An aerial survey estimate of 1989 grey seal (Halichoerus grypus) pup production in St. George's Bay, Nova Scotia / by M.O. Hammill and R.A. Myers and G. Stenson. : Fs70-8/92-90E-PDF

"Grey seal pup production in the St. George's Bay, Nova Scotia was estimated for 1989 season using aerial surveys. Surveys were flown 23, 30 January and 2 February 1989 resulting in pup production estimates of 4,208 (±1,515), 3,038(±2,365) and 2,219 (±1,609) respectively. The decline in pup production estimates with succeeding surveys covering a larger area, albeit of lower survey fraction indicates that pups were likely missed due to the low survey intensity or emigration of animals from the study area. An aerial survey estimate for pup production obtained by combining transects from the high intensity survey of northern half of St. George's Bay flown 23 January, with the lower intensity survey of the southern half of St. George's Bay flown 30 January results in a pup production estimate of 6,607 (±2,657)"--Abstract, page 2.
