Méthodes d'échantillonnage
Sampling of air mass above the boundary layer for surface influence was achieved by mounting the apparatus in a helicopter with an external sampling port.
Etendue de l'étude | Air mass at near-surface (1.5m above ground) and underlying soil was sampled from 11 to 23 January 2017 at valley and elevated locations throughout the Wright Valley, McMurdo Dry Valleys, Antarctica. Comparison samples were taken from the North Island of New Zealand. |

Description des étapes de la méthode:
- Total DNA was directly extracted using a CTAB protocol. DNA yield for these ultra-low biomass samples was quantified using the Qubit 2.0 Fluorometer (Invitrogen) in the range 1.06-8.44ng. Samples were then stored at -20 C. Illumina MiSeq libraries were prepared as per manufacturer’s protocol (Metagenomic Sequencing Library Preparation Part # 15044223 Rev. B; Illumina, San Diego, CA, USA) and with PhiX positive controls. Bacteria and Fungi were targeted with domain-specific PCR primers PCR1 forward (5’ TCGTCGGCAGCGTCAGATGT GTATAAGAGA CAGCCTACGG GNGGCWGCAG 3’) and PCR1 reverse (5’ GTCTCGTGGG CTCGGAGATG TGTATAAGAG ACAGGACTAC HVGGGTATCT AATCC 3’) and the internal transcribed spacer region of fungal 18S and 5.8S rRNA genes: ITS1 forward (5' CTTGGTCATTTAGAGGAAGTAA 3') and ITS2 reverse (5' GCTGCGTTCTTCATCGATGC 3').
