Summary: Regular surface and porewater monthly collection

Joe, Daphne and I arrived at Mayberry at 9:14 am. We set up the new picnic table before they drove to Tonzi-Vaira for regular field work.

It was a hot sunny day with little wind. I collected surface waters at the channels in front and to the west of the tower as well as in the inlet and outlet locations. Additionally, I sampled porewaters at the 0.5 and 0.7 footprint locations covered by vegetation. At these sites the water level was at around -10 cm.

Readings at the Tower:
Conductivity: 6.60 mS
Salinity: 3.99 ppt
pH: 8.2
DO: 6.36 mg/L

The readings at the tower were similar to those at the west channel, however porewaters had higher salinity (5.5 ppt), lower pH (6.5), and lower DO (1.5 mg/L).

I used a new probe (YSI Quatro) to measure DO and to start monitoring it in the porewaters. For this reason, I buried a miniDOT sensor at -30 cm depth at the 0.5 footprint location (38.049846Â°, -121.765356Â°). I will download miniDOT data during the next field visit and compare it with the values measured by the YSI probe.

Joe and Daphne returned form Tonzi at 15:45 pm and we all drove to the most western location of the EC footprint, followed by the outlet and inlet locations where we collected surface water samples.
