Clues about the formation of major ice sheets on Antarctica have been found in mud cores drilled in Mississippi, providing an important lesson about a major climate cooling event, sometimes known as the Grande Coupure or great cut. In a new paper published in Nature Communications, an international team of scientists led by the University of Birmingham have studied material taken from cores drilled near Jackson, Mississippi in the USA. Material found in layers of the cores suggest that there was a major transfer of carbon from plant remains in coastal environments into the atmosphere, driven by sea level falls of around 40 metres as Antarctic ice caps formed.
