How a grain of sand rewrote our ocean's history | Andrew Wheeler | TEDxDublin

This talk was given at a local TEDx event, produced independently of the TED Conferences. Earth is an oceanic planet, and its seabeds remain largely unexplored. Andrew Wheeler and his team use ROVs to collect core samples from the deep ocean, their layers revealing Earth's geological history. Andrew tells the story a grain of sand taken from the deep ocean, and how it has changed our understanding of how Ireland's landscape was shaped two million years ago. Andrew Wheeler is a marine geologist and ocean explorer. He has led many deep-water surveys mapping and sampling the seabed. Andrew's studies have taken him from the Arctic to sub-tropical Pacific, from mid-ocean ridges to shallow shelf, and he is fascinated by the geology of cold-water coral reefs. About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
