Summary: Regular data collection/cleaning, replaced eosGP pCO2 sensor
2021-03-16 Mayberry I arrived at 17:10 PDT. It was a cool day with a cold breeze. There are some green reeds coming up on the edges of channels. The staff gauge read 43cm. I downloaded met, camera, and USB GHG data. The reservoir was 90% full; I refilled it. I downloaded FD data and cleared its memory. I cleaned flux and rad sensors. The conductivity sensor was clean. The eosGP sensor has been reading noise sporadically since December, so today I brought a replacement. I was planning to do an intercomparison with both eosGP sensors, but the current sensor was reading noise again, so I decided just to bring the current sensor back to the lab for testing. sn GP20160070 came off and sn GP20150111 went on. I’m not really sure if the newly installed sensor is working because the CO2 readings were close to 0, but maybe it needs more time to equilibrate with the water. LI-7500 readings: CO2 415ppm H2O 386ppm T 15.6C P 101.6kPa SS 97-->98 after cleaning LI7700 readings: CH4 1.97ppm RSSI 68--> 84 after cleaning I left at 18:00 PDT. |
