• Step ladder for teller bottom
• 12 volt Trimble cable

Seward Peninsula

2019 NGEE Nome March Trip

• 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

Kougarok

• bring out a serial cable for box (removed it in fall 2018)
• get a compass reading on anemometer
  • leave a compass in the box

Teller SW Flow

• left a metal meter stick at the site
• fieldbook
• YSI conductivity meter
  • manual
• electrical tape

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 A HMP155 failed (3.5m)
• Intensive Site B HMP155 failed (1.4m)
• 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
