Little Ice Age glacier extension and retreat in Spitsbergen Island (High Arctic, Svalbard Archipelago)
The influence of the Little Ice Age on the glaciers of Spitsbergen has been well documented by many investigations since long time. This paper studies, measures and presents new data on the Little Ice Age maximum glacier extension and retreat by aerial photo interpretation and Geographic Information...

The influence of the Little Ice Age on the glaciers of Spitsbergen has been well documented by many investigations since long time. This paper studies, measures and presents new data on the Little Ice Age maximum glacier extension and retreat by aerial photo interpretation and Geographic Information Systems (GIS) tools use. It also elaborates cartography where all the results are expressed in greater detail. During the LIA maximum the Island of Spitsbergen was covered with a 7.34% more of ice than today. After the Little Ice Age, the total glacier area loss was 13.84%, which means a total of 2769.8 Km2 over the 20,008.7 Km2 of the total glaciated in the current context. The analysis of the maximum Little Ice Age glacier extension in the major drainage basins brings important differences among them; hardly 100 years ago some basin drainage increased the glacier area more than 24% (in the western and central region of Spitsbergen), while others less than 5% (in the northeast region of the Island).
