AAS_926_Bunger_Hills_Salt_Sediment_Weathering
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
The data consists of an excel workbook with five sheets;
1. Location and mineralogy of samples of salt taken from the land surface.
2. Location and elemental composition of aqueous extracts taken from surface sediments, on a 1 x 1 km grid.
3. Weathering criteria (frost cracks, glacial polish, tafoni, wind pits, sand accumulations) on a 1 x 1 km grid.
4. Glacial sediment grain size statistics, from samples collected on a 2 x 2 km grid.
5. Antarctic seawater chemistry from the literature.

Purpose
We wished to determine the role of salt on the distribution of rock weathering, periglacial features, and the distribution of biota.
Quality
Samples were collected before GPS were broadly available. We used an Australian Antarctic Division SPOT image-based map for location. Sampling points are typically within 100 m of their target location, except where water bodies (lakes, marine inlets) prevented their collection. We took samples up to 400 m (but typically 100 m) of the location, to be representative of the grid cell. The actual grid reference of sampling was recorded.
