I arrived about 12:30 with Sara and Carina. It was sunny and hot with a strong breeze from the west. The field looks drying than I ever remember seeing it. However there seems to be moisture just below the surface and weeds and rice are coming up in a green haze. There were four people there walking to field looking for archeological artifacts.

I installed a soil heat flux plate (sn 00243) to replace the one cut off by a tractor. We also found and staked up the three water temperature thermocouples a few cm about the ground surface.

I measured the well. The pipe extends 27cm above the ground and the well was dry at 76cm below the top of the pipe (39cm below ground). If the field is still dry next week we should probably re-dig the well.

We collected all the data.

The LI7700 RSSI was 29. After cleaning it was 72.

I talked to Jim on the morning of 06-08 and he said the field may stay dry for a week and a half yet.
