Spring 2022 Notes

• I have 2 wire snakes in Fairbanks. Blue & Brown. Send Brown to Nome and leave out there on spring trip.
• Bring out two pipe wrenches in March / June so that we can take apart the drill bit Sasha used in Fall of 2021.
• Need to add to the Teller 47 site visit to do list "DUMP PRECIP BUCKET EVERY VISIT"
• Need to measure the Teller Creek at a high flow in 2022 (So: May) a few times in order to be able to use the old rating curve with the new pressure transducers.

Replace top mast and anemometer

• Full replacement anemometer
  • potentially could reuse one from storage but will need:
    • propeller (need to order)
    • cable (fairbanks supplies)
    • right size cord grip (I'm sure this is found in my Fairbanks supplies... or the one that's currently broken... )
    • unistrut & 1" pipe & ubolts (try the square ones?)
    • nylock nuts
• new brown tarp
• bring out replacement card... could send new program that doesn't save out the soils data any more to increase storage...
• put soil moisture probe back in ground.
• I guess remove VATP from program to make the data record last longer.
• @Conex
  • Ladder (for anemometer fix)
• @Tools Required
  • 1/2" box wrench / nut driver
  • 5/16" nut driver

K1 Burn

• Should visit since I haven't heard from it.
• change out the SR50A transducer
• bring a thermistor for air temp (assuming there will be some damages)
• I guess, given that it isn't on the radio network any more I should expect something worse.
  • power cable to fix a chewed solar panel
  • coax in case that was chewed

K2 Met

• Station visit required
• Bring out desiccant for radiometers (loose)
• replace CR10X but change the watch battery on the logger to take out first.
• check on the wire rope left here so I can add fittings...

• No idea... need to review how I left things in 2019.
• Bringing a spare CR10X to this site, too.

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

• 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
