Metal Fractions in Antarctic Soils from Casey and Wilkes Stations

Antarctic soil samples from 11 sites around Casey and Wilkes stations detail four distinct metal fractions. Data includes diffusive gradient in thin-film (DGT) labile, water-soluble, dilute-acid extractable, and total recoverable metal measurements. The dataset was collected during the 2017-2018 summer season by the Australian Antarctic Data Centre (AU_AADC).

Use Cases

• Compare bioavailability by analyzing the DGT-labile metal fraction against the total recoverable metal fraction.
• Assess metal mobility by correlating the water-soluble fraction with soil physicochemistry data.
• Model environmental risk by examining the dilute-acid extractable fraction as an indicator of loosely bound metals.

Strengths

• Data covers four distinct metal fractions per sample, enabling multi-faceted analysis.
• Samples collected from 11 specific sites, providing spatial context within the Windmill Islands.

Limitations

• Sample size is limited to a single summer season (2017-2018).
• The exact number of soil samples and rows of data is unknown.
