• roped off plots w/measuring tape to create an x-y
  axis and recorded coordinates of each specimen to
  map for later reference
• Took measurements for each specimen according to
  Guidelines volume equation

• Sometimes ran into irregular shapes, had to use
  other volume equations
• Equipment diameter tape, measuring tape,
  caliper, sonic height-measuring device

Had volumes, now needed densities to eventually
calculate mass

• Wanted to create a table of densities for every
  decay class and species we worked w/
• Took samples to dry
• Could not take from plots, so took from nearby

Methods for calculating densities

• Weighed wet samples and used equations to
  calculate their volume
• Cut a sub-sample from each sample (many were too
  big to fit in the labs oven) - calculated its
  wet wt. and vol. (calculated its of the larger
  sample for both wet wt. and vol.)
• Dried sub-samples in oven, obtained dry wt, then
  used sub-sample dry wts and values to calculate
  dry wt of original samples
• Dry wt dry mass used w/volume to calculate
  density of the sample
