To Buy
- Step ladder for teller bottom
Seward Peninsula
- SR50A transducer replacement (fall activity)
- bring out one step stool to level teller bottom radiometer.
- 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
- Redrill hole for C1 Grid temperature probe
- what is needed for this?
- Measure Creek Flow
- salt slug, n=6 samples of 100g
- Re-level radiometers
- 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.
Teller SW Flow
- cloth tape
- left a small cloth tape at the site
- metal meter stick or folding tape
- left a metal meter stick at the site
- flow tracker
- fieldbook
- YSI conductivity meter
- manual
- electrical tape
- We (Nathan and I) set up a reach to use for salt slug method discharge estimates.
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 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
