Copied the following procedure from what Monica wrote in her lab notebook just so I have it more accessible. I may also add a few things. This is for the byssal threads
data will be logged on this spreadsheet

Setup Procedure

  1. Open labview Program Omega DFG51-2 Force Gauge
  2. Open Amscope
  3. Open the google sheet
  4. Turn on the lights

Run Test

  1. Wet and clean the sample with seawater.
  2. Take a picture of the thread plaque using Amscope software.
  3. Calibrate the image and record the cross-sectional area in the google sheet and record the conversion factor.
  4. Turn on the force gauge by hitting the power button.
  5. Cut the sheet as needed and grip the thread using the hemostat clamp.
  6. Hang the clamp off of the force gauge.
  7. Push the down button on the motor and let it run until the sheet is laying flat and there is slack in the thread.
  8. Using the forceps, hold the sheet down and hit zero button.
  9. Start the labview logger software by hitting the arrow run button.
  10. Flip the motor switch up and record the data.
  11. Monitor the thread plaque during failure and record failure mode (see figure 1 below).
  12. After failure, hit the stop button and save the file with .txt extension.
  13. After one animal is finished, return to stack and write that it was tested.

Endy of Day Shutdown Procedure

  1. Turn off the force gauge.
  2. Clean workspace.
  3. Bind up the rest of the samples.
  4. Turn off the lights.
  5. Go to GitHub desktop and add summary, commit to main, and push it.
  6. Document in lab notebook


lots of pealers. I’m hoping weather or not they peel is not determined on how wet they are, it seemed if i wet them before force testing they were more likely to peel. All of them were at least damp though.
