Summary: Data download. Recorded serial numbers for optical DO probes. Swapped out 2% CO2 probe for 4% probe. Updated 7500 firmware.
| West Pond 2014-10-02 We arrived around 12:30 PDT. It was hot, sunny and calm-ish. Site is still green. Took water samples. Downloaded data. Got serial numbers from the optical DO sensors. Removed the 2% Forerunner CO2 probe (sn GP20140009) and installed a 4% Forerunner probe (sn GP20140021). After several minutes, the temperature voltage read about the same and the CO2 voltage was low (350 mV) but rising. There is a new wasp nest under the top scaffold. Bring wasp spray next time. Updated 7500 firmware to 7.3.0. DO sensor serial numbers according height above soil surface (within water column): 2 cm: sn 1221 7.5 cm: sn 1219 13 cm: sn 1220 Readings (after cleaning): CO2 = 400 ppm H2O = 545 mmol m-3 signal strength = 94.45% p = 101.3 kPa t = 27.8 C sos = 35.6 m s-1 CH4 = 2.0 ppm RSSI = 77% Reservoir almost full. Met looked good. Cleaned rad. |
