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

Table 2

Summary data of the major geochemical parameters of waters collected from spring outflows (Gypsum Hill Springs, Colour Peak Springs, and Wolf Springs) and associated hydrologic measurements. Given that numerous spring outlets exist at Expedition Diapir and Colour Peak Diapir, geochemical data shown here represent the average of previously reported results. Concentrations of cations and anions are expressed in mol/kg. at Expedition Diapir and Colour Peak represent the sum of all outlets, whereas only one outlet exists at Wolf Diapir. N.D. = not determined. Data collected since 1997 (C.R. Omelon, MSc thesis); Pollard et al. [3]; Omelon et al. [55, 56]; Perrault et al. [64]; Niederberger et al. [63], Lay et al. [60]; Battler et al. [57].
