| Paleo Slide Set: Heinrich Events: Marine Record of Abrupt Climate Changes in the Late Pleistocene |
| Variability in sediment properties within Heinrich and non-Heinrich sediments from same core. | |
|
Other researchers are taking a closer look at variability within Heinrich events. This is particularly effective at sites close to former ice sheet margins, such as the Hudson Strait where
Heinrich events can exceed 0.5 m in thickness. Moreover, these thick deposits were laid down during relatively short spans of a few hundred years, very rapidly in geological terms. Not only were the changes between Heinrich and non- Heinrich events
abrupt, but conditions within Heinrich events could also vary to a greater extent than once thought.
