Summary: Standard fieldwork, collected data including z-cams - previous Floor CR1000 card failed to format, tram okay, CO2 profile pump broken
| Tonzi 2013-07-11 I arrived about 10:30 with Siyan. It was clear and hot with a breeze from the south southwest. Things look very dry with some trees turning brown and looking dead. The pond is as low as I have ever seen it. The tram was running just fine. The pump for the CO2 profile system had blown its diaphragm. I have a spare, but I should order a couple more and up one in the field for a quick swap. I pulled the old pump, unplugged the LI820 and unplugged the CR10x. I meant to bring two IRGAs to swap for calibration, but I forgot them in the lab. I serviced the z-cams and check their clocks before swapping cards. Camera 1 and 2 seem to be off 4 to 8 minutes, z-cam three seems to be within a minute. Ill unmounts them and reset the clocks next time. I also checked the times on the data loggers that control the cameras. The CR200 on z-cam 3 was 10 minutes fast. At 10:46 I reset it to 10:35. The CR10x on z-cams 1 and 2 was 18 minutes slow. At 10:56 I reset it to 11:14. I also unpowered the CR10X briefly while I removed the Licor PAR sensor that was idle in that box. I collected all data. The Floor CR1000 card failed to format, but data was still collected by winflux. I checked the card, found no problems and when I reinserted it in the CR1000 it formatted in 2 minutes working just fine. |
