Mayberry

Arman and I arrived at 11:20 PST. It was clear sunny and cool with little to no wind. The main road has been graded and farmers were moving hay under the bridge. The wet land is mostly brown. The water level was 20cm

I collected the flux, met and camera data. I was having trouble with the cable connections until I remembered which USB port on the laptop was bad. Arman lowered the eddy sensors for cleaning and installing a HMP45. The locking pin was missing – we put in a 1/4-20 bolt when we returned it to the operational position.
The 7500 read: 443.7ppm CO2, 619.7mmol/m3 H2O, 17.0C, 100.8kPa, 105.4SS
The 7700 read: 2.1ppm CH4, 46RSSI – 73 after cleaning
The wash reservoir was only about a third low – refilled despite the wasps in the box.

We removed the HMP155 cable and installed HMP45 sn D4420028. After collection the met data I uploaded a new met program with the correct offset for the HMP45 (-40). All seemed well.

We collected the miniDot data and swapped its desiccant.

We tried to get some water from the sippers but no luck. A couple seem to be sucking air. I cut the chewed end of the red one but it was still pulling mostly air.

I put some moth balls in the met box. There were some ants around but I don’t think they were in the box yet.

We left at 12:20
