Event details
Heinrich-event-magnitude ice-rafted debris deposition and its provenance in the earliest Pleistocene sub-polar North Atlantic Ocean
Abstract
Since the pioneering works of the 1970's, it has been known that long-term cooling led to widespread glaciation of the northern hemisphere (NH) from ~3 Ma. Yet, the mechanisms responsible for this trend remain elusive. This talk will address the following related questions:
1) Why did there exist Last Glacial-magnitude IRD fluxes to the earliest Pleistocene sub-polar North Atlantic Ocean when it is generally accepted that NH ice-sheets growing during this time interval were smaller than their late Pleistocene counterparts?
2) What does the answer to Question 1 reveal about the likely origin of northern hemisphere glaciation?
Key facts
This talk is open to all staff and students in NOCS.
