    Sortable silt paleo-current proxies of sediment core NAP 63 - 1 (2021)
    PANGAEA
    Details
    Publication Date: 2023-02-07
    Description: We present sortable silt mean grain size (a proxy for near-bottom current speed) from a sediment core retrieved at the modern core of Intermediate Water Brazil Current (IWBC), that carries Antarctic Intermediate Water (AAIW) to the north spanning the last 80 kyr. The sortable silt was measured using a Malvern Mastersizer 2000 Laser Analyzer and the data presented is the average of three different measurements per sample.

    Morphological measurements of coccoliths from surface samples of R/V SONNE cruise SO95 (2023)
    PANGAEA
    Details
    Publication Date: 2023-05-09
    Description: The dataset compiles morphological measurements of coccoliths (Gephyrocapsa spp.) from one sample from the Western Equatorial Pacific. The morphological measurements were applied to evaluate coccolithophore preservation aspects under different dissolution intensities in a laboratory experiment. For the dissolution experiment, we added different amounts of Calgon solution (0, 0.4, 0.8, 2, 4, and 6 ml) in subsamples prepared from one sediment sample (ODP 807A-2H2W57-59 cm). The length, volume, area, and mass were obtained using the C-Calcita software from images taken under a cross-polarized microscope (Zeiss AX10). Thickness and the shape factor ks were calculated. The columns include the sample name, how much Calgon was added into sediment suspension, the number of coccoliths measured per sample, length, mean ks shape factor and standard deviation of mean ks/mean ks.

    End member modelling of grain size data of sediment core NAP 63 - 1 (2021)
    PANGAEA
    Details
    Publication Date: 2023-07-05
    Description: We present the Grain-size end-member modeling results from a record retrieved at the modern core of Intermediate Water Brazil Current (IWBC), which carries Antarctic Intermediate Water (AAIW) to the north spanning the last 80 kyr. The end-member model was performed with the BASIC-EM (BasEMMA) using grain-size data measured with a Malvern Mastersizer 2000 Laser Analyzer. The number of end-members considered was determined by analyzing the inflection curve of the progressive coefficients of determination.

    Coccolith dissolution experiment from one sample of ODP Hole 130-807A (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-11
    Description: The dataset compiles morphological measurements of coccoliths (Gephyrocapsa spp. and Emiliania huxleyi, 〉2µm) from surface samples of the South China Sea retrieved along a depth gradient (629 – 3809 m) during the R/V Sonne cruises (SO-95). The morphological attributes (length, volume, thickness, and ks shape factor) from the Noelaerhabdaceae group (Emiliania huxleyi and Gephyrocapsa spp) were applied to evaluate coccolithophore calcification and preservation aspects. The length, volume, area, and mass were obtained using the C-Calcita software from images taken under a cross-polarized microscope (Zeiss AX10). Thickness and the shape factor ks were calculated. The columns include station names, Longitude, Latitude, Depth (m), number of coccoliths measured per sample, mean ks shape factor, thickness, length, volume, mass, and standard deviation of mean ks/mean ks.
