Summary: Water on the field, swapped HMP60 fan, standard data collection

I arrived at 10:00am. It was cool with a thin overcast and a breeze from the southwest. There were puddles of water on the field. I talked with a fieldworker that stopped by who asked if the water was okay. I told him shallow water was okay.

Some of the CSI TDRs probes are reporting -9999 due to the water on the field.

The 7500 read: 492.6ppm CO2, 487.9mmol/m3 H2O, 8.59C, 101.8, 86.5SS
The 7700 read: 3.01ppm CH4, 40.0RSSI -2.93ppm CH4, 71.2RSSI after cleaning
The wash reservoir was 3/4 full, but I did not have water with me. I thought about using the spray tank water but it look a little dirty and I think the remaining water will last.

The HMP60 fan was dead. It was a 12V fan. I replaced it with a 24V fan and moved its power cable to the 24V power bus.

Tyler was out later to look at their equipment.
