Snow samples for major ion, stable isotope, and trace metal analysis were collected every 10 kilometers along a traverse route connecting Syowa, Mizuho, and Dome Fuji stations in Antarctica. The dataset contains chemistry data from the top 10-20 cm of surface snow gathered during the 2007/2008 Japanese-Swedish Antarctic Expedition (JASE). Samples were analyzed by the National Institute of Polar Research, Japan, with trace metal analysis requested from a researcher in South Korea.
Use Cases
- Analyze spatial trends in major ion concentrations (e.g., sulfate, chloride) along the 10-km sampling transect to study marine vs. continental aerosol sources.
- Correlate stable isotope ratios (e.g., δ¹⁸O) with geographic coordinates and elevation to reconstruct regional paleoclimate signals.
- Investigate trace metal element profiles (e.g., lead, cadmium) to assess long-range atmospheric pollution transport to the Antarctic interior.
- Map geochemical gradients between coastal Syowa station and the high-altitude Dome Fuji site using sample location data.
Strengths
- Samples collected at a systematic 10-km interval along a defined traverse route.
- Multiple analytical suites performed: major ions, stable isotopes, and trace metals.
- Spatial coverage spans from coastal to interior East Antarctica, crossing significant elevation gradients.
Limitations
- Exact row count, column names, and sample size are unknown.
- Data is from a single field season (2007/2008), limiting temporal analysis.
- Potential for sample contamination during collection or analysis is not quantified.
