Turtles are survivors, navigators, voyagers: criss-crossing Earth’s seas while continents moved and oceans grew and shrunk.  But the modern ocean is presenting them with more challenges than ever. This month, oceanographer Helen Czerski will be swimming with Earth’s turtles, meeting the different species, spying on their lifestyles and seeing the ocean through their eyes. How do they manage their incredible feats of navigation?  And what do we need to do to make sure that these fabulous animals sail with us into the ocean’s future? With special thanks to Dr Graeme Hays from Deakin University, Holly Stokes, Dr Nicole Esteban from the University of Swansea, and Dr Liliana Colman from the University of Exeter.
