This dataset contains: 1) GPS tracking data of breeding birds tracked over the 2017/18 season; 2) Prey remains surveyed at the nests of breeding birds during the 2017/18 season The dataset download contains an Excel spreadsheet with several worksheets. One worksheet contains descriptions of each of the column headings of the other worksheets.

These are "found" datasets of general data collection from the KACTAS voyage of the Aurora Australis in the 2000-2001 season. The datasets were compiled by Toby Jarvis as part of his hydroacoustic work, but are not hydroacoustic in nature. The data include voyage reports, relevant GIS data, at sea observations, some drifting buoy data, satellite data, trawls data, underway data, etc. These datasets should be treated with caution, as the quality of the datasets is unknown. The KACTAS voyage was a marine science voyage that visited Mawson, Casey and Davis prior to returning to Hobart.

This is a dataset of biological data collected via observations, trawls, and PTT tags. These data were recovered in 2022 while tidying up various voyage datasets. Original information about the data is unknown, however there are a number of details held within the data. The data were collected on a voyage of the Aurora Australis to the Heard Island area as part of the HIMI Ecosystem Project. The HIMI Ecosystem Project was aimed at examining key predators based on Heard Island, including albatross, penguins and seals, and their interactions with prey, the ocean and benthic environment and commercial fisheries. Work included examining the diet of the animals, tracking them to determine where they feed, and examining prey available in the feeding areas. Scientists from a variety of backgrounds including bird and mammal biologists, marine biologists, oceanographers and marine geologists were involved. The voyage was colloquially known as "HIPPIES". The download file contains three top level folders, "Observation", "PTT" and "Trawl". Data formats include shapefiles, csv files and text files. Described species are: Penguins (King and Macaroni) Albatrosses (Black browed and Sooty) Fur Seals Zooplankton Krill Fish And more...

This metadata record is a parent for all data on Antarctic blue whales collected during the 2015 New Zealand-Australia Antarctic Ecosystems Voyage. Description of specific data sets can be found in the Voyage Science Plan and within child datasets.

Flying bird breeding colonies on Macquarie Island. This is a polygon dataset stored in the Geographical Information System (GIS). Attributes include the species name and the time of the year during which breeding occurs. The species include Black-browed Albatross, Grey-headed albatross, Southern Giant-Petrel and Wandering Albatross.

This is a scanned copy of the vertebrate ecologists report from Macquarie Island, 1985, written by Mark Hindell. The report includes: The diet of the four penguin species breeding on Macquarie Island (Royal, Rockhopper, King and Gentoo). Aspects of the morphology of the four penguin species The past and present status of the southern elephant seal on Macquarie and Heard Islands

This is a scanned copy of the annual report on vertebrate biology at Macquarie Island, 1990, by Rupert Woods. The scanned report contains information on: Elephant seal census Elephant seal tagging program (1984-1985, 1987-1991) Freeze branding Weaner weights Anaesthetics Gastric lavage Opthalmology problems Penguin crush (mass deaths of King Penguins) PTTs and TDTRs Toxoplasmosis Morbilivirus DNA samples (elephant seals and fur seals) Anaesthesia and surgery of birds Details of a neo-natal longfinned pilot whale washed ashore Fur seals (census, euthanasia, injuries, net entanglements) Letters Abandoned elephant seal pup Drift cards Killer whale attack

The populations of fur seals on Australia's two subantarctic islands were exterminated by uncontrolled sealing in the 19th century. Only in the latter half of the 20th century have populations commenced recovering. This project provides key information on the status and trends of recovering fur seal populations in the Southern Ocean, including information on the distribution of foraging effort, food and energy requirements, oceanographic determinants of demographic performance, ecological interactions with commercial fisheries, the extent, trends, processes and implications of hybridisation at Macquarie Island, and the status and trends in numbers of the threatened subantarctic fur seal. This dataset represents ARGOS tracking data of fur seals from Macquarie Island during 1997-1999. The tracking data are comprised of 28 data profiles. Taken from the abstract of the referenced paper: Antarctic Arctocephalus gazella and subantarctic Arctocephalus tropicalis fur seals breed sympatrically at Macquarie Island. The two species have different lactation strategies, the former rearing its pup in 4 months and the latter taking 10 months. The diet and at-sea foraging behaviour of these sympatric species was compared during the austral summer period when their pup rearing period overlapped. The prey of the two fur seal species was very similar, with fish dominating the diet. Themyctophid, Electrona subaspera, was the main prey item (93.9%) in all months of the study. There were no major differences in the diving behaviour between species. Both species foraged north of the island parallel to the Macquarie Ridge. Foraging activity was concentrated at two sites: (i) within 30 km north of the island; and (ii) at 60 km north. Most locations for overnight foraging trips were within 10 km of the colonies. The different lactation strategies of A. gazella and A. tropicalis allowed for flexibility in foraging behaviour. At Macquarie Island, the local marine environmental conditions have resulted in similar foraging behaviour for both species.

This dataset contains: 1) count data from a series of surveys of brown skua nest numbers and breeding success conducted from 2008/09 to 2017/18; 2) historic skua nest count data and concurrent estimates of rabbit abundance (1974/75 to 2009/10); 3) stable isotope data from feather samples taken from skua chicks during the 2017/18 season to compare stable isotope ratios between different feather types; 4) stable isotope data from feather samples taken from skua chicks from 2008/09 to 2017/18; 5) a small dataset of stable isotope data from skua prey tissue samples; 6) the nest locations of skuas surveyed in the seasons 2009/10, 2012/13 and 2017/18.
