Model-derived southern elephant seal arrival curves for King Edward Point and St Andrews Bay, South Georgia

This dataset comprises modelled x-y fits to three arrival curves that describe the number of female southern elephant seals (Mirounga leonina) present on the beaches over the breeding season (September - December) at South Georgia. The curves are: (i) a historical multi-year curve derived from the King Edward Point (KEP) long-term count series (1995, 1996, 1998, 2000, 2015-2024), (ii) a curve derived from St Andrews Bay count data for 2024, and (iii) a weighted combined curve generated from the fitted KEP and St Andrews Bay curves. For each curve, the dataset provides date, day-of-year, and fitted proportion of peak abundance across the breeding season, which can be used to correct counts made either side of the breeding peak, to predicted peak haul-out abundance. This dataset forms a component of Darwin Plus 214's efforts to re-census the southern elephant seal (Mirounga leonina) population at South Georgia for the first time in 30 years. These data are intended to enable independent reproduction of the published arrival-curve figures, and reuse of the fitted seasonal correction curves. This project was funded through Biodiversity Challenge Fund Darwin Plus Main stage grant, DPLUS214.
