    X-ray diffraction data of powder drilled from the shell of A. benedeni benedeni specimen SG-125 (2022)

    Details
    Publikationsdatum: 2023-08-18
    Beschreibung: This dataset contains X-ray diffraction data of powder drilled from the shell of A. benedeni benedeni specimen SG-125. This measurement was carried out in order to determine whether the originally aragonitic shell of this specimen contained any calcite of diagenetic origin. The spectrum of this specimen was compared to that of a modern aragonitic shell measured in-house (XRD_Fresh_Aragonite_Cerastoderma_edule.csv), and a calcite mineral from an external database (RRUFF database, ID R040070; Lafuente et al. 2015). The bivalve shells were collected in 2013 from a shell bed at the top of the Oorderen Member of the Lillo Formation of the Pliocene in Belgium. The collection site was a construction-related temporary outcrop at the Deurganck Dock Lock (now Kieldrecht Lock) in the city of Antwerp, located at 51°16′44″N 4°14′52″E. X-ray diffraction analysis was carried out in spring 2021 at the department of Earth Sciences at Utrecht University, the Netherlands, on a Bruker D8 diffractometer that was calibrated with a corundum crystal. Measurement conditions were as follows: 40 kV voltage, 40 mA current, 1.5418 Å (CuKα) radiation, 0.165 mm divergence slit, 2.5° primary soller slit, no secondary soller slit, 15-70° 2theta measuring range, 0.02° 2theta step-size, 0.85 s counting time, 15 rpm sample rotation. Reported are the angle (in degrees 2theta) and the corresponding intensity (in counts per second).

    Beschreibung: This dataset (XRF_Benedeni_benedeni_SG-125_126_127_crosslines_cal.csv) contains micro-X-ray fluorescence elemental data of the shell of A. benedeni benedeni specimens SG-125, SG-126, and SG-127. The bivalve shells were collected in 2013 from a shell bed at the top of the Oorderen Member of the Lillo Formation of the Pliocene in Belgium. The collection site was a construction-related temporary outcrop at the Deurganck Dock Lock (now Kieldrecht Lock) in the city of Antwerp, located at 51°16′44″N 4°14′52″E. These measurements were carried out in order to screen for diagenetic alteration, which results in enrichment of certain elements (e.g., Fe and Mn). The specimens were measured in spring 2021 at the Analytical, Environmental, and Geochemistry Research Group (AMGC) of the Vrije Universiteit Brussel, Belgium), on a Bruker M4 Tornado µXRF scanner. This instrument is equipped with a 30 W Rh anode metal-ceramic X-ray tube operated at 50 kV and 600 µA, and polycapillary lens focussing. The measurement was carried out following the methods described in de Winter and Claeys (2017) and Kaskes et al (2021), and consisted of multiple line scans oriented perpendicular to the growth direction. Also provided is an image file (XRF_Benedeni_benedeni_crosslines_locations.png) which shows the location of these line scans on the shell cross sections.

    CO2 and inorganic nutrient enrichment affect the performance of a calcifying green alga and its noncalcifying epiphyte (2015)
    PANGAEA
    In:  Supplement to: Hofmann, Laurie C; Bischof, Kai; Baggini, Cecilia; Johnson, Andrew; Koop-Jakobsen, Ketil; Teichberg, Mirta (2015): CO2 and inorganic nutrient enrichment affect the performance of a calcifying green alga and its noncalcifying epiphyte.

    Beschreibung: Ocean acidification studies in the past decade have greatly improved our knowledge of how calcifying organisms respond to increased surface ocean CO2 levels. It has become evident that, for many organisms, nutrient availability is an important factor that influences their physiological responses and competitive interactions with other species. Therefore, we tested how simulated ocean acidification and eutrophication (nitrate and phosphate enrichment) interact to affect the physiology and ecology of a calcifying chlorophyte macroalga (Halimeda opuntia (L.) J.V. Lamouroux) and its common noncalcifying epiphyte (Dictyota sp.) in a 4-week fully crossed multifactorial experiment. Inorganic nutrient enrichment (+NP) had a strong influence on all responses measured with the exception of net calcification. Elevated CO2 alone significantly decreased electron transport rates of the photosynthetic apparatus and resulted in phosphorus limitation in both species, but had no effect on oxygen production or respiration. The combination of CO2 and +NP significantly increased electron transport rates in both species. While +NP alone stimulated H. opuntia growth rates, Dictyota growth was significantly stimulated by nutrient enrichment only at elevated CO2, which led to the highest biomass ratios of Dictyota to Halimeda. Our results suggest that inorganic nutrient enrichment alone stimulates several aspects of H. opuntia physiology, but nutrient enrichment at a CO2 concentration predicted for the end of the century benefits Dictyota sp. and hinders its calcifying basibiont H. opuntia.

    Electron backscatter diffraction maps of thin sections of A. benedeni benedeni specimens SG-125, SG-126, and SG-127 (2022)

    Publikationsdatum: 2024-04-20
    Beschreibung: This dataset (.crc and .cpr files) contain electron backscatter diffraction maps of thin sections of A. benedeni benedeni specimens SG-125, SG-126, and SG-127. Also included are .BMP files for each map. The bivalve shells were collected in 2013 from a shell bed at the top of the Oorderen Member of the Lillo Formation of the Pliocene in Belgium. The collection site was a construction-related temporary outcrop at the Deurganck Dock Lock (now Kieldrecht Lock) in the city of Antwerp, located at 51°16′44″N 4°14′52″E. These measurements were carried out in order to determine the microstructures of the shells of A. benedeni benedeni, as well as to screen for minor diagenetic alterations. The specimens were measured in spring 2021 at Department of Earth Sciences of Utrecht University, the Netherlands, on an Oxford Instruments Symmetry EBSD detector attached to a Zeiss Gemini 450 SEM. Thin sections of the samples were mechanically polished with 0.3 µm aluminium oxide suspension and finished with chemical Syton® polish. The thin sections were covered with a thin (several nm) carbon coating to keep charge build-up during the measurements at a minimum.

    Beschreibung: This dataset contains oxygen and carbon isotope data of the shells of A. benedeni benedeni specimens SG-126 and SG-127, as well as two in-house standards (Naxos, Kiel-carbonate). These measurements were carried out in order to establish a sclerochronological record of year-by-year shell growth. The bivalve shells were collected in 2013 from a shell bed at the top of the Oorderen Member of the Lillo Formation of the Pliocene in Belgium. The collection site was a construction-related temporary outcrop at the Deurganck Dock Lock (now Kieldrecht Lock) in the city of Antwerp, located at 51°16′44″N 4°14′52″E. Oxygen and carbon stable isotopes were measured in spring 2021 at the department of Earth Sciences at Utrecht University, the Netherlands, on a Thermo Scientific GasBench II gas preparation system coupled to a Thermo Scientific MAT 253 isotope ratio mass spectrometer and using a LIDI workflow. The dataset includes raw data and corrected values, and final values are reported relative to the Vienna Pee-Dee Belemnite (VPDB) standard.
