Description:
Abstract:
Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Additional measurements have been made on Lemon Creek and Taku glaciers, AK to compliment data collected by the Juneau Icefield Research Program (JIRP; Pelto et al., 2013). Direct field measurements of point glaciological data are combined with weather and geodetic data to derive glacier-wide seasonal and annual surface mass balance solutions of each glacier in conventional and reference surface formats (Cogley et al., 2011). Additional details on the calculation of glacier-wide surface mass balance are described in Van Beusekom et al. (2010).
Mass balance is calculated at both a seasonal and annual time-step at each glacier in both a conventional and reference surface format (Cogley et al., 2011). The analysis framework (Van Beusekom et al., 2010; O’Neel et al., 2014) is identical at each glacier to enable cross-comparison between output time series. Vocabulary used follows Cogley et al. (2011) Glossary of glacier mass balance. Mass balance is calculated from direct field measurements of surface mass balance in combination with weather data and imagery analyses.
Purpose:
This collection of data is used to quantitatively record changes in mass at specified glaciers over the period of record. Although these data were primarily collected for the purpose of mass balance, there are many other potential uses, including ecological assessments, remote sensing validation, or water resource applications. Data are included as available, though the history of the project. Additional older, analog records may be available via digitized scans of field notebooks.
Supplemental_Information:
This collection of data is composed of the varied datasets used by the USGS Benchmark Glacier program to measure seasonal and annual mass balance. Products within the release range from raw field data to processed glacier-wide mass balance measurements.

Horizontal_Positional_Accuracy_Report:
Positions are reported to 1 m and the location of the site is known to higher accuracy. However, ablation stakes located on the glacier are moving, and the coordinates represent an average location that the measurement stake flows through on an annual basis. Snow pits and probed snow depths are located close to, but not precisely at site coordinates.
