Summary: Swapped 7700 TC module, Upgraded 7700 firmware and IP address, Calibrated 7700, added range finder for water level - lost a week of met data, checked on strange tipping bucket data but no answer.

I arrived at 13:40 with Daphne. It was hot and sunny but an increasing wind kept it comfortable. The wetland is greening up. The water is a shocking shade of greenish brown.

The broken 7700 TC module was swapped out and the 7700 was calibrated. The 7700 sn TG1-0223 IP address was changed from 192.168.1.95 to 192.168.2.77. Then the firmware was updated from v1.0.21 to v1.0.27. Afterwards we checked to make sure the 7700 was connected to the 7550, the GHG columns were good and the USB was logging.
7700 broken TC: 0.08mmol/m3 CH4, 45 RSSI
7700 good TC clean: 1.95ppm CH4, 81.5RSSI
After calibration: 2.02ppm CH4, 80RSSI
After firmware update: 2.02ppm CH4, 80RSSI

The 7500 read: 411ppm CO2, 593mmol/m3 H2O, 27.7C, 101.1kPa, 84SS

We installed an ultrasonic range finder sn URM06-002 to measure water level. The sensor is on a short arm off the center-east side of the scaffolding about 68cm above the water level. The staff gauge read 51cm and the range finder was reporting 235mV (71cm). We forgot to download the met data before uploading a new program for the range finder so a week of met data was lost.

There were some strange numbers in the last batch of rain bucket data. We found no problems in the bucket or cabling. Daphne rewired the connections at the data logger.

We left at 15:00
