At Gary's inquiry, I have plotted Qsoil from tnw09 for the last 20 days.  This sensor has read mostly negative values consistently, but clearly is responding, for example to a precip event 17 days ago.  We should check the sensor cable connection at this site.  (All of the Wisard boards are plugged directly into the mote boxes, so this connector is easily accessible.)  Qsoils should be the red Wisard board.  

In any case, we should take regular soil cores at this site (of course, we should take them at every site), to be able to create an in-situ calibration.
