Variables

Variables: 

Sample Number
  • Label: Sample
  • Definition: A number assigned to the sample taken on each Drought Time Period : PreDrought (1-36) and Drought (1-47)
  • Type: Nominal
  • Missing values: None specified
Location
  • Label: Location
  • Definition: Where along the soil catena sample was taken
  • Type: Code list
  • Codes:
    • Ridge = ridge along soil catena
    • Slope = slope along soil catena
    • Valley = valley along soil catena
    • Mid-slope = subset of slope along soil catena (middle part)
    • Low-slope = subset of slope along soil catena (lower part)
  • Missing values: None specified
Replicate sample
  • Label: Replicate sample
  • Definition: Number of sample replicate for a specific location and depth during the drought time period (1-6)
  • Type: Nominal
  • Missing values: None specified
Soil core depth
  • Label: Depth
  • Definition: Soil core depth were sample was taken from (0-15cm or 15-30cm)
  • Type: Physical quantity
  • Unit: centimeter
  • Maximum: 30
  • Minimum: 0
  • Precision: 1
  • Missing values: None specified
Drought Time Period
  • Label: DroughtTimePds
  • Definition: Whether soil sample is from before or after drought onset
  • Type: Code list
  • Codes:
    • PreDrought = soil sample is from before drought onset
    • Drought = soil sample is from after drought onset
  • Missing values: None specified
Sampling Month
  • Label: SamplingMonth
  • Definition: Month sample was taken; denotes year (in yy) and month
  • Type: Nominal
  • Missing values: None specified
pH
  • Label: pH
  • Definition: pH ( a number expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid, and higher values more alkaline. The pH is equal to -log10 c, where c is the hydrogen ion concentration in moles per liter)
