Characterising the microbial interactions that drive organic sulphur cycling in Antarctic watersThese 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 in
