Summary: everything OK, Emily took water samples

Arrived at the site around 1pm local time. A slight breeze compared with the Twitchell Island sites, although still quite warm.

All looked well at the flux tower. We downloaded flux and met data as well as the digital camera photos. LI-7700 RSSI was 41 upon arrival, and 87 after cleaning. Emily Gilson took an increased number of replicates (5 at each spatial location in the wetland) of water samples for CO2 & CH4 analysis back in the lab. I gave the solar panels a wash while waiting for Emily to finish sampling.

CH4 = 2.0 ppm
CO2 = 392 ppm
H2O = 670 mmol/m3
SOS = 350 m/s

Joe moved the portable tower while we were finishing up at the permanent site. All’s well with that tower too. LI-7700 RSSI was 50 after moving the sensor, we forced it to wash itself and it bumped up to 57. We downloaded flux data.

CH4 = 1.98 ppm
CO2 = 382 ppm
H2O = 600 mmol/m3
SOS = 350 m/s
