Measuring instruments of the Swiss Arctic researcher Alfred de Quervain are among the historical treasures of GIUZ. They were featured in the "Sternstunde Philosophie" on Swiss television.
Alfred de Quervain took the theodolite and the sextant with him on his expeditions to Greenland in 1909 and 1912. Thanks to his measurements, there are 100-year-old data on the tongue of the Eqip glacier at the edge of the Greenland ice sheet. These make long-term comparisons and insights into the dynamics of the glaciers possible. For this reason, the Eqip glacier has become an important research object of the Glaciology and Geomorphodynamics unit at GIUZ.
