Iron, manganese, and aluminium concentrations are measured in both modern surface snow and ancient ice cores from East Antarctica. Data originates from modern sites in Prydz Bay, Dumont d'Urville Sea, Ross Sea, and Princess Elizabeth Land, and ancient cores from Law Dome and Wilkes Land. This work was completed by the Australian Antarctic Data Centre as part of ASAC project 827, with data last updated in 1998.
Use Cases
- Analyze temporal trends in iron, manganese, and aluminium concentrations to reconstruct historical atmospheric dust loading.
- Compare trace metal levels between modern snow samples and ancient ice cores to study changes in deposition sources.
- Correlate metal concentration data from specific sites like Law Dome with other paleoclimate records.
- Map the spatial distribution of trace metals across collection sites in Prydz Bay, Ross Sea, and Princess Elizabeth Land.
Strengths
- Data covers multiple distinct geographical regions across East Antarctica.
- Includes both modern surface snow and ancient ice core samples, providing a temporal dimension.
Limitations
- Dataset is temporally stale, with last update recorded in March 1998.
- Specific sample counts, row numbers, and measurement precision are unknown.
- Geographic coverage is limited to specific East Antarctic sites, not continent-wide.
