Observation of seabirds in the Southern Ocean in 1988/89
Abstract / Description:
This paper examines the numerical and species distribution of birds in the sub-Antarctic area of the Southern Ocean to the south of 60°S. Thirty minute observations were made daily during daylight hours at 8:00; 12:00, 16:00 and 20:00 ship-time, while sailing between Antarctic stations and while en route to ports of call. Maps summarize the distribution of 14 bird species as well as of the individual species: Antarctic, snow, and cape petrels and the southern fulmar. Ice distribution patterns prevailing over the study period are discussed as is the wide variability of numerical and species distribution in each oceanic sector of Antarctica.
