Our Earth is a living planet that has changed over millions of years through the interplay of air, water, earth, and fire. Our climate is shaped by global ocean currents that transport massive amounts of heat around the globe. The Gulf Stream is particularly significant for our living environment in Europe. How were these currents discovered? What do the Viking Leif Eriksson and the navigator Cabral have in common? Who explored the depths of the oceans? How do these currents, which act like a conveyor belt, form? How does ocean research work today? All these questions are answered in this exciting feature about the exploration of our oceans. This audiobook was created in cooperation with GEOMAR. GEOMAR conducts ocean research worldwide, from the atmosphere to the seabed of the deep sea. An exciting adventure feature with original interviews, music, and sounds.
