    Geochemical data from loess records at the archaeological site Kammern-Grubgraben, Lower Austria (2022)
    PANGAEA
    Details
    Publication Date: 2023-10-14
    Description: Two loess sections from the Upper Palaeolithic site of Kammern-Grubgraben (Lower Austria) were analysed to test geochemical proxies, as well as radiocarbon data of different components for their reliability and consistency in an archaeological context. Only a reliable basal age (28.9  27.8 ka cal BP) was obtained from charcoal fragments derived from a tundra gley underlying the archaeological horizons and assigned to Greenland Interstadials 3 or 4. Grain size, organic and inorganic geochemistry, and stable isotopes of the fine organic fraction (13Corg) and of rhizoconcretions (13C, 18O) were analysed to provide information on palaeoenvironmental conditions. Low-resolution geochemical and sedimentological analyses document a humidity-related variability, while 13Corg values indicate a predominant C3 vegetation. High-resolution elemental variations derived from X-ray fluorescence scanning exhibit increasing Ca and decreasing Fe and Ti values indicating drier conditions towards the top. Secondary pedogenic carbonate concretions provide post-sedimentary (Holocene) ages and are not suitable for assessing climate and environmental changes for the Palaeolithic.

    Stable isotope records of sei whale baleens from Chilean Patagonia (2019)
    PANGAEA
    Details
    Publication Date: 2024-02-05
    Description: The datafile includes nitrogen and carbon isotope analyses of seven baleen plates from six individuals of sei whales (Balaenoptera borealis) from the Chilean-Patagonian fjord area in 0.5 cm resolution. The baleens are from dead carcasses all stranded, except of one, after a mass mortality event in 2016 (Häussermann et al. 2017; https://doi.org/10.7717/peerj.3123 ). Carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotope variations in baleen plates of sei whales (Balaenoptera borealis) stranded after a mass mortality event in Chilean Patagonia were analyzed to assess potential dietary and migratory patterns. Carbon and nitrogen isotope ratios of seven baleens from six individuals were analyzed. The δ¹³C values ranged from -19.1 to -15.9 ‰ and the d15N values from 8.7 to 15.4 ‰. Variations of up to 2.9 ‰ for δ¹³C and 5.3 ‰ for δ¹⁵N were observed within one baleen. Carbon and nitrogen isotope records of each baleen were significantly correlated and showed recurring oscillations confirmed by wavelet analyses. Oscillations slightly differed in periodicity indicating variable baleen growth rates between 10.0 and 16.5 cm yr-1. Food sources of the whales are discussed in terms of available isotope data for potential prey taxa and potential migratory behavior on the basis of latitudinal isotope gradients of particulate organic matter. Cyclicity could be explained by regular migrations of the sei whales from subtropical calving areas to high-latitude foraging grounds. δ¹⁵N records of baleens differed between individuals eventually pointing to diverse feeding and migratory preferences among sei whale individuals.
