Overall aims

  • Quantify chemical and physical weathering rates for two Arctic catchments.
  • Determine the impact of glaciation on (shale) weathering rates.
  • Determine the impact of changes in permafrost depth on weathering rates.
  • Be able to explain the chemical composition of the streams in terms of specific weathering reactions.
  • Provide infrastructure for long-term monitoring of these two arctic catchments.

Specific aims for 2012

  • Successfully install and calibrate the meteorological and hydrological monitoring equipment.
  • Calculate suspended sediment budgets for both streams.
  • Calculate annual and precipitation corrected dissolved flux budgets for major elements for both catchments.
  • Perform mineral separations and determine the chemical compositions of minerals for an initial set of rock samples.
