2012-03-21 I arrived about 12 noon with Siyan. It was warm and sunny with a light breeze. A few trees here have leaves, but most don’t. The ground is still wet and the grass is green. Stephen followed us over for a look at Tonzi. Laurie and a student were there taking soil cores. Martin and a colleague were that to do 3D Lidar scanning of trees. The tram was stopped again having derailed. I replaced its battery and the cotter pin in its north drive wheel with a 4-40 bolt. I found a loose portion of the track where the tram derailed. I filed do a lip in the rail and tightened the bolts. The tram ran a couple times before we left. I service the z-cams. I copied data from the new soil CO2 profile. For some strange reason only the first of the three channels was being read and recorded. I changed the program from using reps to read the channels to three read instructions for both the CO2 and TCs. This seemed to work. The cow fence around the tower has a couple of loose spots on the west side that need fixing. |
