Summary: Swapped 7700, upgrade CR1000 os, water level low, installed USB miniDOT

Sherman Wetland
2018-05-10

I arrived at about 10:30. Patty had just arrived and was still sitting in her car. It was cool and windy with high thin clouds. The water level is low with ground showing in many places. The Eos CO2 sensor was just barely in the water and the conductivity sensor was high and dry.

I swapped the 7700
sn TG1-0421 off: 1.96ppm CH4, 67.2RSSI â€“ 79.9 after cleaning
sn TG1-0423 on: 1.94ppm CH4, 69.5RSSI
After the swap, the clocks were about 10min ahead. I set the 7700 clock from 10:15 to 10:06. I did not check the wash reservoir.

The 7500 read: 401ppm CO2, 693mmol/m3 H2O, 18.8C, 101.4kPa, 99.8SS

I downloaded the met data and ejected the card before I updated the CR1000 sn 38211 OS from v27 to v32.02. This completely reset its configuration to default settings. I reloaded the program. There were two versions on the laptop 20170714 and 20170814. The 20170714 program had a newer modification date and the other program had two output tables in it. I opted for the 20170714 version. I also had to adjust its ftp settings.

I cleaned the radiometers. The longwave in was very dirty.

I was planning to put in a new USB miniDOT to measure DO, but because the water level was so low I hesitated. Finally, I put in sn 906606 on a rope two posts south of the tower along the board walk.
