Summary: Regular site visit. All well. Took additional soil samples in supposed low carbon site.

East End Wetland
2014-02-05

We arrived about 12:45 PST. There was a full high altitude cloud cover and it was cool with a very light breeze. The channels and ponds are full of water, but the main vegetation shelves remain dry. In addition to the boardwalk out to our tower, there are sampling boardwalks constructed in our check and the two adjacent checks to the north and south. Go Wyatt.

We downloaded data and cleaned the flux and radiation instruments.

7500 readings:
CO2 = 16.8 mmol m-3 (17.1 after cleaning)
H2O = 408 mmol m-3 (same after cleaning)
Diag: 249 (same after cleaning)
t = 16 C
p = 102.1 kPa

7700 readings:
CH4: 1.95 ppm (same after cleaning)
RSSI: 49% (75% after cleaning)
Topped off the reservoir.

MET looked good.

After checking the tower, Sara and I mosied to the check directly to the south of the permanent tower to take additional soil samples. None of the possible portable tower locations we sampled in December seemed to have as low of soil carbon content as indicated on the map, so we decided to sample this additional location which appeared to have low soil carbon. We took 10 samples in the same format as in December along with GPS locations.
