π§ Exploring the deep sea (Big Ideas)
After almost 150 years of exploration and research we understand the sea is deep, dark and definitely different – the earth’s last great frontier perhaps – but how much do we know of what’s beneath the surface?
Kerry Howell discusses the history associated with mapping our oceans. From the original Challenger expedition which used dredges, to survey to modern day submersibles, which use sonar, video and machine learning which to slowly build a clearer picture. Responding to the question of deep-sea mining, Howell argues that we should not engage in such practices until we have a better understanding of the world below.
