Heavy metals in mosses near a mining road in Alaska, USA.

moss

Format

An sf object with 365 rows and 10 columns:

  • sample: A factor with a sample identifier. Some samples were replicated in the field or laboratory. As a result, there are 318 unique sample identifiers.

  • field_dup: A factor representing field duplicate. Takes values 1 and 2.

  • lab_rep: A factor representing laboratory replicate. Takes values 1 and 2.

  • year: A factor representing year. Takes values 2001 and 2006.

  • sideroad: A factor representing direction relative to the haul road. Takes values N (north of the haul road) and S (south of the haul road).

  • log_dist2road: The log of distance (in meters) to the haul road.

  • log_Zn: The log of zinc concentration in moss tissue (mg/kg).

  • geometry: POINT geometry representing coordinates in an Alaska Albers projection (EPSG: 3338). Distances between points are in meters.
