Law Dome Ice Core Isotopic Composition from 2014 Antarctic Season

Dome Summit South glacial isotopic composition data contains deuterium and oxygen isotope measurements for the DSS1314 ice core. The dataset was collected by the Australian Antarctic Division's Glaciology labs during the 2013-2014 Antarctic season. Measurements include sample depths and isotopic content in ppt SMOW.

Use Cases

• Model past temperature variations by correlating d18O (ppt) values with Sample Mid Depth (m).
• Analyze deuterium-excess for moisture source history using dD (ppt) and d18O (ppt) columns.
• Construct a depth-age model for the ice core by stratifying measurements from Sample Top Depth (m) to Sample Bottom Depth (m).
• Calibrate isotopic records from the Picarro L2130-I analyzer against other Antarctic ice cores using the Core identifier.

Strengths

• Data is tied to a specific, documented ice core (DSS1314) with precise location coordinates.
• Includes two key paleoclimate proxies: dD (ppt) and d18O (ppt) measurements.

Limitations

• Sample size and row count are unknown, limiting statistical power.
• Temporal coverage is limited to a single drilling date (02/02/2014).
• Data format is an Excel file (.xlsx) which may require conversion for programmatic analysis.
