2011-06-21 I arrived about 11am with Jose. It was clear, sunny and hot with almost no wind. There was just a breath of breeze from the south. The pepper weed was in full bloom and stood about mid-thigh in the field and waist high inside the cow fence. From the bridge on the way home, the north ditch was damp but no water visible and the south ditch had water in it, which is unusual. I collected data. I did a full collection from the soil co2 system. The clock on that data logger was way off. Various times: Cell Phone 2011-06-21 11:14:00 Computer 2011-06-21 10:15:00 Data logger 1964-01-03 01:22:53 I started the data collection when the data logger’s clock read 01:24:00. Times on the data collected were unintelligible. I could not recreate data order. I swapped the LI7500. Sn 0073 came off and sn 0042 went on. The funnel on top of the rain bucket had fallen off. I found by the foot of the tower. Probably knocked off by a bird. I took photos of the diffuse PAR system. We did the moisture point probes. The last reading looked strange with the location number (4) blinking, maybe saturated? East sn ending in DAA1 12.7, 36.8, 36.6, 11.1 12.4, 36.5, 36.8, 11.1 North sn ending in 072 22.9, 33.8, 36.3, 11.1 22.9, 34.1, 41.9, 11.1 West 12.7, 25.8, 36.3, 4.4 13.5, 26.1, 36.8, 96.7 And we read the wells. The west well seemed to have a layer of scum/debris on the surface of the water that fouled the well depth sensor. All measurements from the top of the pipe using the black fitting that comes with the depth sensor. East 3.1ft, west 3.0, north 3.85 I reinstalled soil heat flux plate #2 Jose did the LI2000 and spectrum, clip plots and digital photos. |
