  • Messed around with datalogger wiring, but was not able to restore measurements of soil sensors.

Mar 21, 2012

Made a quick trip up to try to fix soil moisture datalogging again. Still having trouble identifying the problem.

  • Excavated snow around base of forest datalogger post and checked wires.
  • Retaped some chewed (lightly chewed) wires and tried to put more slack in them - didn't seem to do much though.
  • Disconnected treatment IR radiometer, and forest Vaisala (not sure if this will help or not, but these sensors are malfunctioning anyways.)
  • When I left all sensors were working, though sometimes intermittently it seemed.
  • Took a snow sample from the board (2 cores, 37cm depth).

Mar 12, 2012

  • Sampled all inlets
  • Measured SWE in all plots (3 measurements each)
  • The bad soil profile data problem returned, so I excavated the snow at the post and left everything uncovered. There are some chewed up wires there (since retaped) but not sure if this is where the problem is or not. All soil moisture sensors are failing to read, not just the ones with chewed wires. Hopefully this will keep the data coming in for a while.

Mar 8, 2012

Noticed soil profiles were not working (all data was -6999) yesterday, went up to fix this.

  • Fixed one loose wire on MUX3 (Sentek sensor profile 9)
  • There seems to be some loose wiring at the base of the Forest1 datalogger post, but it is difficult to identify. Excavating the snow and adjusting the wire caging seemed to help.

  • Rewrote and sent a datalogger program to Forest1 datalogger. Program includes sentek sensors and new CS-616s in measurements and final storage table (averages).
  • Sent at ~4pm after downloading all data and archiving it
  • resent at 12am (9th) - doesn't appear to be sending the program, probably because the radio is turning off.

Jan 4, 2012

  • Sampled all inlets
  • SWE measurements in plot 1, 2, 3, 4 (4 measurements each)
  • Rewired Sentek sensors (12V power and Gnd are now on the terminal strips with the 616's)

  • 9:15am - Sent new program (v5) to Forest datalogger that includes profiles 6 and 8.

  • Added another 50 feet of rope, but there is still more needed below that.

25 Jan, 2010

  • Downloaded data from both dataloggers
  • Reversed wiring for downward looking PAR - should be working now.
  • Changed REBS negative correction factor to a negative value in Met1 EDLOG program.
