Summary: Regular data collection/cleaning, floating bucket is impeded by cattails

2024-12-04
Mayberry

Carlos and I arrived at 9:20 PST. It was sunny, cool, and still. The fog from the early morning had mostly burned off. The staff gauge read 55cm. The wetland is mostly brown now. We could hear sounds of hunting. We replaced the upper boardwalk on the tower (it was removed last time for storm prep).

Carlos cleaned flux and rad sensors. SWin had some black fur on it that he cleaned off. The reservoir was 1/2 full; he refilled it. I downloaded met, cam, and USB GHG data. I changed the eddy clock +1:20min from 9:32:30 to 9:33:50 to match the laptop time and restarted logging. I downloaded the miniDOT data and swapped its desiccant. The precip bucket looked clean.

The floating bucket is kind of propped up my cattail growing under it, but the water sensors are still all underwater for now. I want to trim the cattails down another time.

The Campbell water level sensor still needs a desiccant tube! I dropped it in the water at least a month ago but keep forgetting to bring a replacement.

I measured the surface water conductivity.
Surface, 1580uS, 9.1C

The 7500 read: -14pm CO2, 8.5mmol/m3 H2O, 13.2C, 101.7kPa, 50SS(probably dew)
7500 cleaned read: 536ppm CO2, 476mmol/m3 H2O, 13.7C, 102.4kPa, 100SS
7700 read: 2.9ppm CH4, 40RSSI – 71 after cleaning

We left at 9:45 PST. I started eating my lunch and apparently tricked Carlos into thinking it was near noon.
