Author: Sara Knox
Others: Patty, Cove, Joe

Summary: Data download. Built boardwalk. Moved scaffolding.

We arrived around 11:15 PDT. It was sunny, windy, and warm. Joe and Cove were hard at work building the boardwalk and moving the scaffolding.

I downloaded the data while Patty cleaned the 7700 and 7500. We also measured the instrument heights:

7700 Height: 304 cm
7500 Height: 303.5 cm

7500 readings:
CO2: 402 ppm (same after cleaning)
H2O: 360 mmol m-3 (345 after cleaning)
signal strength = 93.1% (93.6% after cleaning)
t: 20.0 °C
p = 101.6 kPa
sos = 343 m s-1

Current 7700 readings:
CH4 = 1.96 ppm (1.99 after cleaning)
RSSI = 54% (86% after cleaning)
Reservoir was full. Didn’t top off.

We downloaded the Met data after we came back in the afternoon to pick up Cove and Joe (around 3:45 PDT)

Joe and Cove built a 30 foot boardwalk running roughly north-south just to the east of the current flux tower location. We pulled all sensors and structure (except for one fence post) from the Tule tower location. The scaffolding was rebuilt at the end of the new boardwalk. All thermocouples were removed for retrofit but the other equipment was reinstalled on the scaffolding. Substantial rewiring and remounting will be needed when the flux equipment is moved to the scaffolding.
