Survey data collected from Core E53-10, located on the edge of the South Tasman rise
Australian Ocean Data Network (AODN)Most globally linked climatic records dealing with continuous longterm change are derived from the ocean sea-floors where sedimentation of microplankton is accumulated on a time scale of several centimetres per 1000 years. Variations in microfossil records…

Historical February / September sea-ice concentration and annual sea-ice cover estimation at the location of core MD88-787 in the Southeast Indian Ocean
Australian Ocean Data Network (AODN)Variations in microfossil records in sediments over time are used as proxies for changes in the ocean. One important record determined from microfossils is sea-ice cover which influences, and is influenced by, wind and ocean circulation, atmospheric…

Diatom recovery from core MD88-787: Raw counts
Australian Ocean Data Network (AODN)Core MD88-787 was recovered during the French ASPARA IV cruise in 1988, aboard the Marion Dufresne. The core was located on the Tasman Fracture Zone of the Mid-Ocean Ridge, within the Polar Front Zone. A total of 69 diatom species and taxa were recorded in…

Historical February Sea-Surface Temperature Estimates Utilising Diatom Transfer Functions with Core MD88-784
Australian Ocean Data Network (AODN)The purpose of this study was to estimate past sea-surface temperature in the Southeast Indian Ocean. The accumulation of diatom microplankton assemblages in sediments being the proxy for these records of climatic change. A transfer function is a mathematical…

Oxygen-isotope records, age-model results and sedimentation rates of core MD88-779
Australian Ocean Data Network (AODN)Core MD88-779 was taken during the 1988 French ASPARA IV cruise in the South East Indian Ocean aboard the Marion DuFresne. The core was situated on the South Tasman Rise (47º50.690S, 146º32.750E) at a depth of 2260m. Although the core recovered was 6.7m long,…

Antarctic Diatom Database (based on 115 surface samples)
Australian Ocean Data Network (AODN)All the available data sets containing diatom counts were compiled. These data sets were the 166 database used by Pichon et al. (1992), new data gathered separately by Dr Pichon (1994) and the author (L. Armand-1997), and Abbott's (1973) southeast Indian Ocean…

Raw counts of diatom species in 18 surface samples collected during the French PACIMA- and Antarctic CRC (South Tasman Rise)- cruise missions
Australian Ocean Data Network (AODN)Diatom distributions in the polar regions have been attributed to physical and biological processes. To contribute to an existing diatom database (Pichon et al. 1992), 18 sediment surface samples were taken from the French PACIMA- and Antarctic CRC (South…
