Abstract At Thule Air Base on the coast of Baffin Bay (76.51° N, 68.74° W), we continuously measured water vapor isotopes (δ¹⁸O, δ²H) at a high frequency (1 s⁻¹) from August 2017 through August 2019. Our resulting record, including derived deuterium excess (dxs) values, allows an analysis of isotopi...
