This volume is dedicated to Dr. Franz Tessensohn (1939–2019), who initially established terrestrial geoscientific polar research at the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR). In 1979–1980, Franz initiated an Antarctic geoscience research program in the Ross Sea area, which was titled “German Antarctic North Victoria Land Expedition” (GANOVEX), where he also aided in the construction of the BGR’s Gondwana Station in 1983. When the BGR extended its polar research to the Arctic, Franz organized the geoscientific program “Circum-Arctic Structural Events” (CASE) and led the first CASE expeditions to Svalbard (CASE 1), North Greenland (CASE 2), and Ellesmere Island (CASE 4, 5, and 6) between 1992 and 2000, and a ship-based expedition to Nares Strait in 2001. Without Franz’s guidance, organization, and scientific curiosity, the CASE program and Geological Society of America Special Paper 541 would not exist.
