a Relationships between source water precipitation hydrogen isotope values (δ2H) and oxygen isotopes (δ18O) in samples collected between 1965–2016 CE from the most proximal weather stations in Stanley and Ushuaia along the global (GMWL: black) and local (LMWL: gray) waterlines45. b Monthly temperatures at the nearby (~10 km away) Grytviken weather station (see Fig. 1a)23,42. Regression fits with summary statistics between plotted variables are shown in gray. The pinks star (n = 2) in panel a highlights the isotope value of Lake Diamond water samples taken in February 2015.
