Seabird abundance, biomass and prey consumption within Prydz Bay, Antarctica, 1980/1981–1992/1993:
Annual observations of seabirds within Prydz Bay, East Antarctica, between the 1980/1981 and 1992/1993 seasons revealed siginificant changes in abundance of the 9 resident and 15 non-resident species. An estimated 4.85 million individual residents and 2.35 million individual non-residents were prese...
