East Pond

We arrived at 13:20. it was clear, sunny, and warm. The water level was 60cm. There are some small (10-20cm) plants with small yellow flowers in the wetland.

I downloaded USB GHG and met data. The Licor GHG data still looks like it's been dropping out at night between midnight and 5-6am, even after Joe refilled the battery water last week.

Joe and Robert unhooked and checked all the batteries. Two were weak, so we took those home. This system sn BB-EP now has 4 batteries and will probably need a new set of batteries in the fall. The met and GHG data looked fine after power came back on.

There were many fine spiderwebs around the flux sensors. I didn't have alcohol and wasn't able to clean the 7700 thoroughly.

LI-7500 readings:
CO2 388ppm
H2O 650ppm
T 28.2C
P 102.2kPa
SS 94

LI7700 readings
CH4 1.97ppm
RSSI 57ppm --> 63ppm after cleaning

We left at 13:50. On our way out, we noticed the inlet pump was seriously gushing, so we closed it a bit.
