From about 1330-1630 installed this station.  Of note:

  • wind observer "north" transducer to the NE
  • CSAT boom approximately to the NW (about like bao)
  • 20cm Tsoil&Qsoil are IDs 24 and 14, respectively
  • 10cm Tsoil&Qsoil are IDs 25 and 15, respectively
  • epoxy-coated picklefork is installed upside-down (coming in as Tsoil); brown-coated pickleform is normal (coming in as Tsoil_x)
  • had trouble getting Xbees to receive – mote RF power likely set too low; ended up putting "base mote" on rad stand, along with the other 3 (1 rad/2 soil) motes.
  • soil motes are ID4 (normal) & 10 (extended)
  • took a soil sample at about 1430 from 2–5cm (labeled "1 (0-3cm)"), but forgot to weigh it!  I'll try my paper towel trick tomorrow, first thing.
  • several mast issues (including some that will require a second visit).  Kurt will update.
  • Kurt reported that DC power from his AC supply was low – Vbatt has been going down slowly.  We'll keep an eye on it.

TODOs:

  • take photos
  • get GPS location
  • shoot boom angles

 

  • No labels

    Thanks, guys, for your hard work today.

    Started processing of the one soil core this morning.  The clod was one intact cylinder, so the surface area was minimal, it was stored in the pickup in the high-bay overnight, so it wasn't <too> warm, there wasn't any moisture condensed on the lid, and the clod itself was still "sticky".  Thus, I don't think it dried out very much, though some loss is expected.

    P.S. As it turns out, this gravimetric sample turned out to be 9% more than the EC-5 reading.  This may be due to the difference in measurement height (2–5 vs 5cm) – there was water running along the surface within 3m of this plot, so the top of the soil definitely was wet.

    Next soil sample might use the 1cm rings on the corer to better define the sample depth.
