Oxygen and deuterium isotopic measurements from the Dome Summit South Law Dome ice core drilled in the Antarctic 2014-2015 season. Data includes sample depths and isotopic content values. The dataset was submitted by the Australian Antarctic Data Centre and the analysis was performed in 2015.
Use Cases
- Analyze the relationship between dD (ppt) and d18O (ppt) values to study climate proxies.
- Model ice layer age-depth relationships using Sample Top Depth (m) and Sample Bottom Depth (m) columns.
- Correlate Mid sample depth (m) with isotopic values to reconstruct historical temperature trends.
Strengths
- Includes precise geographic coordinates (Lat -66°46'17.1", Long 112°48'31.3") for the ice core location.
- Specifies the analytical instrument used (Picarro L2130-I water isotope analyser) and the performing lab (AAD Glaciology labs).
Limitations
- Sample size (row count) is unknown, limiting statistical assessment.
- Temporal coverage is limited to a single drilling date (07/02/2015).
