Hydrogen isotope data from speleothem WB-21-5-A used for the paleotemperature reconstruction

The dataset includes speleothem fluid inlcusion hydrogen isotopes used to reconstruct climate in southeastern Alaska during the past ~3,500 years. Speleothem WB-21-5-A was collected in Wishbone Cave (55.774 N, -133.191 E; 420 m.a.s.l.) on May 21, 2022. The data collection was completed between September 2021-March 2022. Stable/fluid inclusion isotopes were measured on a ThermoFisher Delta V isotope ratio mass spectrometer.
