Application and validation of long-range terrestrial laser scanning to monitor the mass balance of very small glaciers in the Swiss Alps

Fischer, Mauro ; Huss, Matthias ; Kummert, Mario ; Hoelzle, Martin

In: The Cryosphere, 2016, vol. 10, no. 3, p. 1279–1295

Due to the relative lack of empirical field data, the response of very small glaciers (here defined as being smaller than 0.5 km²) to current atmospheric warming is not fully understood yet. Investigating their mass balance, e.g. using the direct glaciological method, is a prerequisite to fill this knowledge gap. Terrestrial laser scanning (TLS) techniques operating in the near infrared...

Sensitivity of very small glaciers in the Swiss Alps to future climate change

Huss, Matthias ; Fischer, Mauro

In: Cryospheric Sciences, 2016, p. 34

Very small glaciers (<0.5 km2) account for more than 80% of the total number of glaciers in mid- to low-latitude mountain ranges. Although their total area and volume is small compared to larger glaciers, they are a relevant component of the cryosphere, contributing to landscape formation, local hydrology, and sea-level rise. Worldwide glacier monitoring mostly focuses on medium-sized to large...

Surface elevation and mass changes of all Swiss glaciers 1980–2010

Fischer, Mauro ; Huss, Matthias ; Hoelzle, Martin

In: The Cryosphere, 2015, vol. 9, no. 2, p. 525–540

Since the mid-1980s, glaciers in the European Alps have shown widespread and accelerating mass losses. This article presents glacier-specific changes in surface elevation, volume and mass balance for all glaciers in the Swiss Alps from 1980 to 2010. Together with glacier outlines from the 1973 inventory, the DHM25 Level 1 digital elevation models (DEMs) for which the source data over...

The New swiss glacier inventory SGI2010: relevance of Using high-resolution source data in areas dominated by very small glaciers

Fischer, Mauro ; Huss, Matthias ; Barboux, Chloé ; Hoelzle, Martin

In: Arctic, Antarctic, and Alpine Research, 2014, vol. 46, no. 4, p. 933–945

In view of the rapid and accelerating glacier retreat observed in the European Alps during the last decades, the repeated creation of glacier inventories is important to understand the spatio-temporal variability of glacier changes and to support modeling studies. This article presents the latest glacier inventory for the entire Swiss Alps (SGI2010) derived by manual digitization from...

Combining glaciological and archaeological methods for gauging glacial archaeological potential

Rogers, Stephanie R. ; Fischer, Mauro ; Huss, Matthias

In: Journal of Archaeological Science, 2014, vol. 52, p. 410–420

Recent climate changes have led to an increase in the exposure of archaeological remains in frozen environments due to the melting of glaciers and ice patches, and the thawing of permafrost. In some cases, the discovery of glacial archaeological findings has occurred due to chance. In order to avoid the risk of losing exceptional, often organic, cultural remains due to decomposition, systematic...
