The “missing link†that triggered the ice ages
By Elise Kjørstad
Icebergs broke loose from Antarctica and travelled north.
As it got colder, they journeyed farther and farther north and carried large quantities of fresh water out to sea. This triggered global changes in ocean circulation, a new study published in the journal Nature reports.
Researchers have suspected that the Southern Ocean and Antarctica were crucial to global climate, but this has not been documented in the geological data until now, according to Margit Hildegard Simon, a researcher at Norce, the Norwegian Research Centre.
Simon partcipated in an expedition that collected samples from the seabed, off South Africa.
