  abstract = {{T}he longest continuous glaciological mass-balance time-series in the intertropical zone of {S}outh {A}merica goes back to 1991 on {G}laciar {Z}ongo, {B}olivia. {P}hotogrammetric and hydrological data have been used to (1) check the specific net balance over long periods and (2) extend the mass-balance time series over the last 50 years. {T}hese data reveal a bias in the glaciological mass balance which can be explained by the field-measurement sampling network. {O}ur study shows a large temporal variability of the surface mass balances in the ablation area and reveals strong relationships between independent surface mass-balance data coming from selected ablation areas with numerous data. {I}t demonstrates the very large contribution (80%) of low-elevation ranges (one-third of the surface) to the specific mass balance and, consequently, the importance of the reduction of the area of the tongue. {W}ith these new results, {G}laciar {Z}ongo offers the longest and most accurate mass-balance series in any {A}ndean country. {T}he dataset shows that {G}laciar {Z}ongo experienced a relatively steady state over the period 1956-75, with even a slight mass gain over 1963-75, and a rapid and continuous decrease since then.},
