Session 1: The Terrestrial Fingerprint of a Heinrich EventShow Details

This session will focus on Heinrich events as recorded in the ice-core records and other terrestrial sites. We will investigate the importance of chronological uncertainties and how they might affect our understanding of synchroneities (or not) in climate signals from disparate locations.

Keynote: Eric Wolff

Session 2: Ocean Processes at High Latitudes Show Details

This session will investigate the role of oceanographic processes at high latitudes in maintaining the AMOC slowdown during Heinrich events. In particular, this session will focus upon the stable oxygen isotope anomaly, which is evident over a vast area of the Nordic Seas and the Northern North Atlantic, and will question how this may have related to physical processes.

Keynote: Henning Bauch

Session 3: Oceanographic and Atmospheric Processes at Low LatitudesShow Details

This session will investigate marine, terrestrial and atmospheric processes at low latitudes. We will question whether we can reliably attribute chronological relationships between signals recorded at both low and high latitudes, and if we are able to decipher processes from these offsets.

Keynote: Syee Weldeab

15:50 -
Coffee and Discussion

We aim to use this session to summarise the key findings from the previous session, to discuss the wider reaching implications and to address where further future research is required. We also pose the question whether the proposed definition of a Heinrich event in Stanford et al. (2011) is appropriate.

Chair: Claude Hillaire-Marcel

Evening reception, lecture and dinnerShow Details

Professor Clive Gamble will be presenting a seminar on how Heinrich events impacted upon the development of Humans.

Session 4: Ice-sheets and Sea-levelShow Details

This session aims to investigate whether there was a significant rise in eustatic sea-level during Heinrich events and whether we see the impact of this on marginal basins, e.g., do we see a change in watermass communication. We will also assess whether the associated sea-level rise/freshwater fluxes had an impact on AMOC stability, as indicated by results from ocean-climate models.

Keynote: Eelco Rohling

Session 5: IRD and ProvenanceShow Details

During this session we aim to address the question of which ice-sheets were acting and reacting, and when, and whether precursor ice collapses had a significant impact upon the AMOC. In the broader sense, this session will address the issue as to whether the location of freshwater forcing is more important than the magnitude of freshening.

Session 6: Were all Heinrich Events the same?Show Details

This will draw upon evidence from studies of Heinrich Events from beyond the Last Glacial Cycle to address the question as to whether all Heinrich events were the same.
