Glaciospeleology: hobby, sport, or science?

English version of an earlier lesson by Jerzy Giżejewski.

Glaciospeleology is one of many exploratory activities (consisting of discovering, documentation and research). It is deicated to ice caves - forms, which are similar to karst caves, but formed within glaciers and ice sheets. Glaciospeleology requires ability to work with specialised eqiuipment and experience in walking within caves. At this level it can be seen as a hobby or sport. However, when the techniques of speleology are used to conduct studies of glacier's interior it becomes a specialised branch of glaciology - the science of glaciers.
During the lesson we will see the basic equipment, learn how to use it, show photographs of glacier's interior and results of research.
