Summary: Regular data collection/cleaning, very windy

2023-04-11
Hill Slough

I arrived at 16:45 PDT. It was near low tide and the water level was below the staff gauge. You can see where some of the new channels are forming in the landscape. It was very windy and mostly sunny with some cirrus clouds.

The EXO in the channel is due for calibration but we’re still waiting for YSI to ship the conductivity/temp sensor. I’d like to install that new sensor at the same time I’m doing all of the calibrations. Maybe we’ll receive it at the end of the month.

I collected met, cam, and USB GHG data. The GHG data looked complete in the last week. Not sure what was wrong before that caused us to lose ~3 days of flux data. I cleaned flux and rad sensors and topped off the wash reservoir.

The 7500 read: 413ppm CO2, 548mmol/m3 H2O, 19.0C, 101.8kPa, 101SS—102 after cleaning
The 7700 read: 1.95ppm CH4, 45RSSI-- 70 after cleaning

I left at 17:05 PDT.
