design: Samples were collected in different distances from the glacier terminus in Barton Peninsula,  located in King George Island (Antarctic). A total of 250 mg of soil samples were used to extract DNA and the PCR products of fungal sequences were amplified using universal primers ITS1F and ITS2 and the PCR products of bacteria were amplified with the primers 515F and 806R. Sequencing was peformed in Illumina MiSeq.
