Tonzi: 2001-04-03 11:30:00 (DOY 93)
Author: Nancy Kiang
Others: Lianhong

Summary: Working on sap flow stations, tree cores.

WHO: Nancy Kiang, Lianhong Gu
WHERE: Tonzi Ranch
WHEN: 4/3/01
WEATHER: ~65°F, hazy, sunny
WHAT:
- Replace broken heaters at Saplow Q setup.
- Take tree cores from sapflow trees.
- Download soil, met, and sapflow data.
- Reset gillsonic SETUP file to rawdata=1 (log raw data)
- Checked if computer on standard time: yes.

Arrived ~11:30 am.

- Mr. Tonzi showed us a tree, 30.5" circumference (24.7 cm diameter), that he is willing to cut down for Nancy's lab experiment.

- Interrupted understory system 12:46-1:26 pm. PC208W was not running.
-Downloaded CR10X2, CR23X, CR10X4, CR10X5 data
o put *.dat files into folder tonzi/tonzi032401to040201
- Checked computer is on Standard Time
- Reset SETUP file for gillsonic to rawdata = 1, to log raw data.

- Interrupted CR10X4, Sapflow Q at 1:30 pm
- Replaced broken heaters in Sapflow Q setup:
- Tree 245, installed heater H16
- Tree 255, installed heater H17
- See notebook for resistances with and without long leads.

- Lianhong took cores from sapflow trees (Haglöf increment borer, #63269, 3-thread, 5.15 mm core, 12", borrowed from Todd Dawson's lab):
- Got all trees except #79 (borer bit broke)
- Tree #252 is rotten inside (a lot of water gushing out through borer hole)
o Lianhong remarked that knobby trees with many low branches tend to be unhealthy trees.
o Core is okay through sapwood, but heartwood is rotten.

- Finished at 3:00 pm and went to UC Davis to see Robert May talk.
