Alkalinity, DIC, δ13C-DIC, major and trace elements, and stable water isotopes data in water samples from a degrading permafrost landscape at subarctic Iskorasfjellet, northern Norway


From September 22nd to October 6th 2020, we collected water samples daily from the outlet of the Gaskabohki catchment, a small subarctic watershed at the mountainside of Iskorasfjellet in northern Norway, to investigate how DIC (dissolved inorganic carbon) and AT (total alkalinity) may change under different environmental forcing (changing precipitation and temperature). We further sampled weekly (3x) at three stations upstream of the outlet to track the changes of the carbonate system with distance from the spring. Besides this temporal examination, we also expanded the investigation spatially, by collecting water samples from seven further catchments, some of which stretch as far as the Barents Sea with different lithologies and varying extent of permafrost. At all sampling sites, we collected water samples for DIC and AT, δ13C-DIC, major and trace elements, and stable water isotopes (δ18O-H2O and δ2H-H2O). We also recorded water temperature, electrical conductivity and turbidity. Finally, at the outlet of the Gaskabohki catchment, we performed a discharge measurement once a day, at the same time as taking the water samples.
