Summary: Regular data collection, field flooded but bare
| Arrived at 11:30. It was cloudy/overcast, cool with a light breeze. The field was completely flooded but bare, no emergent vegetation visible at all. Refilled wash reservoir, was half empty. Cleaned GHG sensors. Collected USB GHG data, collected met data from CR1000. One of the soil HFPs (SHF2) reading had the opposite sign as the other two. Kyle checked it in and it was floating and not buried in the soil. He pushed it back in the soil and tried to cover it with some soil. The reading stabilized to a similar reading as the other two plates after that. Left at 11:50 but came back at 12:30 to check on the camera. The camera was off and but it looked like there were pictures up until November 20 on the camera. We did not collect the pictures but restarted the camera. After some fiddling around Kyle got it to run the autocam program. LI7500 readings: CO2 440.97 umol/mol H2O 531.9 mmol/m3 T 13.95 Celsius P 102.60 kPa SS 88.8 -> 95.2 after cleaning LI7700 readings: CH4: 2.2 RSSI: 33 -> 67 after cleaning |
