gradient_chemistry

This file contains chemical data for 25 streams in New Zealand across an acid mine drainage gradient. pH and conductivity were recorded in the field using standard meters (YSI 550A & YSI 63). Element concentrations were estimated using ICPMS analysis of a filtered (pore size = 0.45 um) water sample collected in the field. site = site name. cond = specific conductivity (microsiemens per centimeter). Elemental concentrations are reported in micrograms per liter.
