East End Wetland
2014-01-10

We arrived about 14:00 PST. It was warm, pretty calm, and sunny. Seedlings of tules or cattails and/or material from the East Pond has been planted/placed at close intervals along the berms to facilitate quick vegetation establishment at the site. We met Bryan + company and Wyatt at the site. Bryan is going to install a sampling boardwalk for Wyatt ~100m north of the tower. Heâ€™ll construct one for us from the berm out to the tower.

We downloaded data and cleaned the flux instruments. There was a leak in the filter of the 7700 reservoir and Joe sealed it with silicone tape. Denis loved the tape so much he vowed to obtain his own supply (stocking stuffer next year???).

7500 readings:
CO2 = 16.9 mmol m-3 (17.3 after cleaning)
H2O = 445 mmol m-3 (same after cleaning)
Diag: 250 (249 after cleaning)
t = 19.3 C
p = 102.2 kPa

7700 readings:
CH4: 2.08 ppm (same after cleaning)
RSSI: 34% (68% after cleaning)
Reservoir was nearly empty.

MET looked good.
There was bird doodie in the rain gauge and all over the solar panels -> cleaned.
Radiometers were supper dirty from bird feet.
