Antarctic snow pit data collected along a 230 km route from Rappen to Svea via Aboa/Wasa stations. The dataset contains measurements from 15 snow pits approximately 1.5 meters deep and nine pits 0.5 meters deep, including temperature, density, crystal type, stratigraphy, moisture, and later lab analyses of pH, conductivity, and oxygen isotopes. It was collected by the FINNARP expedition snow team and published via NASA EarthData in 2010.
Use Cases
- Analyze snowpack stratigraphy and layering based on stratigraphy measurements.
- Model snow density profiles based on density column data.
- Study snow crystal morphology and evolution based on crystal type and size measurements.
- Investigate snow chemistry and isotopic composition based on pH, conductivity, and delta18O lab results.
- Map snow properties along a transect based on geospatial coordinates of measurement pits.
Strengths
- Contains measurements from 24 distinct snow pits (15 deep and 9 shallow).
- Includes a diverse set of 10 measured physical and chemical properties.
- Geospatial coverage spans a 230 km transect with specific northern and southern coordinates.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
