Oxygen and deuterium isotopic composition data from the Dome Summit South (DSS) ice core drilled in Antarctica. Measurements include depth-specific values for dD and d18O in ppt SMOW. The dataset was collected by the Australian Antarctic Division's Glaciology labs during the 2015-2016 season.
Use Cases
- Reconstruct past temperatures by analyzing the correlation between d18O (ppt) and Sample Mid Depth (m).
- Study climate variability by examining trends in dD (ppt) across different depths in the ice core.
- Calibrate ice core dating models using the precise depth measurements from Sample Top Depth (m) and Sample Bottom Depth (m).
- Validate isotopic analysis methods by comparing results from the Picarro L2130-I analyser documented in this dataset.
Strengths
- Data includes two key isotopic measurements (dD and d18O) per sample for climate analysis.
- Sample depths are recorded with three precise metrics: top, bottom, and mid depth.
Limitations
- The dataset contains a single ice core (DSS1516), limiting spatial representativeness.
- The temporal coverage is a snapshot from one drilling season (2016), not a long-term series.
- Row count and total sample size are unknown, making statistical assessment difficult.
