dc.description.abstractThe terrestrial and oceanic salt (NaCl) components in 39 dust samples from eight sites across south eastern Australia have been calculated from chemical data derived by ion beam analysis (IBA). For samples identified as having a positive terrestrial salt ratio (TSR; i.e., the abundance of terrestrial salt relative to total salt expressed as a percentage), back trajectory analysis (estimation of the path of the wind affecting the site) was used to verify the likelihood of a terrestrial source for such salt. This procedure indicated that the terrestrial salt input to south eastern Australia is non-negligible compared to that of sea salt and the most likely sources of the terrestrial salt deposited in such area are the inland saline regions of the Lake Eyre and Murray Darling Basins. Terrestrial salt ratio values readily screen out the majority of samples for which a terrestrial salt component is unlikely. Thus, calculating the ratios to identify samples which are potentially influenced by terrestrial salt (e.g., prior to conducting a back trajectory analysis on such samples) appears to be useful, especially since such determinations can be done with small sample sets for which statistical analysis is not appropriate.
