    The inorganic carbonate system of surface sediment samples and of sediment core PS75/104-1 (2021)
    PANGAEA
    Details
    Publication Date: 2023-05-08
    Description: Here we show how surface sediment samples from ten locations from the Pacific Sector of the Southern Ocean and the downcore LGM to Holocene carbonate system of intermediate water sediment record PS75/104-1 offshore New Zealand. We measured foraminiferal B/Ca ratios via laser ablation-inductively coupled-mass spectrometry (LA-ICP-MS) and used the calibration of Yu et al. (2013) for Cibicidoides wuellerstorfi and Ronge et al. (under review) for C. dispars. Measurements were conducted at the GEOMAR in Kiel in 2013.

    Characteristics, elevations and ages of various mid-late Holocene features collected from twelve islands in French Polynesia (2021)
    PANGAEA
    Details
    Publication Date: 2024-01-25
    Description: Characteristics, elevations and ages of 165 samples from various mid-late Holocene features, such as in situ Porites microatolls, in situ reef flats, conglomerates and reworked reef blocks, collected from twelve islands in French Polynesia. This table complements the database on which the mid-late Holocene sea-level curve has been initially reconstructed (Hallmann et al., 2018). Δ modern-fossil represents the difference in elevation between modern and Holocene microatolls at the same study site and in a similar environment (maximum vertical error is of ± 2 cm). NGPF = altimetric reference of French Polynesia. The elevations have been corrected for subsidence based on rates of 0.14 mm/yr for Moorea, 0.05 mm/yr for Bora Bora and Tahaa as well as 0.03 mm/yr for Maupiti, the Gambier Islands and Raivavae. Error values for ages and elevations are 2-sigma. Uncertainties for measured elevations related to NGPF are ± 14 cm for samples from Bora Bora, Maupiti, Raivavae, Tikehau and the Gambier Islands; ± 22 cm for samples from Fakarava, Hao, Makemo, Manihi, Moorea, Rangiroa and Tahaa. Uncertainties for estimated elevations are ± 10 cm for Δ modern-fossil and ± 22 cm for NGPF elevations.

    Uranium/Thorium isotopic composition of various mid-late Holocene features collected from twelve islands in French Polynesia (2021)
    PANGAEA
    Details
    Publication Date: 2024-01-25
    Description: Uranium/Thorium isotopic composition of 165 samples from various mid-late Holocene features, such as in situ Porites microatolls, in situ reef flats, conglomerates and reworked reef blocks, collected from twelve islands in French Polynesia. Recommendations of Dutton et al. (2017) were followed for the presentation of U/Th age data. For each parameter, the first column contains the value and the second column the statistical error. All statistical errors are two standard deviations of the mean (2σ mean). All samples have been corrected for initial 230Th by using a 230Th/232Th activity ratio of 0.66 ± 0.2 (Fietzke et al., 2005). Non-reported data consist of 230Th/232Th ratios which became negative due to background corrections. 238U Concentrations are not corrected for the background.

    B/Ca and carbonate ion concentrations of South Pacific Cibicidoides dispars (2021)
    PANGAEA
    Details
    Publication Date: 2024-07-01
    Description: Here we show surface sediment samples from ten locations from the Pacific Sector of the Southern Ocean (~44°S-48°S; ~174°E-116°W). We measured foraminiferal B/Ca ratios via laser ablation-inductively coupled-mass spectrometry (LA-ICP-MS) on Cibicidoides dispars, a species that is abundant in most samples of the Pacific sector of the Southern Ocean. Measurements were conducted at the GEOMAR in Kiel in 2013.
