At Thule Air Base on the coast of Baffin Bay (76.51 ∘ N, 68.74 ∘ W), we continuously measured water vapor isotopes ( δ 18 O , δ 2 H ) 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 isoto...
