An extraction probe has been developed which allows vacuum melting of several tons of ice in boreholes down to a depth of 400 m. It mainly consists of an electrical heater and a rubber packer to isolate the section of the borehole in which the extraction takes place. During melting the evolving gases are pumped and collected continuously. The meltwater can be circulated through ion exchange resins or a filter, for collection of dissolved and particulate matter. From the gas samples CO2 is extracted for 14C-dating, Ar for 39Ar-dating. From the meltwater the 32Si activity is measured. Pollen and cosmic dust studies can be performed on filter samples.
