Overview

In 2011 Jessie Cable and Bob Bolton were awarded an epscor grant to do a project out at CPCRW looking at soil moisture and plant ecology during snow melt (or that is the gist I think).

Instructions for Salt Slug Solution/Q measurements (a start)

Water is able to dissolve ~350 g NaCl/liter H2O @ 25C, we went for about 200 g/l solution.

Using 18 liter container, means adding 3.6 kg salt

  1. Add H2O up to 12 liter mark
  2. Start magnetic stir thing
  3. Slowly add 2 kg salt to water. Be careful not to add too much at one time as it is possible to bury the stirrer.
  4. Add water to 18 L mark
  5. Add remaining 1.6 kg salt to the soup
    1. --> the process up to this point took me about 3 hours. Plan accordingly
  6. Continue stirring for a number of hours to ensure well mixed solution.
  7. Dilution process takes place the following days (to be continued).

-- In the field, we will borrow Jay Jones's YSI 556 MPS sensor.
