Summary: Ameriflux to take down later today, standard data collection, grass has grown a lot, tested radio link to pond, collected pond data.

2017-04-24

I arrived about 10:00 with Siyan. It was cool and mostly sunny. The grass has grown a lot since last time. There were puddles on the road.

Ameriflux is supposed to take down their equipment today but they did not arrive while we were still at the site. We did the standard data collection including the new set of eddy equipment which we left running. Siyan did clip plots, spectral and veg height.

I set up a CR10x with a Campbell radio on a 10ft pole on a fence post at the northeast corner of the cow fence. We tested the radio link to the pond. At the pond I put a radio on another 10ft pole and was able to make a connection to the CR10x we left at the tower site. I need to buy some extension cables for the radio antennas then maybe we can get the radio link set up.

The pond level was 22.04ft. The water is very clear and we saw a big fish hanging out near the staff gauge.

Veg Height (cm): Tape measure from ground to top of plant - Outside fenced area - grazed
