Climatic reconstructions from the southwestern Pacific for the period 20-10 kyr BP, presented by the Australian Ocean Data Network. The dataset is based on data from five sites along a transect from southern New Zealand through Australia to Indonesia, supported by 125 calibrated 14C ages. It identifies two periods of significant climatic change at around 17 and 14.2 cal kyr BP.
Use Cases
- Testing hypotheses about Southern Hemisphere climate teleconnections based on the multi-site transect.
- Investigating the onset of warming in the West Pacific Warm Pool around 17 cal kyr BP.
- Analyzing the climatic impact of Antarctic ice collapse during Meltwater Pulse-1A around 14.2 cal kyr BP.
- Assessing regional climatic variability across the Southwest Pacific during the Last Termination.
- Developing age models and quantified climate parameters for palaeoclimate records.
Strengths
- Data is supported by 125 calibrated radiocarbon (14C) ages.
- Reconstructions cover a specific and significant time period (20-10 kyr BP).
- Spatial coverage includes five sites along a transect from southern New Zealand to Indonesia.
Limitations
- The description notes severe geochronological constraints inherent to radiocarbon dating.
- The description states a lack of quantified climatic parameters.
- Column-level documentation is absent; field semantics must be inferred after download.
