We arrived about 13:10 PDT. It was warm and sunny with a nice breeze. The water level remains low.

Swapped 7500 for freshly calibrated one (removed sn 1594, installed sn 0041). Sara and Kathleen took water samples (3 in water).

Dennis says to add a boardwalk on the upper tier of the scaffold. Safety concerns.

7500 readings:
CO2 = 15.5 mmol m-3 (15.6 after cleaning, 16.0 after swap)
H2O = 680 mmol m-3 (580 after cleaning, 520 after swap)
p = 100.8 kPa
t = 28.1 C
Diag: 248 (same after cleaning, same after swap)
Sos: 348 m s-1

7700 readings:
CH4: 1.89 ppm
RSSI: 31% (73% after cleaning)
Topped off reservoir.

MET looked good. DO probe was reading 40 in water, 60 when raised out of water.
Cleaned Rad.
