125 calibrated 14C ages support climatic reconstructions from five sites across the Southwest Pacific. The Australian Ocean Data Network provides this dataset for the period 20-10 kyr BP. Two periods of significant climatic change are identified at around 17 and 14.2 cal kyr BP.
Use Cases
- Test hypotheses about Southern Hemisphere climate teleconnections based on reconstructions from a transect of five sites.
- Analyze timing of climatic events like Meltwater Pulse-1A based on identified change points at 17 and 14.2 kyr BP.
- Study regional climate variability during the Last Termination based on reconstructions spanning 20-10 kyr BP.
- Assess the role of the West Pacific Warm Pool in global climate change based on onset of warming evidence.
Strengths
- Reconstructions are supported by 125 calibrated 14C ages.
- Data covers a key region across a transect from southern New Zealand to Indonesia.
- Identifies two specific periods of climatic change at around 17 and 14.2 cal kyr BP.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- The description notes severe geochronological constraints and lack of quantified climatic parameters.
