Replicate O-17-excess by continuous flow laser spectroscopy for an ice core section at Summit, Greenland Data DOI: https://doi.org/10.15784/601659 Cite as Davidge, L.

AMD - DIF Record(s) USAP-2019719_1 Abstract This data set contains replicate measurements of D17O from a 92-m deep section of core at Summit, Greenland and other operational data necessary to reconstruct figures presented in Davidge et al., 2022. Details of the entire dataset and a description of the relevant methods can be found in Davidge et al., 2022. The names of each sheet indicate the corresponding figure numbers. The D17O record spans about two years of accumulation. Discrete measurements by laser spectroscopy are provided at 1.4-cm resolution. For the purpose of method development, continuous-flow measurements are provided with nine replicates and are averaged to multiple depth resolutions as described in Davidge et al., 2022.
