Site is a member of the Seward Peninsula Sites Research Area.

June 2008 Trip

• Download Data
• Send new program (snow sensor)
• add net radiometer

Problem Sensors (as of June 2008)

• Met Sensors look good.
• All Soil sensors are broken (animal chew primarily)
• Snow is odd but perhaps okay. 400px

June 14 trip follow up: The snow arm came undone (I'm guessing time-wise early in the winter). So, the data is probably bad until we can figure something else out for this site.

Site Visit 8/27/08:

YSI 44004 model thermistor
Installed new soil temperature string:
0 cm bgs
5 cm bgs
15 cm bgs
25 cm bgs
35 cm bgs
70 cm bgs

Pulled Net Radiometer for fall.  Better secured snow depth sensor

2009 To do

Bring out new wiring for the multiplexer and also precision resistors to put into the broken soil temperature slots. This is follow up to the bogus resistance being measured in the new thermistor string installed August 2008. My away from the site guess is that there's a foul up in the multiplexer wiring rather than a problem with the data logger but would be good to bring a new logger and wiring panel out just in case.
