4 Observations of pinnipeds were few. Three observations of single Northern Fur Seals (Callorhinus ursinus) were recorded. These records are of interest because Scheffer (1958) reported this species in the winter and spring to range as far south as waters off San Diego, California (32°40' S). Our observations are somewhat to the south (32°15'). Two Steller Sea lions (Eumetopias jubata) were recorded floating together on their backs, exhibiting resting behavior very similar to that of Callorhinus. This species has previously been observed only as far south as San Nicholas Island (33°+). Two observations of single California Sea lions (Zacophus californiacus) were made without comment in the northern non-Grid area.
