The permanently cold sediments of South Georgia were investigated in this study to identify the geochemical parameters that are linked to microbial community composition. To identify these parameters, pore water profiles of sulfate, sulfide, dissolved iron, ammonium, silicate, dissolved inorganic carbon, and phosphate were analysed. The results presented here were obtained during the RV METEOR M134 expedition (January - March, 2017) and contribute to our understanding of microbial community composition in surface sediments of South Georgia.
