Re: Snow Surveys

Larry,
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).
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.
 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.
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).
