2021 NGEE Nome June Trip

Pre-Trip Electronics Checking

• Sat phone call to cell phone
• check operation of the inReach
• laptop batteries topped off
• camera batteries topped off
• Trimble GPS batteries

Rough plan

• Join ORNL / Sigrid team partway through

PRs

• XX Battery
• XX Shipping
• tracker & restart plan.
• XX UAF NW Campus conex annual fee

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

General

• Replace all CNR4 desiccant
• level all precip buckets

Teller m47

• ---> Grab from UAF storage the two spare AT/RH to swap in.
• Ship from Fairbanks a cross arm bracket and more pipe to better level the Radiometer which is off kilter.... or unistrut clamps actually plus a local purchase.
• For later:
  • Second data logger with air temp & tipping bucket
    • red & black wire
    • crimp ring connectors
    • enclosure?

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 at least one discharge measurement & manually measure stage

Teller Bottom

• Heat Flux Plate... Loose Wires?
  • The one labeled upper is first on the multiplexer.
  • The one labeled lower is second on the multiplexer.
  • in the parameters csv file.
• Measure how far VATP is sticking out of the ground
• Grab the missing gap of data off logger.
• add a resistor to the thermistor multiplexer
• 10cm soil moisture was reading zero in 2020 so loose wire to possibly discover.
• level CNR4
• level rain gauge

Teller Top

• HMP155 needs replacing
• Level CNR4
• Level Rain Gage
• bring out resistors for multiplexer.
• Lump snow depth is sort of knocked over. (Ken picture fall 2020)
  • bring from Fairbanks another screw in anchor
  • More guy wire
  • anchor
• 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
• Temperature Profile destroyed?... Late March 2020.
• Anemometer...
  • 1/2 depth unistrut (re-review pictures but look to have in the uaf conex)
  • 4 pcs square ubolts
  • compass
  • ladder from uaf storage

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.
• Optional... it's working great again... may have been network issue OIT corrected.

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.

Notes from Ken's Pictures

• Teller 47
  • CNR4 knocked off level.
    • Check supplies in nome conex. Otherwise, bring out Unistrut / pipe to make things sturdier.
• Teller SW
  • Solar panel gone & Battery dead.
  • Bring out a pack frame for battery retrieval.
  • and NRS Straps....

• Teller Top
  • Snow Temps tipped a little.
    • Measure and then can estimate current heights?
  • lump snow depth either bent over or pushed.... can solve with more guy wires I'm guessing.

• NGEE Kougarok
  • anemometer 1" pipe broken off at threads.....
    • could potentially fixed with ohhh. 2 1/2 channel unistruts & those square ubolts in my Fairbanks stock. plus one of those short 1" sections of pipe.
    • I think we need a new propeller here and who knows what else.
  • Ahh yes, pictures shows the soil temperature probe was chewed...

Post Trip

• In the subsurface data processing add the thermistor air temperature.

/var/site/uaf_sp/teller_bottom_soil/config/teller_bottom_subsurface_params-01_78.csv
same for all the soil moisture probes... here 5cm  to be added to the grouped output csv.
