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 come from a set of experiments conducted on the coastal waters near Davis Station in January 2017. The first set of data are from a transect near the Sorsdal glacier and out to sea, to characterise DMSP-mediated phytoplankton bacteria interactions along a salinity gradient. The second data set are from a series of incubation experiments to gain deeper insight into the role of various infochemicals in Antarctic phytoplankton-bacteria relationships. Specifically, DMSP, VitB12, Tryptophan and Methionine. The last data set is derived from two incubation experiments: a short term DMSP addition experiment to look at its uptake and utilisation by the microbial community; and a longer-term (5 day) stable isotope probing experiment to track DMSP through the lower trophic food web.
