Summary: Regular data collection/cleaning, set miniDOT clock

2024-09-26
Hill Slough

Carlos and I arrived at 14:35 PST. It was warm with a cool breeze. The suspicious van was parked just off of our parking spot again, with the windshield covered and the side door open. Some guy wearing just shorts was sitting inside. We took our backpacks and made sure to lock the car door.

The staff gauge read 4.6ft at 14:57 PST and the water level was on the lower end, with some higher spots north of the tower exposed. I downloaded met, cam, and USB GHG data. Carlos cleaned flux and rad sensors, cleaned out the rain bucket, and topped off the wash reservoir.

The 7500 read: 413ppm CO2, 690mmol/m3 H2O, 29.6C, 101.2kPa, 102SS - 103 after cleaning
The 7700 read: 1.98ppm CH4, 63RSSI - 87 after cleaning

I measured the porewater and surface water conductivity.
Porewater, 7.71mS, 24.6C
Surface, 5.88mS, 26.8C

At the channel, I downloaded the miniDOT data, swapped its desiccant, and set its clock and connecting the laptop to my cell phone hotspot. The time error for miniDOT sn 931528 was +1628 seconds (+27.1 minutes).

We left at 15:10 PST.
