11/19/2009 Arrived about 10:30am with Cove to setup the generator. Clear, cool, very light wind from the southwest. Late in the day very light wind from the north. Fields are beginning to flood. North part of our field is wet but the water has not percolated to the south end yet. Immediately next to our tower is still dry, but there is some water visible further out and slightly to the north. When we arrived the Campbell enclosure on the tower was wide open and there was evidence or rain from Tuesday on the equipment, but everything appeared to be in working order. The laptop seems to be off, with lid closed. Because of this no web cam photos were collected. Generator was set up along the road to the north of the tower. The power strip could not support the scroll pump so we had to run with the smaller diaphragm pump. When the LGR analyzer started up it was very cold (~4C). The water channel did not read initially and the other channels read high. Readings seem to begin to settle into more reasonable values as the analyzer warmed up. Adjusted bypass valve to bring pressure into good range. Returned about 2pm. LGR stats: 13:13, 1.930ppm, 6835.94ppm, 393.55ppm, 18.81C, 141.58Torr, 17.493usec, 10Hz I reset the laptop password to “pippo” and setup daily MD9 renaming of the CR1000 and CR23X files. I copied all data and images from the laptop and swapped cards on the CR1000. Separation between our tower and Franks tower at their original locations on the berm was 12.2 meters. |
