2022 NGEE Nome May Trip

Purpose:

Spring station data download and creek measurement.

Trip Summary and Loose Ends

• Teller Bottom Soil Moisture sensor need a bit of attention. No SDI 12 action.
• Buy and bring out a short step ladder for Teller Bottom CNR4
• Teller IS2 charge controller doesn't look to be working (confirmed looking at March data download).

Nome Conex Instrument Inventory (May 2022 Edition)

• Left 2 HMP155s in Nome Conex
• Left 1 SR50A in Nome Conex
• Left 1 BP Sensor in Nome Conex
• Left 2 anemometers in Nome Conext

Teller bottom 2022-05-20

• Problem files
  • Micromet110.dat
  • Mm112
• Anemometer:
  • With yellow boat compass east /west line is at 294 magnetic. From east looking west at anemometer box

Teller SW

• Teller creek is probably highest observed discharge
• Teller sw could use one serial cable

Teller IS2 Snow

• Need a base plate for 4x4 to keep it from sinking further into muck. That turns out to be the source/reason for the lean.
• Limited Lean 5/22/22 by pounding in rebar with guy wire anchor. Could use rebar cap from storage for it (or from Fairbanks)
• Also on 5/22/22: Verified voltage of solar panel and battery. Charge controller needs replacement

Kougarok m64

• Looking east to west anemometer box is at 273 degrees magnetic
• Snipped the pressure vent tube but thinking I should return with something more. Like pvc pipe going to ground so there is even less chance of clogging. Like could add the T sections of drill holes in pipe for venting

Kg is5 snow

• Battery box lid blew away. Otherwise good
• Could use a sticky hook to hold serial cables up inside these boxes

KG South Transect Snow

• All good here nothing to change.

Teller 47

• Guy wire off again creek side
• Anemometers
  • Lower anemometer at 275 magnetic pointing east to west
  • Upper at 270 magnetic pointing east to west
• Baud rate on md485 set to 9600. I always forget so might need to adjust serial port speed before collecting here
  • Should really buy a couple of the rs232 cables for the cr6 cas sites
• Screwed up program change last fall and recorded extreme high resolution snow depth here. Fixed that. Downloaded data from microSD card.
• Should look at pressure data here and compare to teller bottom.
• There are flies in the vent and it should be replaced
• Three battery setup lasted all winter.
• Not much water in bucket but still dumped.
• I think we have a baby oil in conex for fall 2022 geonor.

Teller 47 Snow

• Vertical pipe bent a bit over the winter.

Teller Top

• Was going to disconnect and reconnect wiring for HMP155 to see if the weak connection is not the sensor.
  • might also try leaving sensor turned on for longer in program (a to do for when CNR4 returns recalibrated)
  • Musk Ox within 50 meters of station prevented a visit.

Snow Stand Improvements

• Shipped out in March parts to add a snow depth side diagonal support (just need to buy the pipe).
  • Teller 47 snow
  • KG-IS5 snow
  • Teller IS2 2x
• Should also add back side guy wires to:
  • Teller IS2 2x
  • Teller 47 snow
  • KG-IS5 Snow 2x
