Variables

Variables: 

Isotope_number
  • Label: Isotope Identifier
  • Definition: The identifier given to all fish to link that fish to the muscle sample run for isotope analysis and their gut contents
  • Type: Nominal
  • Missing values: None specified
River_Number
  • Label: River Number
  • Definition: The number assigned to the river estuary from which the sample was taken
  • Type: Code list
  • Codes:
    • 1 = Rio Espiritu Santo (Espiritu Santo River)
