Data from the Evans Piedmont Glacier, Victoria Land Coast, Antarctica, includes a 180-meter ice core, multiple snow profiles analyzed at 1cm resolution, and three snow pits. Measurements cover snow chemistry, isotopic composition, dust content, density, temperature, and crystal structure, collected by SCIOPS researchers. An automatic weather station installed in November 2004 recorded meteorological variables.
Use Cases
- Reconstruct past atmospheric conditions using isotopic composition and major ion data from 1cm-resolution snow profiles.
- Analyze dust content and mineralogy from snow profiles and ice cores to infer historical wind patterns and source regions.
- Model glacier mass balance and firn densification using density measurements from snow pits and the 180m ice core.
- Correlate snow accumulation rates from automatic weather station data with chemical signals preserved in the snow pack.
- Study gas bubble properties like porosity and geometry from ice core chips to understand past atmospheric gas trapping.
Strengths
- High-resolution snow profile data at 1cm intervals for chemistry and isotopic analysis.
- Multi-method data collection including a 180m ice core, GPR surveys, snow pits, and an automatic weather station.
- Detailed physical measurements including snow crystal structure, temperature profiling at 5cm resolution, and density.
Limitations
