Summary: Regular data collection/cleaning, sheep on the gravel road, changed eddy clock +1min, ants in 7550 box

East End

I arrived at 15:15 PDT. It was hot and muggy but ok in the shade of the tower with a breeze. There were sheep all along gravel road running north-south by the tower. I drove slowly through them on the way to and from the tower. The wetland plants are tall and green. The staff gauge read 31cm.

I downloaded met, camera, and USB GHG data. I cleaned flux and rad sensors. The wash reservoir was 2/3 full; I refilled it. I changed the eddy clock +45sec from 14:21:15 to 14:22:00 to match the laptop time and restarted logging afterwards.

There were many ants and their eggs in the 7550 box. I left the box open for a while, then tried to shoo as many out as possible using canned air. I left mothballs in the 7550 and met boxes.

The water level data had some NANs. I fixed its power plug which was a little loose. Keep an eye on this.

The 7500 read: 414ppm CO2, 819mmol/m3 H2O, 303.1C, 100.9kPa, 90SS -- 92 after cleaning
The 7700 read: 1.99ppm CH4, 40RSSI – 79 after cleaning

I left at 15:40 PDT.
