| Zusammenfassung |
| The climate during the last glacial showed a much higher variability than the Holocene
climate. The strongest variations were caused by Heinrich events with a recurrence
interval of 7 000 yrs. They are manifested in ice rafted debris layers in North Atlantic
sediment cores and in many other climate proxies. The debris stems mainly from
the Laurentide Ice Sheet which experienced massive surges during the Heinrich
events.
We use the modified Parallel Ice Sheet Model mPISM coupled with the Atmosphere-Ocean
General Circulation Model ECHAM5/MPIOM to study Heinrich events in transient
simulations. We show first results from coupled simulations and compare them with
stand-alone runs. |
