Gilbert Tract
2024-01-04

Dennis and I arrived at 15:23. It was clear and sunny but beginning to cool down and a breeze was picking up. It was close to low tide here but still ebbing. The water level was 42cm at 15:33.

Dennis cleaned the eddy sensors and the radiometers and made sure the tipping bucket was clean.
The 7500 read: 433.5ppm CO2, 408.4mmol/m3 H2O, 15.2C, 102.3kPa, 101.1SS
The 7700 read: 2.04ppm CH4, 66RSSI – 80.4 after cleaning
The wash reservoir was refilled by about half.

I collected the flux, met, camera and miniDot data. Lowering the water sensors and checking the CTD conductivity were on the list but I skipped/missed those. I think a floating boom might be useful for the water sensors.

We went to the channel and downloaded the flow data. This time the software asked for a clock reset (yes), pressure calibration (no) and warned that the firmware was old. I stopped logging, collected the data and restarted logging. We waited for about 5min to see if the real time data window would update but didn’t see that happen.

We left at 15:50
