Résumé

This paper presents spatial modelling based abundance and density estimates of pack-ice seals, crabeater, Weddell and leopard seals, based on aerial survey line transect data collected in January 1999 under the Antarctic Pack-Ice Seal (APIS) programme. Estimates are reported for the Antarctic Peninsula and the western Weddell Sea region (90º to 30º W and 60º to 80º S).
