47. Schoon, PL; Heilmann-Clausen, C; Pagh Schultz, B et al. (2013): Stable carbon isotope values of TOC and biphytanes for three PETM sections in Denmark and for the ETM2 section of iODP Site 302-M0004A from the Lomonosov Ridge

    Abstract:

    The Paleocene-Eocene Thermal Maximum (PETM; ~56 Ma) and Eocene Thermal Maximum 2 (ETM2; ~53 Ma) are geological short (<200,000 years) episodes of extreme global warming and environmental change. Both the PETM and ETM2 are associated with the injection of 13C-depleted carbon into the ocean-atmosphere system as revealed through a globally recognized carbon isotope excursion (CIE) and massive dissolution of deep sea carbonate. However, the magnitude of these CIEs vary with the type of fossil matter, i.e. multiple carbonate phases, bulk organic matter, and terrestrial and marine biomarker lipids, making it difficult to constrain the actual CIE in atmospheric and oceanic carbon pools. Here we analyzed the stable carbon isotopic composition (d13C) of glycerol dibiphytanyl glycerol tetraether lipids (GDGTs) derived from marine Thaumarchaeota in sediments deposited during the PETM in the North Sea Basin and ETM2 in the Arctic Ocean.

48. Papadomanolaki, NM; Sluijs, A; Slomp, CP (2021): Major element composition of IODP Hole 302-M0004A

    Abstract:

    This dataset belongs to a data compilation that contains total organic carbon content, calcium carbonate content and concentrations for major elements, covering the Paleocene-Eocene Thermal Maximum, for the following sites: Forada Site, Italy, IODP 302 Site M0004, IODP 342 Site U1403, Bass River Site, US, Lodo Gulch Site, US, ODP 121 Site 752, and ODP 189 Site 1172. The data were generated in the period between 2014 – 2017 at the GeoLab of Utrecht University in The Netherlands. Organic carbon and CaCO3 were calculated following decalcification and C/N analysis with a Fisons Instruments CNS NA 1500 analyzer. Major elements were measured using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES, Perkin Elmer 9224 Optima 3000) following total destruction with hydrogen fluoride. These data are used to determine the redox conditions at the sites mentioned above.

49. St. John, KEK (2010): (Table 1) Summary of general lithology in IODP Exp302 cores

    Abstract:

    The Cenozoic ice-rafted debris (IRD) history of the central Arctic is reconstructed utilizing the terrigenous coarse sand fraction in IODP 302 cores from 0 to 273 meters composite depth. This Holocene - middle Eocene quantitative record of terrigenous sand accumulation on the Lomonosov Ridge, along with qualitative information on grain texture and composition, confirms the interpretation that ice initiation (sea ice and glacial ice) occurred ~46 Ma in the Arctic, and provides a long-term pattern of Arctic ice expansion and decay since the middle Eocene. IRD mass accumulation rates range from 0 to 0.13 g/cm2/ka in the middle Eocene and from 0 to 0.36 g/cm2/ka in the Neogene. IRD mass accumulation rate (MAR) maxima in the Miocene and Pliocene cooccur with either glacial initiation or intensification in the sub-Arctic. […]

50. Onodera, J; Takahashi, K; Jordan, RW (2010): (Table 2) Similarity Indexes (Pearson's correlation coefficient) of the silicoflagellate assemblages of IODP Exp302

    Abstract:

    The silicoflagellate and ebridian assemblages in early middle Eocene Arctic cores obtained by IODP Expedition 302 (ACEX) were studied in order to decipher the paleoceanography of the upper water column. The assemblages in Lithologic Unit 2 (49.7-45.1 Ma), one of the biosiliceous intervals, were usually endemic as compared to the assemblages that occurred outside of the Arctic Ocean. The presence of these endemic assemblages is probably due to a unique environmental setting, controlled by the degree of mixing between the low-salinity Arctic waters and relatively high salinity waters supplied from outside the Arctic Ocean, such as the Atlantic and possibly the Western Siberian Sea. Using the basin-to-basin fractionation model, the early middle Eocene Arctic Ocean corresponds to an estuarine circulation type, which includes the modern-day Black Sea. […]
