Summary: Field drained but still wet. Camera acting funny. Data collection.

We arrived at 11:06am. It was still overcast and the field was drained but still very wet—too wet to walk in. The reservoir was half empty so we refilled it. The camera had only taken 3 days of photos. There were no clear indications of loss of power when we got there—not sure what is going on with that camera. There were water droplets on the 7500 and numbers looked better after cleaning. Housen and Ana cleaned sensors and I downloaded data.
