The Ups and Downs of Shark Movements with Dr Sammy Andrzejaczek

Tagging tiger sharks, seamount navigation, and a great white shark called Princess Sparkles...  This week, we're diving into the fascinating world of shark movement ecology with research scientist Dr Sammy Andrzejaczek to explore how and why sharks move about the oceans - in particular zooming in on their vertical space use and asking why some sharks take frequent dives to depths of over 1,000 metres. We also discuss the potential effects of the lunar cycle, and what white sharks are up to off the coast of central California. And, we take you behind the scenes as Sammy explains some of the different technologies that she uses to carry out this research and live her dream working with these incredible animals in the wild.
