Hydrogen Peroxide Measurements in Law Dome Ice Core

1993 measurements of hydrogen peroxide concentrations from the Dome Summit South (DSS) ice core at Law Dome. The dataset, submitted by the Australian Antarctic Data Centre (AU_AADC), provides chemical data extracted from glacial ice. It captures a snapshot of atmospheric chemistry preserved in the ice core from that specific collection period.

Use Cases

• Analyze historical atmospheric hydrogen peroxide levels using the measured concentration data.
• Correlate hydrogen peroxide concentrations with other ice core proxies like dust or isotopes for paleoclimate reconstruction.
• Model atmospheric oxidation chemistry over time using the hydrogen peroxide time-series from the ice core record.
• Calibrate or validate ice core gas extraction and measurement techniques for hydrogen peroxide.

Strengths

• Data originates from a specific, well-documented ice core (Dome Summit South, Law Dome).
• Provides direct chemical measurements for a key atmospheric oxidant (hydrogen peroxide).

Limitations

• Dataset is temporally limited to a single submission date (1993), with no clear time range for the ice core samples.
• Sample size, row count, and data completeness are unknown.
