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.

Circum-Arctic Structural Events: Tectonic Evolution of the Arctic Margins and Trans-Arctic Links with Adjacent Orogens
The circum-Arctic region has received considerable attention over the past several decades with vigorous debate focused on topics such as mechanisms for opening the Eurasian and Amerasian basins, the importance of plume-related magmatism in the development of the Arctic Ocean, and mechanisms for ancient terrane translation along the Arctic margins. In recognition of the 25th anniversary of the Circum-Arctic Structural Events (CASE) program, an international polar research effort organized and led by the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) of Germany, this volume presents results from 18 major field expeditions involving over 100 international geoscientists from a broad spectrum of disciplines. The resulting publication focuses on the Proterozoic to Cenozoic tectonic evolution of the circum-Arctic region with correlations to adjacent orogens.
