All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description

These data describe the physicochemistry and metal content of soils collected from 11 sites around Casey and Wilkes stations in the Windmill Islands, East Antarctica during the 2017-2018 summer season for project AAS4326. Four metal fractions are reported in these data: (1) diffusive gradient in thin-film, DGT, labile fraction; (2) water-soluble fraction; (3) dilute-acid extractable fraction, and; (4) total recoverable metal fraction.

The excel spreadsheet contains a number of worksheets which explain acronyms and units used as well as several sheets of data.

Purpose

These data were used to compare the DGT-method for measuring labile metal concentrations in soils to traditional chemical extractants. These data will support the validation of DGT for use in metal-contaminant environmental monitoring and impact assessment in Antarctica.

Quality

There were no problems with data collection or analyses. This dataset includes quality assurance such as instrument limits of detection and metal recovery for various certified reference materials.

Access

These data are not yet publicly available for download.
