Summary: Regular data collection/cleaning, high water level

2024-04-23
East End

I arrived at 15:30 PST (16:30 PDT). It was mostly cloudy and breezy. The water level has come up a lot. Another 10cm and it might touch the bottom boardwalk. The staff gauge read 83cm. The gravel road leading up the tower has been cleared by sheep/goats. The wetland edges have green tules well above the litter layer, but the cattail in front of the tower are barely showing through the litter.

I downloaded met, cam, USB GHG, and miniDOT data. Nighttime PARout data has been messy recently. I redid the datalogger wiring, but it seemed fine. The sensor and cables also looked ok. I changed the water level desiccant but the miniDOT desiccant was still fine.

The 7500 read: 430ppm CO2, 492mmol/m3 H2O, 21.2C, 101.3kPa, 95SS – 96 after cleaning
The 7700 read: 2.0ppm CH4, 39RSSI – 77 after cleaning

The handheld conductivity probe had run out of batteries earlier today during our Los Medanos field trip at Gilbert Tract, so no surface water conductivity measurements today.

I left at 16:00 PST (17:00 PDT).
