Snow Depth Measurements:

The data file (SNO-M94) contains snow depth measurements (cm) made 
on 8 May 1994 at the ARCSS site at Barrow, Alaska.  Measurements 
were taken on the 1-km grid established by project directors, as 
described in their referenced works.  A grid spacing of 100 m was 
previously surveyed and marked with wooden stakes, visible above 
the snow pack.  Thus, an array of 11 x 11 was established, 
yielding 121 data points.  Snow pack depth was measured by probing 
at the stakes.  This was done by Yuri Shur and Ken Hinkel prior to 
meltout.

The data are reported in space-delimited ASCII format.  The 121 
rows represent the sampling points, numbered as indicated on the 
ARCSS site map.  The first column contains the point number, 
beginning with point 1 in the north west corner of the grid.  The 
second and third columns contain the UTM coordinates of the 
surveyed stakes, and represent the northing and easting, 
respectively.  The forth column contains the snowpack thickness in 
cm.  The mean depth was 61 cm, with a standard deviation of 35 cm.

Soil temperature data were collected at the same site and date, and 
are included in the Soil Temperatures for Happy Valley and Barrow,
