Laboratory measurements of firn density and permeability from cores drilled at the WAIS Divide and Megadunes sites in Antarctica. The data covers the lock-in zone through pore close-off. Collected by the AMD_USAPDC organization and last updated in 2005.
Use Cases
- Model firn compaction processes by analyzing the relationship between density and permeability measurements.
- Calibrate remote sensing data for Antarctic snow properties using ground-truth density values.
- Study gas transport and trapping in firn using permeability data from the lock-in zone to pore close-off.
- Compare firn physical properties between the WAIS Divide and Megadunes sites using site-specific core measurements.
Strengths
- Data includes measurements from two distinct Antarctic field sites: WAIS Divide and Megadunes.
- Covers a specific and critical firn transition zone from lock-in through pore close-off.
Limitations
- Sample size and row count are unknown, limiting statistical assessment.
- Data is from 2005 and may not reflect current firn conditions.
- Geographic coverage is limited to two specific Antarctic sites.
Provenance
- Source
