Summary: Regular data collection/cleaning, cold and breezy

Hill Slough

Carlos and I arrived at 10:05 PST. It was clear and cold with a cold breeze and a few wispy clouds. Water level was high-ish and the staff gauge read 5.68ft at 10:15 PST.

We sampled water from the porewater sipper to measure for conductivity later. It will be stored in the fridge for now.

When we arrived, there was a bird watcher with a huge lens parked near our usual spot, but he had left by the time we wrapped up so I didn't get a chance to ask what cool birds he had seen.

I downloaded met, cam, and USB GHG data. Carlos cleaned rad and flux sensors and topped off the wash reservoir. I changed the eddy clock +45sec from 10:12:25 to 10:13:10 and restarted logging.

The 7500 read: 420ppm CO2, 211mmol/m3 H2O, 10.6C, 102.0kPa, 101SS -- 102 after cleaning
The 7700 read: 1.97ppm CH4, 39RSSI – 70RSSI after cleaning

We left at 10:20 PST.
