This dataset contains the results from surveys of Antarctic Fur Seals (Arctocephalus gazella) on Heard Island during the summer of 1987-1988. As well as habitat descriptions, age, sex, count of adults and pups were determined. The three major aims of the study include: to determine accurately the location of pupping sites; to determine the extent of the pupping season, the median date of birth and the number of pups born; and to census fur seals on as much of the island as possible in order to determine the number of animals ashore and to document changes in numbers during the summer.

This dataset contains Antarctic Pack Ice seal (APIS) observations (both ship and aerial based) collected between 1994 and 2000.

This data also includes some historic data collected between 1985 and 1987. The four species of Antarctic pack ice seals (crabeater, leopard, Weddell, and Ross seals) are thought to comprise up to 50% or more of the world's total biomass of seals. As long-lived, top level predators in Southern Ocean ecosystems, pack ice seals are scientifically interesting because they can assist in monitoring shifts in ecosystem structure and function, especially changes that occur in sensitive polar areas in response to global climate changes.

ARGOS Tracking devices called PTTs are attached to several species of birds, seals and whales. Locations include Heard and Macquarie islands, Auster and Taylor rookery, Berchervaise island and islands in the Antarctic peninsula.

A catalogue of electron microscopy images mostly of biological origin and used in identifying new species of marine and terrestrial organisms. These organisms are extremely important in the Antarctic food web and many of them have microscopic characteristics which show how successfully they have adapted to their extreme environment.

At Heard Island, Southern Indian Ocean, seals were branded between 1949-1953. Seal length was measured in feet and inches. Recaptures of seals were made up until 1955, and growth and age-specific survival was calculated.

At Macquarie Island 1000 seals were weighed per annum between 1993-2003 at birth and individually marked with two plastic flipper tags in the inter-digital webbing of their hind flippers. These tagged seals were weighed again at weaning, when length, girth, fat depth, and flipper measurements were made. Three weeks after weaning 2000 seals were permanently and individually marked by hot-iron branding. Recaptures and re-weigings of these known aged individuals were used to calculate growth and age-specific survival of the seals. Similar data were collected from elephant seals between 1950 and 1965 when seals were individually marked by hot-iron branding. Mark-recapture data from these cohorts were used to assess the demography of the declining population. Length and mass data were also collected for these cohorts and were used, for the first time, to assess the growth of individual seals without killing them.

During the 5-1/2 months on the island most of the beaches were surveyed regularly for seals (3 species) and fishing debris. Leopard Sea surveys were made daily in the first three months for the Four Bays. In the last three months they were continued on a daily basis for Atlas Cove and Corinthlan Bay and once every three days for South West Bay.

Seabird observations from ships either performing marine science work or taking personnel and cargo to various Antarctic stations. Incidental observations of whales and seals are also noted. This set also contains data from the BIOMASS cruises in the 1980's.

This collection of sightings represent the first evidence of sub-Antarctic Fur seals Arctocephalus tropicalis visiting Heard Island. They normally breed on the Prince Edward Islands and Iles Crozet.
