a Time series of oxygen isotopes measurements from this study and Wanamaker, et al.15 compared to those calculated from temperature and salinity output from the fully forced CESM-LME simulations, averaged over the Gulf of Maine region at 35 m depth (see the Methods section in the main text for details). The dashed rectangle represents the time period of the graph shown in (b) for ease of comparison. Note both y axes are inverted. b As in (a) but for the shorter period of 1685–2013. The legend shown in (a) applies to both (a) and (b). All oxygen data are normalized (z-scores) so that they can be plotted on the same scale.
