Variables

SortChem
  • Label: SortChem
  • Definition: A unique number assigned to each sample collected at a specific site at a specific date and time. The year that the sample was collected is followed by a dash and then a sequential number. For example, if 600 samples were collected in 2002, then the first sample collected is 2002-0001 and the last sample is 2002-0600.
  • Type: Nominal
  • Missing values: None specified
Site
  • Label: Site
  • Definition: Site Name. If a soil site, the site is described in the name by general location then specific feature (e.g., watertrack) then specific sampling point (1,2,3,...). Lake and stream sites use common names (e.g., Toolik) or LTER number codes. Exceptions in naming procedure are provided in the Code Information and in the AK-LTER_Site_Info.xls file.
