Paleo-Hydrothermal Predecessor to Perennial Spring Activity in Thick Permafrost in the Canadian High Arctic, and Its Relation to Deep Salt Structures: Expedition Fiord, Axel Heiberg Island, Nunavut

<div>Location map of the White Glacier site (star) in Axel Heiberg Island, Queen Elizabeth Islands, Canadian Arctic Archipelago. Icefields are light grey, generally capping 1500–2000 m high mountains (dotted lines). The dashed line outlines the Sverdrup Basin with a thickness of up to 12 km of Paleozoic to Paleogene sedimentary and volcanic rocks, including Carboniferous salt beds at depth and diapiric salt-anhydrite-gypsum structures that reach the surface.</div>
