Exploratory study for the development of technologies required for biological, geological and physical-chemical entry and sampling in subglacial lakes under high contamination-free conditions. The proposed activity is part of an international initiative, promoted and sponsored by SCAR and COMNAP in which Italy is also represented. The scientific objective is the development of miniaturized technologies for the execution of chemical-physical-biological measurements and of remoting technologies for the transport of instrumentation to the operational site, possibly enabling "in situ" sampling and material recovery operations.
