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.
