Summary: Regular data collection/cleaning, swap 7700 for calibration

2018-04-05
West Pond

We arrived at 11:20. It was cool, windy, and overcast. We noticed someone had tried to cut open the shipping container by the tower road, but the container doors were still chained together. Some tule are coming up in the canopy, but none above the litter yet. The water was not visible and all the water sensors were out of the water (CO2, salinity, O2).

I downloaded met and USB GHG data. I didnâ€™t bring the SD card reader, so I did not get the camera data, but Kyle checked that the camera was on and taking photos. I refilled the wash reservoir; it was mostly full. Kyle cleaned the EC and rad sensors.

We swapped the 7700: sn TG1-0424 came down and sn TG1-0224 went up. I had to manually connect the 7700 in the LI-7550 interface, and changed the 7700 clock from slave to automatic mode. I reset the box and all looks fine.

LI-7500 readings:
CO2 412ppm
H2O 471ppm
T 17.1C
P 101.9 kPa
SS 97 --> 98 after cleaning

LI7700 readings (sn TG1-0424 --> sn TG1-0424 clean --> sn TG1-0224):
CH4 1.97ppm --> 1.94 --> 1.92
RSSI 34 --> 70 --> 72

We left at 11:40.
