Who keeps ocean science afloat miles off the coast? Zoe meets John ‘Mac’ McDonald, a former Royal Marine turned ocean operations expert at @PlymouthMarineLaboratory. With military precision and a passion for the sea, Mac plays a crucial role in supporting scientists to protect our oceans.
Zoe heads to sea to join Mac aboard a floating research lab and discovers how data is collected 24/7—from weather sensors to baby crab larvae. Plus, marine biologist Amanda Beesley shows Zoe how microscopic plankton reveal the bigger picture of climate change.
Join Zoe in this episode as she explores a career that proves science isn't always in a lab coat—and that the ocean is a high-tech, high-stakes frontier for discovery.
