The means and standard deviations of (a) δ13C and (b) δ15N values estimated for seven water zones and fronts: Antarctic zone (AZ), Antarctic polar front (APF), polar frontal zone (PFZ), sub-Antarctic front (SAF), sub-Antarctic zone (SAZ), sub-tropical front (STF) and sub-tropical zone (STZ) from the species-specific isoscapes presented in Fig. 2: wandering (WA), grey-headed (GHA) and sooty (SA) albatrosses, northern (NGP) and southern (SGP) giant petrels
