A 2013 shallow ice core from Law Dome Summit provides high-resolution data on hydrogen peroxide, isotopic composition, trace ionic composition, and snow density. The core was obtained on February 4, 2013, at a specific Antarctic location (-66°46'21.2", 112°48'40.8") using a Kovac corer. This record is maintained by the Australian Antarctic Data Centre (AU_AADC) as part of ongoing climate monitoring.
Use Cases
- Calibrate hydrogen_peroxide concentrations against meteorological records to improve proxy interpretations.
- Analyze isotopic_composition data to reconstruct past temperature and precipitation variability.
- Study trace_ionic_composition for insights into historical atmospheric chemistry and aerosol deposition.
- Correlate snow_density measurements with accumulation rates and firnification processes.
Strengths
- Record provides very high-resolution data suitable for calibration with meteorological series.
- Core location (Law Dome Summit) is a well-established site for long-term climate records.
- Analysis includes multiple key climate proxies: hydrogen peroxide, isotopes, ions, and density.
Limitations
- Dataset size, row count, and temporal coverage beyond the 2013 sample are unknown.
- Geographic scope is limited to a single core location in East Antarctica.
- Data freshness is limited as the core sample is from a single day in 2013.
Provenance
- Source
- Australian Antarctic Data Centre (AU_AADC) via NASA Earthdata.
- Collection Method
- Ice core extracted with a Kovac shallow ice corer and analyzed in a laboratory.
- Time Range
- Sample date: 2013-02 -04. Long-term context from previous work on the dome.
- Freshness
- Single sample from 2013-02-04; part of an ongoing project but update frequency is unknown.
- Geography
- Law Dome Summit, Antarctica (Lat -66°46'21.2", Long 112°48'40.8").
