    Radiogenic Nd isotope signatures of progressively leached dolostone grains from 4 sediment cores in the Labrador Sea (2022)
    PANGAEA
    Details
    Publication Date: 2023-06-27
    Description: This dataset includes the results of the analysis of 4 marine sediment downcore records recovered from the Labrador Sea: core MD99-2227 (58° 12.38 N, 48° 22.22 W, 3460 m); core HU08-029-004 (61°27.49 N, 58°02.11 W, 2674 m); HU84-030-021 (58°22.06 N, 57°30.42 W, 2853 m); core HU91-045-094,(50°12.26 N, 45°41.14 W, 3448 m). Analysis includes measurement of the radiogenic Nd isotope signatures progressively leached dolostone grains, picked from wet-sieved 〈 63µm sediment fraction of marine sediment downcores. The downcore records were sampled with resolution of about 1 kyr and cover roughly the last 33 ka.

    Biogenic opal record of gravity core MSM45_19-2 (2022)
    PANGAEA
    Details
    Publication Date: 2024-02-21
    Description: Biogenic opal (BSi) concentrations were analysed as indicator for past primary productivity on gravity core MSM45_19-2 from the northern Labrador Shelf. Gravity core MSM45_19-2 was obtained during R/V Maria S. Merian expedition MSM45 (58°45.68'N, 61°56.25'W, water depth: 202 m) in 2015 (Schneider et al., 2016). Biogenic opal was determined at Dalhousie University following the method of (Mortlock and Froelich , 1989). Briefly, amorphous silica was extracted from ca. 20 mg subsamples using a 2 M Na2 CO3 solution at 85°C for 5 h, followed by the measurement of dissolved silica concentrations by molybdenum blue spectrophotometry.
