Company HYDEKO-KV Bratislava received licence for drilling and sampling project in the Dobsina Ice Cave from the Ministry of Environment of the Slovak Republic, Decision No. 5213/967/01-5.1 from 25 January 2002. The Initiation and international background of the project was covered by the company SELOREEIG, Amsterdam, The Netherlands as a result of preparation of project proposal for EU funds competition. Technical aspects (drilling, sampling, and isotopic and chemical analyses) were solved mainly in co-operation with University of Copenhagen, Denmark.
So far no special measurements of the ice age were accomplished in the cave, so no representative data on ice age was currently available on the ice. The goal of this project was to analyse climate and environmental changes by detailed study of continental cave ice using isotopic methods and methods of chemical analysis. According to existing knowledge, it could be reasonably supposed that cores of cave ice from Dobsina could add new information to the Holocene climate record of continental Europe.
The contribution presents details about projecting, sampling, drilling, samples storing and transport of Dobsina Ice Cave samples, special technical conditions regarding drilling in so called "warm ice", and manipulation with samples before isotopic and chemical analyses. Interpretation of the results is presented in this workshop in the contribution by H.B. Clausen, et al. "Continental ice body in Dobsina Ice Cave (Slovakia) - Part II. - results of chemical and isotopic study".
