title: Climarctic seasons

description: This dataset includes measurements of potential microbial functions (potential extracellular enzyme activities and microbial functional genes abundance) and soil physico-chemical properties (pH, nutrients, texture, etc) in biocrusts and underlying mineral soils in High-Arctic tundra near Ny-Ålesund (Svalbard) during each season along a toposequence.

 Description: Samples description
• sample number: sample list number (S1 to S126)
• season: season during which the samples were collected
• location: one of the two location where the samples were collected in the vicinity of Ny Alesund on Svalbard
• slope site: sites where the samples were collected along the toposequence (upslope = top of the slope, midslope = middle of the slope, downslope = bottom of the slope)
• soil layer: depth layer where the sample were collected (biocrust = 0-2 cm and mineral soil = 5-10 cm)
• replicate: replicated sampled (3 replicates per site)
