Cumulative Mass Balance (m w.e.) Change at the USGS Benchmark Glaciers

Figure 2: The cumulative mass change at each glacier, expressed in meters of water equivalent. Note that each glacier is measured relative to the start of mass balance measurements at that site. Geodetic mass balances (black squares) from photogrammetrically derived digital elevation models are used to constrain the time series (adapted from Fig.4 in O’Neel et al., 2019).
