Mean values of the oxygen-isotope ratio relative to standard mean ocean water (δ 18O, in ‰) reported for 46 sites on the Greenland ice sheet are compiled together with data on mean annual surface temperature, latitude, δ 18O elevation, and mean annual shortest distance to the open ocean denoted by the 10% sea-ice concentration boundary. Stepwise regression analyses, with δ 18O as the dependent variable, define two robust models. In the forward mode at the 99.9% confidence level, onlydoi:10.1017/s0260305500014051 fatcat:jokhheic6rdhvklmbep2izqsze
