We aim to reconstruct precipitation and sea surface temperature on decadal to millennial [...] southern hemisphere westerly wind belt (SHW) encircles Antarctica, tracking the mid-latitude meridional sea surface temperature gradient (e.g. Lamy et al., 2010 ). The SHW is an important component of global [...] understanding of the dynamics of the SHW and temperature evolution. To this end, we investigate a north-south transect of marine and lake sediment cores spanning the range of the SHW (Fig. 1). From these
