All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description

Metadata record for data from ASAC Project 2388
See the link below for public details on this project.

---- Public Summary from Project ----
The HIMI Ecosystem Project is 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 will include 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 will be involved.

These data were collected on Aurora Australis voyage 4 2004 ('HIPPIES'). The data are stored in a Microsoft Access 97 file. The data includes sampling information for trawls using an IYGPT (International Young Gadoid Pelagic Trawl) Net and RMT 8 (8 square meter Rectangular Midwater Trawl) Nets. Sampling data, including location and time, are stored in the 'Hauls' table. Data from the analysis of the contents of each trawl, including species identifications, mass and counts of each taxon of mesopelagic fish and zooplankton are stored in the 'Bycatch' table. Weights, lengths and other biological data collected from individual mesopelagic fish are stored in the 'Fish Data' table. On opening the file the Haul form launches automatically giving access to the data.
