As planned, I installed one of the Tsoil pickleforks upside down (and the other normal).  The normal one had the thin, brown coating, the upside-down one was the thicker white epoxy.  I didn't record which was which channel.  However, looking at the data, it appears that the ".x" one is normal and the other is upside down.  I'll modify the config to reflect this arrangement.

Also, looking at the data, my guess is that the 10 and 20 cm Tsoil sensors are swapped.  The cables were labeled that 10cm was SN17 and 20cm was SN20.   I'll make this change as well.

What I don't know about is Qsoil,  10cm SN was 11, 20cm SN was 16.  The current profile makes it appear that the current ID assignments are correct in the data, but I'll have to check this.

Some more notes about this installation:

  • dug a small trench to 10cm, took core sample (to be used as an offset check, though the EC-5 won't have settled well).  Depth of this sample approximately 10-13cm.  Core taken 11:12.
  • continued digging to 20cm, took another core sample.  Depth of this sample approximately 20-23cm.  Core taken 11:29.
  • cleaned one side wall in narrow end of trench and installed T/Q probes at 20cm and 10cm.  Note that we only had a big screwdriver, so the pilot hole for the single Ts were larger than needed.  Thus, these may not be well coupled to the soil (nevertheless, the data look okay).  Used a butter knife for a pilot hole for the 20cm EC5.  The 10cm EC5 didn't need one.
  • took a third core sample at a nearby plot.  Depth of this sample approximately 2-5cm.  Core taken 11:57.  Installed EC5 and HFT at about 5cm in this hole.
  • removed a "brownie" in this same plot.  Used a butter knife to cut a slot and installed the TP01.  Replaced the brownie.
  • cut a nearby slot for a picklefork.  Installed this one in a normal orientation.
  • cut a second slot for the second picklefork, installed upside-down (eyeballed to the correct depth).  Note some cracking in this part of the soil.

All this done between (approximately) 10:30-13:00 yesterday (20 Feb).  (Yes, it took a while to work down to 20cm.)

Brought soil cores back to the lab and weighed (wet) about 4–5 hours after the sample was taken (a bit long, so some drying might have occurred).  Couldn't find the oven, so just drying open in the lab.  Note that there were some water drops on the lid of (I think) the 20cm sample.  Thus, it definitely will be drier.  (I realized that I could have measured this by 1. weighing a piece of paper towel 2. wiping off the moisture with the towel 3. weighing the "wet" towel, but I didn't do this.  Just for fun, I'll try to simulate this when I'm next in the lab.)  I'll start a separate entry on processing of these cores.
