Summary: Regular data collection, cut back willow, ants in both logger boxes.

Arrived at 9:45. Sunny, windy, mostly clear skies, but hazy in the distance. Wetland has greened up quite a bit. Lots of tule and cattail coming through the accumulated dead biomass, but there are still some spots that are mostly brown.

The water level looked normal and the inlet pump was running.

Filled the LI7700 wash water reservoir, but it was still almost full. Cleaned the LI7500 and LI7700.
Collected USB GHG data, collected met data from CR1000, collected camera pictures. DO upper was reading zero.

There were quite a few ants in both boxes, the CR1000 datalogger box and the LI7550 box. It looked like they were trying to build a nest, we saw a pile of eggs. We tried to clean the ants out and left both boxes open when we left for the time we were working on Alfalfa and East End. We came back in the afternoon at 13:05 to close the lids of both boxes. At that point most of the ants had disappeared, but many have probably hidden behind the dataloggers. The ant traps in both boxes were clogged up. Unclogged them, but we should probably bring new ant traps next time.

Kyle cut back the willow that was (possibly) shading our radiation sensors in the morning. Cut down some really big branches, but the main stem of the willow is still there. But most of the branches that were shading the radiation sensors have been removed.

LI7500 readings:
CO2 408.91
H2O 597.0
T 20.21
P 101.23
SS 98.68 -> 102.57 after cleaning
LI7700 readings:
CH4: 1.95
RSSI: 62.8 -> 80.9 after cleaning
