    Diatom percentage abundances and sea surface temperature reconstruction for core AI07-06G, from Trinity Bay, Newfoundland (2021)
    PANGAEA
    Details
    Publikationsdatum: 2023-11-03
    Beschreibung: Due to the shortness of available records, the longterm patterns of climate variability in the Labrador Sea and Newfoundland region are not clear. Here, a diatom-based reconstruction of summer sea-surface temperature (SST) developed from Trinity Bay, Newfoundland, provides insight into variations of SST since 7.2 cal ka BP in the southwestern Labrador Sea. The results show that the Holocene Thermal Maximum (HTM) lasted until c. 5.2 cal ka BP, which was followed by a gradual cooling trend overprinted by centennial temperature fluctuations of 1-2°C.

    Benthic foraminiferal abundances, stable isotopes and XRF data from the Northeast Greenland shelf, sediment core DA17-NG-ST7-73G (2021)
    PANGAEA
    Details
    Publikationsdatum: 2023-11-09
    Beschreibung: We carried out benthic foraminiferal assemblage-, stable isotope- and XRF analyses of a marine sediment core retrieved from the Northeast Greenland shelf (core DA17-NG-ST7-73), which provided a multiproxy reconstruction of Holocene paleoceanographic conditions. The results reveal significant variations in the water masses and thus, in the strength of the East Greenland Current over the last ca. 9.4 ka BP.

    Diatom percentage abundances and sea surface temperature reconstruction for core DA12-11/2-GC01 from the Iceland Basin (2021)
    PANGAEA
    Details
    Publikationsdatum: 2023-12-08
    Beschreibung: Here, we present datasets of diatom abundance and a diatom-based sea surface temperature reconstruction from the Iceland Basin. The 419.5 cm long marine sediment core DA12-11/2-GC01 was recovered in September 2012 by the Danish R/V Dana using a gravity corer. The core was taken from a location at the northern edge of the Gardar Drift and the eastern edge of the Björn Drift in the Iceland Basin (61.36.536 °N, 20.42.164 °W) at a water depth of 2120 m. Diatoms were analysed at 5 cm intervals over the upper 2 m of core, representing the period 6100-0 cal years BP, with chronological constraints provided by 6 radiocarbon dates. Diatoms were analysed using standard procedures, including the identification and counting of a minimum of 300 diatom per sample, which allowed calculation of the percentage abundances of different species. These abundances were converted into estimates of sea surface temperature using the weight averaging partial least squares transfer function approach.
