Sperm Whales - Titans of the Deep | Free Documentary Nature

Sperm Whales - Titans of the Deep | Free Wildlife Documentary Dedicated scientists, equipped with cutting-edge technology follow the sperm whales as they dive to depths of 1,584 metres. Their efforts are not in vain as amazing new findings are revealed about the lives of these acoustically sensitive creatures. However, these findings pose new questions too. Are the increasing levels of man-made noise, that now pollute the ocean, affecting the whales and forcing them to swim into environments outside their natural habitat, such as the shallow waters of the North Sea?  The number of sperm whales that became stranded in the North Sea increased by 1000% in the 1990s. During this very same period the commercial search for oil in these waters, using seismic sonar technologies, also increased. Could there be a connection between the two? Until now, these two incidents have never been investigated.
