2017 NGEE Nome October trip
Revision as of 09:37, 28 September 2017 by 137.229.29.107 (talk)
- Car Rental Reservation: R41747
- 9/29 - 10/6
- Nugget reservation 1346
Activities:
- Nome
- find new base station location with Chad
- return GCI cable modem from Boxer Apartments
- teller
- move snow poles to TLA line
- put one snow pole in each actual snow course center of X for the IS crosses.
- remove remaining poles
- teller bottom:
- check soil moisture #5 (bottom) seems to be not powered / connected.
- teller top:
- double-check data
- thermal conductivity probes working?
- maybe replace cnr4
- and or drill out stripped screws
- replace memory card in camera
- teller bottom
- replace memory card in camera
- sr50a transducer replacement, 2x
- remove 1 PT
- discharge measurement
- Kougarok m64
- bring guy wire markers for K64 met station (at uaf storage)
- setup snow grid for spring (surveying)
- 9/25 waiting on geopdf & shape files from Lauren for this.
- survey the remaining intensive sites out there:
- IS5, IS6, IS8
- soil pit.............
- altar shield
- need 2 2x4 chunks for base
- need 2 more pieces of functional altar shield
- need wood screws to screw vertical pipes to base.
- Original Kougarok:
- download data by radio
- Council
- fix program at C1 Grid
- download C2 blueberry data over radio
- push snow off eddy system.
Sensor Issues
Data Notes
- Double-check thermistor equations
- double-check precision resistor values.
- think about bringing car adapter plus aligator clips etc out so we can tie into station batteries during program compilation.
Teller Bottom Soil:
- teller bottom: confirm that thermistor values as-built match resistor in field.
- Soil Moisture #5... is it connected?
- Heat Flux Plates are doing the wrong thing... are they measured right?
- thermal conductivity thermistors... it kind of looks like the measurement is still settling. The measurement is quite spikey from time to time.
- Looks like VATP3 shifted on 4/21.
- same for VATP4
- same for VATP 6
- same for vatp 8
- same for vatp 9
- can see water pulse around 4/21 in the lower thermistors.
Teller Bottom Spectral:
- Decagon Sensors look good
Teller Bottom Radiation:
- Looks good just need to correct albedo for nighttime.
Teller Bottom Snow Temp Profile:
- Looks pretty good
Teller Bottom Thermal Conductivity:
- data is spikey, in soil pit temperatures
Teller Top Met
- HMP155 is still broken.
- All other sensors look good.
Teller Top Soil:
- I'm suspicious that the precision resistor values for teller top aren't correct.
- vatp4 freezing point is at 2 deg C
- I think there was quite a bit of water running down the probe during snowmelt.
Teller Top Thermal Conductivity:
- something funky going on here, too, as in precision resistor may be off and also the data is quite spikey.
Kougarok Mile 64 Met
- skin temperature looks like there is a loose wire
- Other sensors look good.
Kougarok Mile 64 Spectral
- all sensors look good
Kougarok Mile 64 Soil
Loose Itinerary
- 9/29 (8:18 - 9:36 Twilight to twilight)
- evening: arrive & stay in apartments
- 9/30 (8:21 - 9:19)
- take some storage stuff to dump
- evening: Lily arrives
- stay in hotel
- 10/1 (8:24 - 9:16)
- Teller
- walk the end point of the lines set up in March 2017 and remove the orange poles
- place 4 poles at bottom to help outline location of channel for PTs
- 10/2 (8:27 - 9:12)
- Teller Top:
- change desiccant which will require:
- drill
- drill bit
- tap & die
- replacement machine screws for stripped out ones.
- change desiccant which will require:
- Teller button up for winter, snow pole remainder
- remove one PT at the bottom site
- Teller Top:
- 10/3 (8:30 - 9:09)
- drive to kougarok. download data over radios from K sites
- stretch goal... visit k2 if time for thaw depth measurements
- 10/4 (8:33 - 9:05)
- kougarok m64 winter button up
- ??? soil pit ???
- kougarok m64 finish surveying & deploy snow poles
- 10/5 (8:36 - 9:02)
- Council
- survey 2017 plots?
- download data over radio for C2 (at minimum)
- visit C2?
- fix program at C1
- 10/6 depart
