Sublimation and melt disturb the environmental information obtained from ice core records in the Andes. In two case studies we demonstrate to what extent these post-depositional processes may remove major parts of the accumulated snow cover. Dark ash layers from the Tungurahua eruption changed the albedo of surface snow on Chimborazo glacier (6268 m, 1°30′ S,78°36′ W, Ecuador) between two ice core drilling campaigns and forced substantial melt. Re-distribution and washout of the chemical… Expand

Equilibrium line altitudes along the Andes during the Last millennium: Paleoclimatic implications
Deciphering the climate changes that influenced the glacial fluctuations of the last millennium requires documenting the spatial and temporal patterns of these glacial events. Here, we estimate the… Expand
Rapid decline of snow and ice in the tropical Andes – Impacts, uncertainties and challenges ahead
Abstract Glaciers in the tropical Andes have been retreating for the past several decades, leading to a temporary increase in dry season water supply downstream. Projected future glacier shrinkage,… Expand
Some preliminary results from the Coropuna (Peru) ice core
Ice core studies have been implemented in tropical region over the last 30 years to study the past climatic variability. A 42m-long ice core from the saddle of the Coropuna glacier (Peru) is… Expand
Elevated stream trace and minor element concentrations in the foreland of receding tropical glaciers
Globally, the ongoing retreat of mountain glaciers will ultimately diminish fresh water supplies. This has already begun in watersheds with greatly reduced glacial coverage. Still unknown are the… Expand
Across the Arid Diagonal: deglaciation of the western Andean Cordillera in southwest Bolivia and northern Chile
Here we review published cosmogenic records of glaciation and deglaciation from the western cordillera of the arid subtropical Andes of northern Chile and southwest Bolivia. Specifically, we examine… Expand
Annual anomalies and trends for TOMS reflectivities (1978–2005) in the Southern Hemisphere
ABSTRACT Annual anomalies of Lambertian equivalent reflectivity (LER) retrieved from the total ozone mapping spectrometer spanning the period November 1978–November 2005 were studied in the Southern… Expand
Major atmospheric particulate matter sources for glaciers in Coquimbo Region, Chile
TLDR
These findings can likely be extended to the nearest glaciers in Northern Chile, which have similar potential contaminant sources from cities, ports, and thriving mining activity, but may not be suitable for southern Chilean glaciers, which are closer to bigger cities and to smoke from residential heating prevalent in winter months and wildfires during the summer.

Secondary Lahars Triggered by Periglacial Melting at Chimborazo Volcano, Ecuador
Periglacial melting processes can provide the water source for secondary lahars triggered by volcanic and/or meteorological phenomena on volcanoes. Between December 2015 and April 2016, four major… Expand
Isotopic time-series partitioning of streamflow components in wetland-dominated catchments, lower Liard River basin, Northwest Territories, Canada
The distribution of stable water isotopes provides valuable insight into runoff generation processes in subarctic wetland regions of the Mackenzie River basin, a major freshwater contributor to the… Expand
Automatic monitoring of weather and climate in mountain areas. The case of Peñalara Meteorological Network (RMPNP)
Abstract. Mountains have a very peculiar climate, are an essential factor in the climate system and are excellent areas for monitoring weather and climate. Nevertheless there is still a lack of long… Expand
