Abstract. Glacier melt is an important source of water for high Andean rivers in central Chile, especially dry years, when it can be contributor to flows during late summer and autumn. However, few studies have quantified glacier contribution streamflow this region. To address shortcoming, we present analysis meteorological conditions ablation Universidad Glacier, one the largest valley glaciers Andes Chile at head Tinguiririca River, 2009–2010 season. We used measurements from two automatic...
Abstract Despite their importance as freshwater reservoirs for downstream river systems, few glaciers in central Chile have been comprehensively surveyed. This study presents ground-penetrating radar (GPR) and field-based observations characterizing the englacial basal conditions of Glaciar Olivares Alfa (33°11 0 S, 70°13 W), Chilean Andes. Using a 50 MHz mounted onto helicopter platform, data were collected covering large portions glacier accumulation ablation zones. The revealed boundaries...
Known for their important role in locally enhancing surface melt, supraglacial ponds and ice cliffs are common features on debris-covered glaciers. We use high resolution satellite imagery to describe pond-cliff systems velocity Verde glacier, Monte Tronador, Southern Chile. Ponds represent up 0.4 2.7% of the glacier area, respectively. Through analyzed period available data, we found a seasonality number detected ponds, with larger at beginning ablation season less end it. Using feature...
This study examines the distribution and temporal evolution of glacial lakes in Southern Patagonian Icefield (SPI) between 1986 2023. The question addressed is how these respond to climate change, what risks lake outburst floods (GLOFs) may arise. Monitoring crucial due their connection with sudden water release events potential impact on region.   A combination Landsat Sentinel-2 satellite images was used detect analyze 313 2023 inventory. Empirical models were applied estimate...
Abstract. Glacier melt is an important source of water for Andean rivers in central Chile, especially dry years when it can be the main contributor to lowland flows late summer and autumn. However, few studies have quantified glacier contribution river runoff. To address some these shortcomings, we present analysis meteorological conditions Universidad glacier, a large valley Mediterranean climate Andes Chile at head Tinguiririca river, 2009–2010 ablation season. We used measurements from...
We have used seismic refraction surveys of a wave-cut platform from field site in South West England to characterize the impact natural fracture networks on velocities and anisotropy.
