title: Absorption coefficient spectra (median) of non-algal particles during POLARSTERN cruise PS99

description: Absorption coefficients (abs) and optical density (OD) by total particles, phytoplankton and non-algal particles (NAP) were measured with standard deviation (sd) estimated on water samples collected from underway AC-S flow-through system outflow and CTD. Measurements were performed using QFT-ICAM (Röttgers et al., 2016) as described in Liu et al. (2018) and Liu et al. (2019).1. About sampling:a) underway samples were collected from unfiltered AC-S outflow (depth: 11m); CTD samples with 5-6 depths were collected on upcast.b) vacuum pressure for filtration: maximum 200 hPac) samples were measured fresh (not preserved).d) blank filters were collected by soaking them in 0.2um filtered seawater.e) replicates were not collected.2. About measurements:a) Instrument: light source: UV-VIS lamp (CF-1000- HC lamp, Illumination Technology, USA); absorption meter: Quantitative Filter Technique - Integrating Cavity Absorption Meter (QFT-ICAM) (Röttgers et al., 2016) with 80 mm- diameter integrating sphere; detector: photodiode array spectrometer (AVASPEC-ULS2048-RS-USB2, Avantes, the Netherlands).b) wavelength range of scan and resolution: 313.5-875.7 nm, 0.3 nm.c) slit band width: 2 nm.d) sample filters were bleached with 10% sodium hypochlorite (NaClO) solution for the OD measurement of NAP.e) samples were measured for four times and bleached samples were measured twice.f) dark current and blank filters were measured and subtracted.3. About data analysis:a) interpolated wavelength range and resolution: 320-844 nm, 2nm.b) wavelength range for fluorescence correction: 670:800 nm.c) diameter of sample patch on GF/F filter: 2.133 cm.d) pathlength amplification factor (beta correction factor): 4.06 (Röttgers et al., 2016).e) no scattering correction for total particle absorption is applied; NAP absorption was adjusted with an offset in the range of 710-750 nm so that the median value of NAP absorption equals the median value of in total particle absorption in this spectral range. This adjustment is based on the assumption that phytoplankton pigments do not absorb in near-infrared (Neeley et al., 2018). This adjustment was not applied to NAP OD data.f) NAP absorption data from underway samples collected during 2016-06-17T21:20, 2016-06-18T00:26, 2016-06-18T03:19, 2016-06-18T06:38, 2016-06-15T12:12, and 2016-06-15T15:09 were missing. To calculate the corresponding phytoplankton absorption, the missing NAP data were taken the same as the ones from 2016-06-17T18:13, 2016-06-18T18:09, 2016-06-18T18:09, 2016-06-18T18:09, 2016-06-15T09:15, and 2016-06-15T09:15, respectively. However, this was not applied to NAP OD data.

title: X-ray µ-CT data reconstruction, image stacks of selected samples from IODP Site 385-U1546

description: This contribution comprises true-3D volume datasets (Digital drill cores), acquired by a X-ray Computed Microtomography (µ-CT) survey on selected drill core material recovered from Site U1546, Hole C, drilled by IODP Expedition 385 in the Guaymas Basin, Gulf of California (for more details see Teske et al., 2021). The four samples are igneous material from a single igneous 75 m thick sill intrusion. The samples were scanned as quarter cores and selected along the sill thickness to enable visualization of the main textural variations found along the sill (see Galerne et al., in Rev). The X-ray μ-CT scans were performed using the ZEISS Xradia 520 Versa system of the MAPEX Center for Materials and Processes at the University of Bremen, Germany. This µ-CT survey has been conducted as part of IODP Expedition 385 Post-cruise research led and secured by Christophe Galerne (German Research Foundation (DFG) funding priority program SPP 527. Project number 447431016). The samples were quarter cores or irregularly shaped pieces. The reconstructed image material has resolutions between 8.05 and 16.1 µm/voxel (depending on the sample size and geometry). The µ-CT-derived image volumes comprise the true 3-D spatial arrangement of fabric compounds in the rock. In the reconstructed 16-bit greyscale volume data, areas of highly attenuating phases (e.g. sulfides, calcite) are encoded in light grey values, whereas areas of low X-ray absorption are color-coded in dark grey (e.g. clays) or black (e.g. voids, cracks). In order to facilitate straightforward access to the digital drill core image material, the volume data is provided as a zipped stack of tif images. In addition, each digital drill core is characterized by three types of visualization: (i) shaded and classical texture-based volume rendering (volren), (ii) maximum intensity projection (volren-MIP): visualization of the highest intensity in a data volume along the current line of sight, and (iii) three perpendicular virtual cutting planes (3-slices). As an added value to the non-destructive visualization procedure, the reconstructed X-ray micro-CT scans of the studied drill core material provide volume reconstructions which can serve as digitypes that may be studied as digital facsimile without the necessity of consulting / modifying / destructive interactions of the actual type specimens (e. g. for investigations regarding the fabric relations). These image data can be used for quantitative 3D image analysis, e. g. to derive empirical relations between porosity, the extent of replacement of primary phases, and the distribution of secondary phases (and many more).

