Continuous seawater isotopic (δ18O, δD, and d-excess) observations from 2021 Arctic cruise on United States Coast Guard Cutter Healy
The dataset presented here includes isotopic measurements (δ18O, δD, and deuterium excess) of seawater to assess contributions of freshwater and identify different ocean water masses during a 2021 Arctic cruise on board the United States Coast Guard Cutter (USCGC) Healy. The cruise (HLY21TD, HLY2101...
