Stuff to Pre-Ship

NGEE Container
- Salt packets:

To Do
- Find a picture of Teller SW and see what the charge controller looks like... Sunsaver 4.5

Broken Things to Look at
Trimble batteries
- Grab the batteries from the warm storage to charge
General
- Replace all CNR4 desiccant
- 2pcs Phillips screw driver
- small blue channel lock
- bubble level
- level all precip buckets
- torpedo level
- make a video at each site of current state
- camera
- download data
- computer
- 2pcs serial cable
- SC32A / MD485
- MicroUSB cable for Teller 47
Teller m47
- ---> Grab from UAF storage the two spare AT/RH to swap in.
- For later:
- Second data logger with air temp & tipping bucket
- red & black wire
- crimp ring connectors
- enclosure?
- 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.
- Second data logger with air temp & tipping bucket
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...
- Looking at a 2016 picture a sun saver charge controller is in there and replacement looks not difficult. Just rewiring the solar panel side... and given the battery voltage drop on logger I don't think the CC fried when the animal hit the solar panel.
- 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.
- log resistance of thermal conductivity probes instead of temperature.
- 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.
Council Grid
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.
- CNR4 knocked off level.
- 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.
- Snow Temps tipped a little.
- 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...
- anemometer 1" pipe broken off at threads.....
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.
