Salinity profiles of snow on sea ice and sea ice in the Arctic Ocean during winter 2015

Salinity profiles of sea ice and snow on sea ice were measured in the Arctic Ocean during the Norwegian Young Sea Ice cruise in 2015 ( https://www.npolar.no/en/projects/n-ice2015/), an international sea ice drift expedition led by the Norwegian Polar Institute. Salinity is a key parameter for a range of processes related to biology, photochemistry and physics of sea ice, snow on sea ice as well as atmospheric aerosol. Sea ice cores and snow samples were collected during the sea ice drift expedition from the ice floe and transferred to the ship''s laboratory. The aqueous conductivity of melted sea ice core and snow samples was measured and converted into practical salinity units.

Statement: Data set 1 (see also Frey et al., 2019): measurement range of 0-200 mS cm-1 and a maximum resolution of 0.1 &#956;S cm-1 at low conductivities (0-199.9 &#956;S cm-1). The conductivity meter used has an automatic non-linear temperature compensation based on a NaCl solution and reference temperature of 25 degC and was calibrated with a standard salt solution (12.880 mS cm-1 at 25.1 degC), certified and traceable to NIST (REAGECON Prod. No. CSKC12880, Lot No. CS1288012K1). Conductivity values were converted into practical salinity Sp as described in Frey et al. (2019). Accuracy as stated by the manufacturer is ±0.001 psu at low salinities (<1 psu).

Data set 2 (see also Nomura et al., 2018): For calibration of salinity measurement, a Guildline PORTASAL salinometer model 8410A, standardized by International Association for the Physical Sci- ences of the Oceans (IAPSO) standard seawater (Ocean Scientific International Ltd, UK), was used. The accuracy of this sensor was ±0.003.
