2.1 Population Information
The Black-browed Albatross is a marine species that inhabits Antarctic, subantarctic and temperate waters and occasionally enters the tropics . It can tolerate a broad range of sea-surface temperatures from 0–24º C or probably more based on occasional records from the tropics. It forages around the breaks of continental and island shelves and across nearby underwater banks, but also frequents other marine habitats, such as oceanic waters and the iceberg belt at the limit of the Antarctic pack ice. In the non-breeding season it follows cold water currents north to the continental shelves of Australia, South America and Africa where it can occur in coastal and inshore waters and sometimes enter fjords and channels.[fig3]

5.1 Population monitoring and research
• The population on Macquarie Island has been monitored annually since 1994. The population on Heard Island has been surveyed opportunistically since 1947–1948 . The populations on the McDonald Islands and Bishop and Clerk Islets have been surveyed opportunistically on a few occasions each .In future, it is intended that the populations on Heard Island and the McDonald Island will be surveyed at intervals not exceeding 10 years.
• Satellite tracking of breeding birds has been conducted at Macquarie Island to determine their foraging range at sea .
• Seabird bycatch data have been collected for longline and trawl fisheries operating in Australian waters to determine incidental mortality rates .
• The presence of avian parasites, avian disease and marine pollution is monitored on Macquarie Island .
• Research is being undertaken to develop techniques to survey populations of albatrosses and giant petrels remotely and rapidly .
• A genetic profile of the population on Macquarie Island has been developed .[fig 6]
