Southwestern South Atlantic Risso's dolphins (Grampus griseus) bone collagen isotope composition. δ13C and δ15N values and C/N ratios of each Grampus individual analyzed. Location of stranding: Bahía San Sebastián (BSS; 53°10'S, 68°30'W), Estancia Cullen (Cullen, 52°52'S, 68°27'W), Los Chorrillos (52°21'S, 68°13'W), Punta María (53°57'S, 67°27'W). Maturity classes were determined using two methods. First, by epiphyseal fusion: 1 = no fusion; 2 = subadult, partly fused; 3 = adult, all epiphyses fused. Second, by total body length (TBL): M = sexually mature individuals (>270 cm total length), I = sexually immature individuals (<270 cm total length). ND = not determined. Determination of sex: M, F = from intact animal; (M), (F) = from pelvic bones, ND = not determined. All specimens (RNP Goodall collection) are archived in the Museo Acatushún de Aves y Mamíferos Marinos Australes, Estancia Harberton, Tierra del Fuego, Argentina. We separated the individuals into two groups (GG1 and GG2) as suggested by Riccialdelli et al. (2010).
