ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) (ISMOGLAC) Sampling and in-situ measurements on snow and water, performed into both Kongsfjorden and glacial streams that originate in supraglacial, englacial and subglacial zones of different glaciers (Midtre Lovenbreen, Austre broggerbreen, Vestre Broggerbreen, Kongsvegen). Dataset concerns water isotopes signature of snow and Kongsfjorden water and physical-chemical data of the latter.

Arctic Present Climate Change and Past Extreme Events (ARCA) CD4 core was micromilled at 200 μm increments using a micro-milling method (Drysdale et al., 2012). The stable isotope composition of the powders was measured on CO2 gas released by reaction with 105% H3PO4 at 70°C, which was measured using a mass spectrometer. Isotopic results are reported using the conventional δ-notation in per mille (‰), with reference to the Vienna Pee Dee Belemnite (V -PDB) standard. Instrument : MC-ICPMS, Nu-Instruments Plasma, Finnigan GasBench Parameter : Th**230/U**238 and U**234/U**238 activity ratios, (δ**13)C and (δ**18)O
