East End
2014-09-10

I arrived with Sara about 1pm. It was clear and hot with no wind. The wetland continues to fill in. There were quite a few ducks about.

We calibrated the 7700. We had to disconnect the Ethernet cable from the CR1000 and made sure it was connected and working when we were done. The offsets were bigger than usual at about 80ppb. It seemed to take longer to settle than I remember, but maybe that was just standing around in the heat.

The 7700 read: 2.0ppm, 82RSSI after cleaning and before cal.

Sara took water samples
