Methodological proposal for the analysis of the evolution of glaciers since the Little Ice Age and its application in the Tröllaskagi Peninsula (northern Iceland)
In this paper we propose a methodological sequence for the study of glaciers and climate change, and for the use of glaciers as indicators of climatic evolution. Our proposal includes different techniques focused on: mapping glacier extents at different dates, measuring front variations, calculating...

In this paper we propose a methodological sequence for the study of glaciers and climate change, and for the use of glaciers as indicators of climatic evolution. Our proposal includes different techniques focused on: mapping glacier extents at different dates, measuring front variations, calculating areas and volumes, analyzing glacier Equilibrium-Line Altitudes (ELA), statistical treatment of climate series, and the application of glacier-climate models that relate temperature and precipitation and enable paleoclimate reconstruction. This methodology was tested by remote monitoring of three highly sensitive debris-free glaciers in the Tröllaskagi peninsula (northern Iceland) since the end of the Little Ice Age (LIA), and the results show an average retreat of 1.3 km as well as a reduction in area and volume of 25% and 33% as a result of the warming that began at the end of the LIA.
