Hydrological and glaciological data were gathered in the watershed (1.37 km2) of the Antizana
Glacier 15 (0.7 km2) in the periods 1997–2002 and 1995–2005, respectively. In addition, tracer experiments

Hydrological and glaciological data were gathered in the watershed (1.37 km2) of the Antizana
Glacier 15 (0.7 km2) in the periods 1997–2002 and 1995–2005, respectively. In addition, tracer experiments
were carried out to analyse the flow through permeable morainic deposits located between the glacier snout
and the runoff gauging station. Over 11 years, the mean specific net balance of the glacier was negative
(–627 mm w.e.), despite the occurrence of positive values in the La Niña years (1999–2000). From the
glacier net mass balance between 1997 and 2002, it was found that the mean flow originating from ice melt
was significantly higher than the mean discharge measured at the hydrological station. Analyses of tracer
experiments and of the different components of the hydrological balance suggest groundwater flow that
originates below the glacier accounts for the remaining water. This result is important for regional analyses
of available water resources and for the relationship between hydro-cryospheric processes and volcanic activity.
