Q: Have you had any measurements you'd question today?
A: Today the previous dissolved oxygen measurements had been at 5-7 mg per liter and this one was 8 so it seemed so much higher, but it wasn't an incorrect dissolved oxygen reading.
Q: What do you do if the data you collect in the field does not match your original hypothesis about how things should be?
A: Hear Audio Response:
Subsection 01
When you're on this AquaRAP thing, you shouldn't immediately throw out data, you should record it and then take a look at it after.
Then you can see if your theory about what the values should be as you go down and up stream are correct or not.
Q: Do you worry that your measurements are wrong?
A: We have to use common sense. If in the middle of the summer you are getting a measurement of -25 degrees or if you are in an acidic pool and the pH is 10, which is very alkaline, obviously something is wrong. You shouldn't anticipate what the data should be because if it is very wrong you might ignore it when, in fact, it is showing the real world.
