Oxygen isotope results from 73 snow samples collected at 25 sites along the 1983/84 Russian traverse route from Mirny to Dome C in Antarctica. Analysis was performed by the Laboratoire de Geochimie Isotopique. The data documents deuterium-excess analysis from a specific Antarctic expedition.
Use Cases
- Analyzing deuterium-excess values across 25 traverse sites to study regional climate patterns.
- Correlating oxygen isotope ratios with sample collection locations along the Mirny-Dome C route.
- Using the 73 sample results as a historical baseline for modern Antarctic snow composition studies.
Strengths
- Data comprises 73 distinct snow samples from a defined expedition.
- Samples were collected from 25 specific geographic sites along a traverse route.
- Analysis was conducted by a specialized laboratory (Laboratoire de Geochimie Isotopique).
Limitations
- Small sample size of 73 records limits statistical power for broad conclusions.
- Data is temporally stale, with collection ending in March 1984 and no updates since.
- Geographic coverage is limited to a single traverse line in East Antarctica.
Provenance

- Collection Method
- Snow collected via 1200mm metal tube, melted in situ, with water samples analyzed in a lab.
- Time Range
- 1983/84 Antarctic field season.
- Freshness
- Data collection ended on 1984-03-09 with no subsequent updates.
