Oxygen (dO18) and hydrogen (dH) isotope ratio data from sea ice samples taken during MOSAiC leg 4 (PS122/4). Sea ice samples were taken from Jaride and Alli's Ridge. Sea ice cores were extracted f 139 rom the ridges using a 9 cm inner diameter ice corer (Kovacs Enterprise Mark II coring system) powered by a cordless electric drill. Salinity/isotope ice cores were stored in sterile U-Lines bags (sections < 1 m), immediately placed in Styrofoam boxes and transported back to the ship within 2 hours of sampling. Ice cores were stored in a -20°C walk-in freezer until processing. The ice cores were cut into ~5 cm sections using a stainless steel, electric butcher band saw. To ensure we captured potential transition zones within the sea ice (i.e., rapid transitions in salinity), we only cut to the top or bottom of natural breaks in the ice cores (i.e., some sections were thicker or thinner than 5 cm but all in the range of 2-7 cm). The samples were placed in plastic cups with lids and melted at room temperature. ...
