WebThe mean annual balance for the 1984-2024 period has been -0. 5 m/a. The mean cumulative mass balance loss has been -18 m w.e, which is a minimum of 21 m of glacier thickness lost. North Cascade glacier average thickness ranges from 30-60 m. Thus, 25-40 % of the volume of these glaciers has been lost since 1984. WebGlacier mass balance is measured either by glaciological (stake) or geodetic methods (Cogley, 2009; Zemp et al., 2009, 2015 ). Both annual mass balance rates and … WebAt each of the three benchmark glaciers, changes in mass balance have been summed over time to determine the cumulative change in mass balance since a re ference year. For the sake of comparison, all three glaciers use a reference year of 1965, which is set to zero. Thus, a negative value in a later year means the glacier has lost mass since 1965. fixed width snowflake
