The unique location of the station makes it suitable for different research domains such as glaciology, atmospheric sciences, astronomy, etc. Furthermore, it is used as a test bed for long-duration spaceflights to study the physiologic and psychological adaptation to isolated environments. A total of 96 samples were collected at eight different locations in the station at regular intervals. The airborne bacterial contamination was for 90{\%} of the samples lower than 10.0×102 colony-forming units per cubic meter of air (CFU/m3) and the total bacterial contamination increased over time during confinement but diminished after reopening of the base. Viable airborne bacteria with different morphology were identified by biochemical analyses. The predominant microflora was identified as Staphylococcus sp. (24.9{\%} of total) and Bacillus sp. (11.6{\%} of total) and was associated with human activity, but also environmental species such as Sphingomonas paucimobilis (belonging to the α-Proteobacteria) could establish themselves in the airborne population.
