The hydrogen isotopic composition (2H/1H, or d2H) of palmitic acid (PA) was measured in surface sediments from the Laptev and Kara Seas in the Russian Arctic to evaluate its use as a paleohydrographic proxy. d2HPA values in surface sediments varied by 118‰ over a 21 ppt range in mean annual surface...
