Sherman Wetland: 2018-04-05 09:20:00 (DOY 95)
Author: Daphne Szutu
Others: Elke, Kyle

Summary: Regular data collection/cleaning, met CR1000 was unresponsive

2018-04-05
Sherman Wetland

We arrived at 9:20. It was very windy, cool, and overcast. There are new cattail coming up around the tower.
Elke refilled the wash reservoir; it was 1/5 full. Kyle cleaned the rad and flux sensors.

The met datalogger was not running even though it was getting 12.5V: I couldn’t connect to it from the laptop, and we did not hear the multiplexer clocking through ports. I power-cycled the datalogger, but nothing changed. I removed the CF card and the CF card interface and reset the 12V power strip. The logger started back up so I downloaded the met data, which stopped on 2018-03-29 at 6:30.

The met data seemed fine and we didn’t see anything obvious that points to why the datalogger froze. Joe suspects it’s a hang-up from the SDI-12 sensors and we should update the CR1000 OS. The camera CF card was also corrupted and we weren’t able to recover any photos from the past two weeks. I collected USB GHG data.

LI-7500 readings:
CO2 410.7ppm
H2O 266ppm
T 14.5C
P 101.9 kPa
SS 101 --> 102 after cleaning

LI7700 readings:
CH4 1.95ppm
RSSI 47 --> 79 after cleaning

We left at 9:50.
