distribution and abundance
Abstract
A total number of 182,810 seabirds of 50 species was recorded at Antarctica and South Atlantic Ocean in consecutive summers from 1987 to 1995. 9.281 ten minute censuses were made onboard ships following S.C.A.R. methodology. Six Antarctic and Subantarctic sub-areas were considered for study. The largest abundance was recorded at South Orkney Is. and South Shetland Is. Abundance were compared with all sub-areas and with some environmental factors such as air temperature and ice-cover. The influence between those environmental factors and species distribution is discussed.
