Summary: Swapped 7500 head, cleaned DO probe, normal data collection
| We arrived at 1:15pm. Sunny with no wind. Brian stopped by for a chat. I collected data, Joe cleaned the sensors and swapped the 7500 head (replaced sn 0065 with sn 75H-2150 — now we have the correct head with the correct box). Sara checked the rain gauge—looked good. Sara also cleaned the DO probe and made sure it was submerged and filled the reservoir—it was ~1/5full. 7500 CO2: 223.2 umol/mol (389.9 after cleaning) (418.72 with new head) H2O: -37.5 mmol/m3 (90.9 after cleaning) (536.1 with new head) SS: 44.9% (74.1 after cleaning) (93.4 with new head) Pressure: 102.4 kPa Temperature: 18.43˚C SOS: 341.1 m s-1 (341.4 after cleaning) (341.9 with new head) 7700 CH4: 2.23ppm (same after cleaning) RSSI: 49.6% (66.5 after cleaning) Reservoir: OK Met:OK |
