That cryokarst is 1. a non-karstic term. land surface with closed depression (usually small and shallow) formed by alternate freezing and thawing of permafrost or ground-ice overlying different rock, including limestone. the term 'cryokarst' is more common in europe while the term 'thermokarst' is used in america [20]. 2. a karst-like periglacial, or formerly periglacial, landscape superimposed upon unconsolidated, superficial deposits. cryokarst is characterized by small depressions or pits that develop due to settlement of overlying deposits into voids formed by the melting of entrapped ice. also known as thermokarst [9]. synonyms: (french.) cryokarst, thermokarst; (german.) thermokarst, cryokarst; (greek.) thermokarst; (italian.) criocarsismo; (russian.) termokarst, criokarst; (spanish.) criokarst, thermokarst; (turkish.) don karsti; (yugoslavian.) toplotni krs, temokarst.?

Eis- und Lufttemperaturmessungen im Schönberg-Höhlensystem (1626/300) und Modellvorstellungen über den Eiszyklus
Abstract:
Currently 34 entrances to the Schönberg- Höhlensystem are known, giving rise to a complex air ventilation pattern. Ice is present in some near-surface parts of the cave and its volume and geometry varies significantly. A significant reduction of ice was observed between 1970 und 2002, and hitherto unknown entrances were released by the melting process. Measurements of ice profiles started in 1994 and the air temperature has been logged since 1995. These data showed that pits of the Raucherkarhöhle extending to high altitude and connections to the Feuertal-Höhlensystem are responsible for the main supply with cold air. The presence of ice is subject to medium- to long-term variations depending on the changing circulation of air between the different cave levels which themselves are forced by the periodic opening and closing of pits by near-surface ice. In stark contrast to the current trend of atmospheric warming in the Alps the cave has been experiencing gradual cooling during the past years. Pits critical for cold air supply are currently open and cold winter air can reach the level of the Kleiner Rundgang, wherethe ice started to grow following an ice-free period. In the Eisstadion, the temperature is currently falling and the ice also began to grow after a long-lasting melting period due to positive year-around. A model is presented in which the apparently cyclic opening and closing of entrances control the complex ventilation pattern and hence the high extent of ice dynamics in this cave between 1965 to 2007.
