Summary: Regular data collection/cleaning, serviced water sensors, swapped LI-7500 for calibration

Mayberry

We arrived at 13:40. It was sunny and mild with clear skies and a bit of breeze. The water level was 50cm. I refilled the wash reservoir; it was 4/5 full.

Katrina collected water samples for Isabel at 12:50 PST. Sam cleaned the flux and rad sensors. We swapped 7500 for calibration: sn 75H-2150 came down, and sn 75H-2669 went up. I updated the configuration file, updated the pressure coefficients, and reset the 7550 box. I confirmed the USB data was logging.

I collected met, camera, USB (reusing the same USB stick), and miniDOT data. I had dropped the SD card reader in the mud at WP; the reader wasnâ€™t working at WP but it worked now at MB. Sam got in the water to get bubbles out of the fluorometer after we lowered the floating boom. We need new desiccants for the miniDOTs next time.

LI-7500 readings (sn 2150 dirty --> sn 2150 clean --> sn 2669)
CO2 398ppm --> 407 --> 410
H2O 530ppm --> 573 --> 567
T 26.0C --> 26 -->26.2
P 100.7kPa --> 101.0 --> 101.0
SS 94 --> 98 --> 103

LI7700 readings
CH4 1.93ppm --> 1.95ppm after cleaning
RSSI 60ppm --> 86ppm after cleaning

We left at 14:10.
