title: Macroscopic charcoal record from the sediment core EN21421-2

description: Macroscopic charcoal records and radiocarbon age dating information of sediment cores from eight lakes in central and eastern Yakutia. Sediment cores were obtained during fieldwork in August 2021, jointly organized by the Alfred Wegener Institute and the North-Eastern Federal University of Yakutsk. Charcoal data includes the total amount of particles per sample as well as their respective distributions in size classes (150-300 µm, 300-500 µm, &gt; 500 µm), morphotype categories, and (for some of the records) average particle length-to-width ratios. More detailed information about the data and an approach to age-depth modelling can be found in the research paper (in preparation). Details of fieldwork in 2021 is available in the corresponding expedition report (Morgenstern et al., 2023).

title: Major element composition of glass shards from 1458/59 CE cryptotephra in VK22 firn core

description: We present the major element compositions (SiO₂, TiO₂, Al₂O₃, FeO, MgO, CaO, Na₂O, and K₂O) of unpolished micron-sized volcanic glass shards within cryptotephra layers associated with the prominent 1458/59 CE sulfate peak in a shallow firn core (VK22) drilled near the Russian Antarctic Vostok Station in East Antarctica. The measurement was performed by a quantitative scanning electron microscopy–energy dispersive X-ray spectrometry (SEM–EDX) technique using a reverse Monte Carlo simulation combined with a robust successive approximation algorithm, effectively accounting for both matrix and geometric effects and consequently contributing to an accurate determination of characteristic X-ray intensities of specific elements in unpolished glass shards. The results show a bimodal composition of glass shards, corresponding to dacitic and rhyolitic types.

title: Dissolved munition compounds in the water column of southwestern Baltic Sea during POSEIDON cruise POS530 in October 2018

description: Cruise POS530 (R/V Poseidon) sampled the water column throughout German territorial waters of the southwest Baltic Sea during 01-21 October 2018. The current dataset contains concentrations of dissolved munition compounds from Niskin bottle rosette casts between sea surface and seafloor. Vertical sampling resolution varied among stations, with a maximum of 9 sampling depths. Dissolved explosives in the samples were measured following Gledhill et al. (2019). Briefly, discrete samples (1 L) were preconcentrated onboard using solid-phase extraction. Target compounds were eluted with acetonitrile, further concentrated by evaporation, and measured by ultra-high performance liquid chromatography and high resolution heated electrospray ionization mass spectrometry.

title: Total carbon, total organic carbon, and total inorganic carbon (solid-phase discrete samples) from IODP Hole 389-M0096A

description: Total carbon (TC), total organic carbon (TOC), and total inorganic carbon (TIC) content from solid-phase discrete samples from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). The offshore phase of this expedition took place between 2023-08-31 and 2023-10-31 onboard multipurpose vessel MMA Valour sailing from and to Barbers Point Harbor, Hawai'i, USA, followed by the onshore phase from 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. During the onshore phase a set of solid-phase samples were taken from the work halves of core sections, with a volume of approx. 10 cubic centimeters each, were taken with the purpose to be later on split into aliquots for the following three analyses: X-ray diffraction, carbon and X-ray fluorescence. Bulk samples were subsequently freeze-dried, ground and homogenized to a fine powder (&lt;20 µm particle size) by ECORD Science Operator staff using a pestle and an agate mortar or a ball mill. Sample aliquots of approx. 100 mg (TC) and 1 g (TOC) were processed through a CS744 LECO carbon-sulfur analyzer to obtain the respective concentrations. TIC was calculated as the difference between TC and TOC.For further methodological information see methods chapter in Webster, J.M. et al., 2025 https://doi.org/10.14379/iodp.proc.389.2025
