Spatial variability of δ18O and δ2H in North Pacific and Arctic Oceans surface seawater
This study presents new observations of stable isotopic composition (δ18O, δ2H and deuterium excess) in surface waters of the North Pacific and Arctic Oceans that were collected during the sixth Chinese National Arctic Research Expedition (CHINARE) from mid-summer to early autumn 2014. Seawater δ18O...
