Ice core water stable isotopes (¹⁸O and D) and salinity in the Canadian Arctic Archipelago in the summer of 2019


This data contains ten (10) geolocated water stable isotopes and salinity measurements from three (3) sea ice cores collected during the cruise. Sea ice core sampling was conducted for three (3) ice coring stations. A sea ice core drill was used to collect the cores. Total length of each core was recorded as well as the temperature per 10 cm interval. The cores were then sectioned per 20 cm and the sections were thawed in different Marvin bottles. Once thawed, multiple water salinity measurements were taken using a YSI professional series digital probe. Water samples were transferred to a 30-mL Nalgene bottles that were filled to the brim. Bottles were tightly closed, sealed with parafilm, and placed inside sampling bags. A total of ten (10) samples were collected from the ice core collected. All water samples were transported to the Atmosphere, Climate, and Ecosystems lab at the University of Illinois at Chicago for processing. The δ¹⁸O and dD were measured using a Picarro l2130-I CRDS water isotope analyzer with a wire mesh inserted in the vaporizer inlet to trap salt from the seawater. Fifteen injections were made for each sample and necessary corrections to address 'memory effect' were employed. Measurements were normalized using the dD and δ¹⁸O values of internal water standards. Header includes following details: event, core segment (cm), latitude, longitude, sampling date, campaign, sampling method, location, isotope analyzer, salinity sensor, ¹⁸O values (‰), D values (‰), salinity values (psu).
