The associated NCEI study type is Paleoceanography. The data include parameters of paleocean (population abundance) with a geographic location of Indian Ocean. The time period coverage is from 55000000 to 35000000 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Records of past climate and ocean circulation derived from marine sediments. Parameter keywords describe what was measured in this dataset.

Data are raw nannofossil counts from 184.49-422.00 msbf (Core 3-4-49cm to 29-1-50cm). Assemblage data was collected by first identifying 500 specimens to species level, except members of Pontosphaeraceae and Syracosphaeraceae, which were rare and sporadic through the section. Additionally, two long traverses were examined to identify rare specimens, which were given a value of 1 and added to the total. This data was used to convert all species and genera to percent abundance for further analysis. Detailed site information can be found in Shamrock and Watkins (2012), or from Leg 122 Initial Reports (Haq et al. 1990) and Scientific Results (Rad et al. 1992). The vast majority of original taxonomic references can be found in Perch-Nielsen (1985) and Bown (1998). Samples were supplied by the International Ocean Drilling Program (IODP). ABSTRACT SUPPLIED BY ORIGINATOR: A relatively complete section of Eocene (~33.9-55.8 Ma) pelagic chalk from offshore northwestern Australia was used to analyze range and abundance data of ~250 Eocene species to test the efficacy of the existing CP (Okada and Bukry 1980) and NP (Martini 1971) biostratigraphic zonation schemes. Changes in nannofossil diversity, abundance, and community structure were monitored through several Eocene paleoenvironmental events, as identified by changes in d13C and d18O data, to examine variations in surface water conditions. Major changes in nannofossil assemblages, as indicated by dominance crossovers, correspond to paleoenvironmental shifts such as the PETM (Paleocene-Eocene thermal maximum) and the EECO (Early Eocene climatic optimum). This research also provides systematic paleontology and range data for one new genus (Hexadelus) and eight new species or variants (Calcidiscus ellipticus, Cruciplacolithus nebulosus, Cruciplacolithus opacus, Cyclicargolithus parvus, Hexadelus archus, Hayella situliformis var. ovata, Markalius latus, Pedinocyclus annulus) and addresses several taxonomic issues in other Eocene species.
