ABSTRACT:

Field point glacier mass balance observations (i.e. snow water equivalent and snow/ice ablation) collected on the Gilkey Glacier, Southeast Alaska, between 2012 and 2015. For snow water equivalent (SWE) observations, density measurements are made using full-snowpack-depth core samples, and depth measurements are to the previous year's summer surface. For melt observations, height changes are recorded using drilled (i.e. fixed in ice/firn) ablation stakes or wires, with ice density assumed at 850 kg/m3.
Columns include:
A-C: Internal database identifiers
D: Name of stake/site
E: Elevation, in meters above sea level
F: Water equivalent balance (positive indicates gain over listed time span, negative indicates loss) in meters water equivalent
G: Error (currently N/A)
H: Season (winter, summer, or annual net balances)
I: Strata (N/A)
J: Start date (initial observation date)
K: End date (final observation date)
L: Source, i.e. who took the measurement
M: Any additional notes
N: Geometry (N/A)
O: Latitude of observation
P: Longitude of observation
