Data have been quality checked and are considered good. 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. The fields in this dataset are: Latitude Longitude Species Date Haul Number Time Depth (m) Tow distance Wire out Tow Speed (knots) Headline height (m) Headline width (m) Gear Comments Fishing Ground Fishery Traps Line Hooks Magazines Fish length Otoliths Scale sample Fish Weight Stomach Gonads Stomach contents
