A decadally resolved record of the 10Be peak at 41 kyr from the EPICA Dome C ice core in Antarctica is used to synchronize with the GRIP ice core in Greenland. The data permits direct synchronization of climatic variations around this period, independent of ice age-gas age uncertainties. The record was produced by G. M. Raisbeck and is used to compare with simulations from a thermal bipolar seesaw model.
Use Cases
- Synchronizing Antarctic and Greenland ice core chronologies based on the 10Be peak at 41 kyr.
- Modeling abrupt climate change events like Dansgaard-Oeschger event 10 using a thermal bipolar seesaw model.
- Analyzing the coeval relationship between Greenland events and Antarctic temperature maxima.
- Reproducing observed relative climate chronologies and Antarctic warming events between markers A1 and A2.
Strengths
- Decadally resolved record providing high temporal detail for the 41 kyr period.
- Enables direct climate synchronization independent of ice age-gas age difference uncertainties.
- Data is used to validate simulations from a thermal bipolar seesaw model.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
