Permafrost & boreholes. Activities 2012

In 2012, the investigations on permafrost and ice boreholes were mainly focused on the retrieving of the instrumental data and the maintenance of the instrumentation. These activities were coordinated by the University of Pavia (Department of Earth and Environmental Sciences) and the Office for Geology and Building Materials Testing of the Autonomous Province of Bolzano with the cooperation of the Ohio State University (Byrd Polar Research Center), the University of Padova (Department of Land, Environment, Agriculture and Forestry and Department of Geosciences), the Hydrographic Office of the Autonomous Province of Bolzano and the University of Venezia (Department of Environmental Sciences, Informatics and Statistics).

Permafrost

 

Permafrost is one of the main components of the Earth’s cryosphere, which is a word indicating all the ice existing on Earth. It is defined as “any subsurface material which remains at or below a temperature of 0°C for at least two consecutive years” and mainly occurs in high-latitude areas of the northern hemisphere (look at its distribution map here).

Permafrost may also exist at high altitude areas of the mid- and low-latitudes, such as the Alps
