PP043:
Twenty-five years of Heinrich Events research: what we have learned so far about the past global changes





Session ID#: 25813

Session Description:
In 1988, Heinrich discovered six iceberg-rafting events from the Dreizack seamount. However, late Bond and Broecker of LDEO placed the findings of Heinrich into a past global change context in 1992 that caught the imaginations of paleo-communities. Since then, search for the impacts of H-events on the ocean and atmospheric circulation across the globe has been intensified. The objective of the session on H-events is to bring together a diverse group of researchers who deal with paleo-proxy records such as ice cores, marine sediments, terrestrial archives and coupled ocean-atmosphere models to discuss advances in understanding the mechanisms of these events. Abstracts are solicited for any topic relevant to the above or other questions relating to H-events: (a) ice cores records from both poles and high altitudes; (b) marine sediment records; (c) terrestrial proxy records of abrupt climate change; and (d) coupled climate models and their performance in simulating H-events.
