Summary: Site flooded. Data download. Build boardwalk to tower. Wasp problem in Met box.
| Twitchell Rice 2013-11-06 We arrived about 11:45 PST. It was sunny with high hazy clouds, warm, and calm with a very slight breeze from the east. The field is fully flooded, water table about 20 cm above the surface. We built a boardwalk out to the tower. The Met box was full of wasps, which are entering through the dislodged silicone filling the holes in the bottom. We need to seal these holes again next time. 7500 readings: CO2 = 397 ppm (410 after cleaning) H2O = 420 mmol m-3 (309 after cleaning) signal strength = 81% (88.1% after cleaning) t = 22.5 C p = 102.8 kPa sos = 345.2 m s-1 7700 readings: CH4 = 2.1 ppm (same after cleaning) RSSI = 12% (71% after cleaning) Refilled reservoir. |
