To Buy

  • Step ladder for teller bottom
  • Bring out a replacement memory card for the Teller Bottom CFM module

General

  • 2 Trimble Yellow batteries left in NW Campus Warm Storage

Seward Peninsula

2019 NGEE Nome March Trip

2019 NGEE Nome June Trip

  • SR50A transducer replacement (fall activity)
  • (2019) bring out one step stool to level teller bottom radiometer.
  • (2019) bring out tap, die, drill, drill bit, screw for teller bottom radiometer.
    • screw...
  • also replace cnr4 desiccant since the unit didn't look like it was sealing right with this missing screw.
  • Bring out additional desiccant? for box
  • Teller SW desiccant replacement
  • (2019) Redrill hole for C1 Grid temperature probe
    • what is needed for this?
  • Measure Creek Flow
    • salt slug, n=2 samples of 50g / known volume of water
  • Re-level radiometers
  • polish radiometer domes
  • Measure thermistors resistances at Teller Bottom and add them to fieldbook.
    • There are a couple with a 0.5C offset at spring freezing point so I think they may be failing and or something...
    • Related: I'm wondering if the delay between measurements should be increased for the thermistor measurements.
    • Also related: perhaps add a second string up at teller top?
    • sort of some additional homework is that I saw instability in a number of thermistors when measuring up top. I suspect but haven't verified that this instability is an indicator for the wonky temperatures seen in the data but need to confirm.
  • 6/11/2018 In Fairbanks... down in 106 / the basement there is a box of 12" nails. Would be good to grab three for the Teller SW solar panel tripod
  • I should do some experiments with the thermal conductivity thermistors in office/lab to see if I can reduce the noisiness.
  • finish surveying vegetation plots

Kougarok

  • bring out a serial cable for box (removed it in fall 2018)
  • get a compass reading on anemometer
    • leave a compass in the box

Teller SW Flow

  • left a metal meter stick at the site
  • fieldbook
  • YSI conductivity meter
    • manual
  • electrical tape

Radiation Level:

  • step ladder
  • a bit of wood to provide better base for step ladder
  • phillips screwdriver for level


Radiation Desiccant Swap:

  • Step ladder
  • small CSI phillips
  • K&Z desiccant pack
  • anti-corrosion goo

Teller Top Soil Temperatures

  • Volt meter
  • fieldbook
    • learned but need to confirm that the thermistors with a capacitance are ones that are unstable and failing.

Utqiagvik

  • Intensive Site A HMP155 failed (3.5m)
  • Intensive Site B HMP155 failed (1.4m)
  • Intensive Site C HMP155 failed
  • need to replace the network cable running from the computer to the network switch. It cuts out with minimal bumping.... but station is finally back online!!!
  • Site A SR50A transducers have failed
  • some subsurface items are beginning to fail.
  • bring up clear tape and a biz card to label the computer
  • bring up the nuc plate and wood screws and other screw packet to mount nuc to wall
