Future glaciological instrumentation at the South Pole (IceCube Upgrade, RAID and beyond)
- David Besson (University of Kansas)
Seismograms from the South Pole have been important for seismological observations for over six decades by providing (until 2007) the only continuous seismic records from the interior of the Antarctic continent. The station SPA (South Pole, Antarctica) has undergone many updates over the years including being converted to a digitally recording station as part of the Global Seismographic...
IceCube showed that dustloggers deployed in freshwater boreholes provide highly detailed Antarctic histories for mapping chronology across the continent and Southern Ocean. Developed over the same time, the Ice Diver cryobot has proven potential for realizing a deep Philberth probe to explore ice anywhere with a small logistic footprint. The two technologies can be united naturally, and an...
Developed and applied to ice masses over the past decade, borehole optical televiewing (OPTV) is a logging technique that records a geometrically accurate, full-colour (radial) image of the complete borehole wall at a typical resolution of 1 mm. Borehole OPTV has been successfully deployed at temperate and polythermal valley glaciers, at Antarctic ice shelves, and at the Greenland Ice Sheet –...
Ice boreholes have been shown to be stable for several decades, if filled with a non-freezing fluid that has the same density as ice. This enables repeated observations and occupations by instrumented probes, making long time-series measurements possible. We recently learned that Gen-2 is exploring the possibility of such a long-term access hole for calibration purposes.
