Seward Peninsula

2018 NGEE Nome June Trip

• 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.
• 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
• Measure Creek Flow
• Re-level radiometers
• Measure thermistors at Teller Bottom and add them to fieldbook.
  • 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
• Koug M64 Ngee tipping bucket stand is 1" aluminum pipe (verified by photo)
• Teller Bottom tipping bucket stands: 3/4" aluminum pipe (it appears)
• 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. It seemed to work great... though we haven't worked up the data...

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

Teller bottom precip bucket swap

• small csi phillips
• desiccant pack
• 2 red butt splices
• toggle bolts
• 5/16" nut driver
• 1/2" nut driver / wrench for ubolts

• wire cutter

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.
