Cumulative Annual Mass Balance for Gulkana and Wolverine Glaciers

graph of cumulative mass balance for two Alaskan glaciers

Detailed Description

Figure 5. Cumulative annual mass balance for the two Alaska USGS benchmark glaciers, showing the traditional field data (red and blue lines) as adjusted by geodetic mass balance estimates (points with error bars). The bold horizontal line at zero demarks positive versus negative mass changes, with glacier growth and advance indicated when curves pass above this line.
