Snow salinity measurements were obtained doing classical snow pits during the ALERT2018 campaign in May 2018 over the sea ice in the Lincoln Sea. Snow pits were taken at representative locations of the floes. Measurements were done on an undisturbed shaded working wall of the snow pit by extracting snow samples in 3-5 cm resolution to plastic bags. The samples were allowed to melt in a heated tent and salinity was determined using the WTW Conductivity portable meter ProfiLine Cond 3110.
