Precipitation stable isotopes (¹⁸O and D) and salinity in the Canadian Arctic Archipelago in the summer of 2019 ...

This data contains one (1) geolocated water stable isotope measurement from one (1) rain event on 29 July 2019. Shipboard rain samples were collected in a separatory funnel filled with a layer of mineral oil to prevent evaporation. Water samples were transferred to a 30-mL Nalgene bottles that were...

Description
Summary:This data contains one (1) geolocated water stable isotope measurement from one (1) rain event on 29 July 2019. Shipboard rain samples were collected in a separatory funnel filled with a layer of mineral oil to prevent evaporation. 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. It was then 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. 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 event, latitude, longitude, sampling date, campaign, sampling method, location, isotope analyzer, ¹⁸O values (‰) and D values (‰). ...
