We arrived around 09:00 PDT, meeting Kuno and Kaido from Estonia who were looking to take some soil respiration measurements in drained peat. It was sunny, breezy, and warm. The site is unchanged. I downloaded data and did well depth while Sara did veg height, moisture point, and spectral. We then removed the entire soil CO2 system to place at Alfalfa next week.

LGR readings: 1.90 ppm, 09:19, 22.7 C, 146.3 Torr, 14.70 us, 10 Hz

7500 readings:
CO2: 15.8 mmol m-3 (16.4 after cleaning)
H2O: 800 mmol m-3 (780 after cleaning)
P = 101.5 kPa
T = 25.0 C
Diag: 248 (same after cleaning)

Soil CO2 looked good. Downloaded all data before removing.
Met looked good. There was no water in the wells. This is probably because Mayberry Slough has been really low. Bryan said they fixed the pumps for the slough just recently, so perhaps the water table will rise soon.
Cleaned rad.

Veg Height (cm): Tape measure from ground to top of plant - mostly dried out
80, 12, 5, 20, 50, 11, 43, 70, 62, 20, 18, 80, 8, 47, 50, 31, 57, 54, 56, 63, avg = 41.9, stdev = 24.37
