2021 NGEE Nome June Trip

Rough plan

• Join ORNL / Sigrid team partway through

PRs

• XX Battery
• XX Shipping
• tracker & restart plan.

People

• Alert Chad & Crystal
  • Need lock key

Stuff to Pre-Ship

• Any gear
• Personal Gear

NGEE Container

• Salt packets:
  • They should be in Box 6 (long black box with green handles). the grain scale should be adequate for this though. I would bring a few, just in case...

UAF NW Campus

• Grab Trimble batteries to recharge from NGEE storage closet
• Grab key from Rick Anderson
• Radio setup
• anti corrosion goo

Broken Things to Look at

Teller m47

• Grab from UAF storage the two spare AT/RH to swap in.

Teller SW

This site is about 10 minutes off the road next to the Teller Bottom Site. Rubber Boots would be good for the hike. Hiking boots are fine, too. The wet spots mostly can be avoided with a bit of extra walking.

• Need a battery, solar panel, and CR800 w/ program to replace animal damaged hardware.
  • worst case could grab a battery from teller bottom...
• Make a discharge measurement & manually measure stage

Teller Bottom

• Heat Flux Plate... Loose Wires?
• Measure how far VATP is sticking out of the ground
• Grab the missing gap of data off logger.

Teller Top

• HMP155 needs replacing
• Level CNR4
• Level Rain Gage
• Program Changes:
  • log resistance of thermal conductivity probes instead of temperature.
    • Maybe for all thermistors...
    • Related, make sure there are fixed resistors being logged
  • Maybe change the file saving from filling the memory as is done at present.
  • Change output of snow temperature profile to go 10/5 to 6/5
  • Increase the mV range of the top soil heat flux plate to reduce occasional over-ranging in summer / early fall.
• Measure how far VATP is sticking out of the ground
• add a couple precision resistors to the thermistor multiplexer.
• Tools:
  • Computer
  • Serial cable
  • large channel lock for HMP155 replacement
  • electrical tape for HMP155 replacement
  • torpedo level
  • bubble level
  • large #2 phillips for CNR4 leveling
  • small #2 phillips for CNR4
  • grease for anticorrosion
  • 5/16" nut driver
  • Bring up a couple rocks to help level Rain Gage
    • I remember one end being bottomed out or something.

Kougarok m64

• LOTS of broken

Kougarok 10m tower

• Download Data over radio

Kougarok Burn Site

• Download Data over radio

Stretch Goals

If timing works out:

Check out Radio base station at NW Campus

• Same building as NGEE warm storage (I believe). base is in an IT closet.
• Computer went offline in March and I might just replace it.

Drive up and check on first radio repeater atop Anvil Mountain

• 10-15 minute drive, 2 minute walk to a site on top of Anvil Mountain. Radio still works but radio to logger dongle died over winter.
