# daypack for working

===Rough on-site todo===
# Copy wiring of Grid Site
# Transfer wires to new multiplexer & Logger
# Snowsurveys
# Measure Heater Resistances for all thermal conductivity probes
# Look to see if the C site pit 2 thermal conductivity sensors could be connected to a lower instrument enclosure.
# configure C as pakbus router for grid
## http://www.campbellsci.com/forum/messages.cfm?threadid=6E4ABAA0-81A1-4158-B850230D8A56A2EF

===Re: Snow Surveys===
''Larry,''<br>
''Attached are the grid corner coordinates (DGPS) of the end-of-winter snow surveys I did in 2012 and that I repeated last week (all but site A). I used the MagnaProbe and have thousands of measurements from each grid. The measurements are aligned in ~S-N transects, which are located 4 m apart with a measurement every ~ft. These measurements overlap geophysics transects (John, Craig, Susan's).''<br>
''Last year's average snow depth was about 51 cm, this year I think it was 39 at site B and C (site D 50 and 37 cm, respectively).
I also took density measurements at each site.''<br>
''I do not think it is realistic to ask anyone to repeat this snowdepth survey every day during the melt. In fact, it would be impossible time wise. Instead, perhaps do a daily survey (of a portion of) the outer lines of the grid, ie its western and southern perimeters, for example?? I think it would be good to follow the "L" protocol of Rovansek. I also think we need a measurement every <0.5m in order to capture the spatial mosaic of snow accumulation in these landscapes.''<br>
''I think it is critical to perform the ablation survey, including snow density, about the same time every day for each site (i.e. site A at 10am, Site B at 11am etc). ''
