Summary: Regular data collection, redeployed dissolved oxygen probe, water level low

Arrived at 12:05. It was sunny and clear with no wind. The wetland was browning. There is still some green visible but most cattails are about halfway brown now. Water level is still low.

Refilled wash reservoir, it was half full.
Collected USB GHG data, collected met data, all looks good. Air pressure seems to be working right now. There are no free channels available and swapping it to a different channel would involve some rewriting of the program code, so left it where it is right now.

The camera pictures were collected to a USB drive. Direct connection with a laptop to the computer in the datalogger box through Ethernet did not work.

Redeployed Dissolved Oxygen probe sn DO-06 after calibration and testing in the lab. Was reading 81.47mV upon reconnect when exposed to air and dropped down to 60mV when dropped in the water. Seemed to be working fine. Since the water table was so low the probe was placed just above the ground to be fully immersed in the water.

Sam took spectral readings along the boardwalk to the north.
