In Field Mat Sampling –
Target Layer Samples:
**document any variation**
|
The water at Fairy was
extremely hot and was splashing. |
Mat Dissection:
**document any variation**
|
We had a difficult time
trying to find a part of Imperial runoff to collect a mat that wasn’t dead.
It took Terry and Danny awhile until we found a spot. I was able to use the
tools and extract a piece of the mat. Liz and I then dissected the mats and
flash froze them. |