title: REVEALS land-cover reconstructions for Europe during the Late Pleistocene (75-15 ka BP)

description: We present the first pollen-based REVEALS land-cover reconstructions of Europe during the late Last Glacial period from Europe. The results are based on fossil pollen data from 61 sites in Europe and bordering regions, using 38 plant taxa in total. The reconstruction uses the "Regional Estimates of VEgetation Abundance from Large Sites"(REVEALS) model that factors in the relative pollen productivity (RPPs) and fall speed of pollen (FSP) (Sugita, 2007). All REVEALS estimates and their Standard Erorrs are given in proportions for each site in 1kyr time steps from 75 to 15 ka BP. Moreover, we provide the RPP and FSP table, which was adapted from Githumbi et al. (2022) and Serge et al. (2023). We also include REVEALS land-cover reconstructions of the same dataset, using the RPP compilation of Wieczorek & Herzschuh (2020) as well as optimized RPP data after Schild et al. (2024) to highlight the impact of different RPP data on REVEALS land-cover reconstructions.

title: Macroremain counts from borehole Sokli B series in Sokli (Finland) in 2002

description: This dataset provides absolute counts of botanical and zoological macro-remains obtained from the Early Weichselian sediment sequence retrieved from Sokli (Finland) in 2002. Counts per taxon are presented against sediment depth (m), and the volume of sediment used for each sample (ml³) is provided to allow the calculation of concentrations. For some taxa relative counts (Rel) are presented where: Rel.1 = Rare, less than 5 occurrences; Rel.2 = regular-mass occurrences. The macroremain dataset consists of a total of 90 samples and provides information on terrestrial and aquatic ecosystem dynamics (Helmens et al., 2012) and was used to reconstruct climate conditions (Väliranta et al., 2009). Macrofossil samples were prepared from subsamples of mainly ca. 10 ml³. The sediment was sieved using a 100 μm mesh under running water and the residue examined using stereo and high-magnification light microscopes. The volume of the sediment used for plant-macrofossil analysis was determined by displacement of water. It varied between 5 and 15 cm³ but was typically 10 cm³. The sediment was soaked in Na4P2O7.H2O (sodium pyrophosphate) solution to aid sediment disintegration. The sediment was sieved through a 100 um mesh and the residue was systematically examined at 10 magnification using a stereo-microscope. Critical identifications were made using a high-magnification light microscope. The analyses were performed in the laboratories of Stockholm University, Sweden.

title: Diatom counts from borehole Sokli B series in Sokli (Finland) in 2002

description: This dataset provides counts of diatom valves for the Early Weichselian sediment sequence retrieved from Sokli (Finland) in 2002. Counts per taxon are presented against depth (m); total sums for classes of diatoms (e.g. total benthic diatoms) are presented as well. The diatom dataset provides information on MIS 5c lake ecosystem dynamics (Helmens et al., 2012). A total of 10 samples were selected for diatom analysis. Diatoms were extracted from the sediment following the protocol presented by Battarbee et al. (2002). First, organic matter was oxidized in H2O2 in a water bath (at c. 100 °C). Subsequently, carbonates were removed by 10% HCl treatment (no visible reaction). Clay particles were decanted from 100 ml beakers after sedimentation overnight. Sand grains were removed after five seconds of sedimentation. The residue was mounted in Naphrax® and analysed under a light microscope with X1000 magnification using immersion oil. Flora used for species identification and information on ecological preferences are presented in Helmens et al. (2009). A minimum of 1000 diatom valves were identified from each of the 6 uppermost samples. The bottommost samples had low diatom concentration and total count sums vary between 4 and 112 in these samples. All analyses were performed in the laboratories Stockholm University, Sweden.

description: This dataset contains the values of dry weight biomass measured in 1436 samples of plankton size fractions sampled during the PELACUS spring cruises in the northwestern Iberian shelf and in adjacent waters of the southern Bay of Biscay. Plankton was collected by plankton nets of 30 cm diameter, 40 µm mesh size (fractions &lt;200 µm) and 50 cm diameter, 200 µm mesh size (fractions &gt;200 µm) by vertical hauls 0-100 m (or less if bottom depth &lt;100 m). Final size fractionation was made on board using mesh sieves (40, 200, 500, 1000, 2000, and 5000 µm mesh size). Samples were preserved frozen on board (-20°C) and subquently oven dried (60°C, 48 h) in the laboratory.
