of energy-wars increase, scientists are standing up to tackle the consequences for the oceans.
