title: X-ray fluorescence (Ti/Ca and Zr/Rb ratios) in sediment core MD99-2198 (0-125 ka)

description: X-ray fluorescence data (Ti/Ca and Zr/Rb ratios) were obtained using the Aavatech XRF Core Scanner at University Kiel in two runs (10 kv, 750 mA, 10 seconds and 30 kv, 2000 mA, 20 seconds). Elemental intensities were measured every 1 cm between 0-18.83 m and 0.5 cm between 18.84-22 m (revised depth). Note that the original core depth scale in core MD99-2198 was modified by excluding two intervals (10.06-10.24 m and 13.78-14.30 m), representing episodes where the core was ripped apart, as could be concluded on the basis of large increases in porosity.
description: Revised depth: Intervals between 10.06-10.24 m and 13.78-14.30 m where the core was ripped apart were excluded.

title: Bulk organic matter composition, n-alkane distribution patterns, and compound-specific stable isotope compositions of modern surface sediments and plants of South Africa's largest freshwater wetland

description: Surface sediments (n=41) reflecting modern times (uppermost 10 cm) were collected during a November/December 2018 field campaign along the course of the Mkhuze River and a transect into Lake St. Lucia (KwaZulu Natal Province, South Africa). In addition, plant species (n=10) were collected based on previous reports of dominant vegetation communities and local occurrences. All samples were extracted soon after with a mixture of dichloromethane and methanol (9:1), purified, and fractionated. The apolar fraction was finally analyzed for its n-alkane concentrations and corresponding compound-specific carbon and hydrogen isotope compositions. Sub-samples of the surface sediments were also analyzed for (i) organic matter content (total organic carbon) and composition (d13C, carbon-to-nitrogen ratio) after decalcification, and (ii) for thermal indices (Hydrogen Index, R-index, I-index) using Rock-Eval analyses. The study's objective was to evaluate the most extensive freshwater wetland system in South Africa regarding its current condition and functioning by identifying the origin and transport pathways of sedimentary organic matter.

title: Plio-Pleistocene scanning x-ray fluorescence (XRF) data from ODP Site 967, Eastern Mediterranean

description: Mediterranean sediments record past changes in North African aridity/humidity changes (so-called 'Green Sahara periods') on orbital timescales. These changes are reflected in the alternating accumulation of organic carbon-rich and aeolian dust enriched sediments, and negative stable oxygen isotope excursions. Here we document these changes over the past 5 million years using scanning x-ray fluorescence (XRF) of ODP Site 967 sediments, measured with a 3rd generation Avaatech XRF core scanner. Element counts were converted into element concentrations for Al [ppm], Si [ppm], S [ppm], K [ppm], Ca [ppm], Ti [ppm], Fe [ppm], Sr [ppm], Zr [ppm] and Ba [ppm], based on a multivariate log-ratio calibration.

title: XRF data from Tenaghi Philippon (Greece) spanning the past 500 kyrs

description: Palynological and X-Ray fluorescence (XRF) data from Tenaghi Philippon (Greece) were generated to reconstruct climate and environmental changes in the Mediterranean region during the past 500 kyrs. The analyses were carried out on peat drillcores from two locations, i.e., TP-2005 – 40° 58' 24.0” N, 24° 13' 25.2” E; TP-2009 – 40° 57' 39.5” N, 24° 16' 03.1” E. A total of 2347 palynological samples, taken every 2-5 cm from the 4–91 m composite depth, were prepared using standard palynological techniques. Pollen percentages were calculated on the number of pollen grains from terrestrial plants excluding Cyperaceae and Poaceae because of their natural over-representation at Tenaghi Philippon. The palynological results present relative abundances of tree pollen, tree pollen without Pinus, temperate taxa, Mediterranean taxa, montane taxa, pioneer taxa, shrubs, steppic taxa, herbs, helophytes, sum of Poaceae and Cyperaceae, aquatic taxa, spores and algae. The XRF core scanning was performed with an AVAATECH (GEN-4) scanner at 5 mm resolution using a 10 kV energy level without filter, a current of 200 mA, and a counting time of 10 s. The geochemical results include the Si normalised counts and the log(Ca/Fe) ratio.

title: XRF-Scanning elemental data 10kV of IODP Site 363-U1483

description: We performed high-resolution X-ray fluorescence (XRF) core scanning with the 2nd Generation Avaatech XRF Core Scanner at the Institute of Geosciences, Christian-Albrechts-University, Kiel (Germany). The archive halves were equilibrated to room temperature before scanning and a thin layer of sediment was removed from the top to obtain a fresh, even surface for scanning. We scanned at 2 cm intervals along the shipboard splice with approximately 1–2 m overlaps at splice tie points. Scanning was performed with 10 kV (750 µA, 10s acquisition time, no filter) and 30 kV (2000 µA, 20s acquisition time, Pd-thick filter) on the archive halves, which were covered with a 4 µm thick Chemplex Prolene Thin-Film foil to prevent contamination of the XRF detector. We used a crosscore slit size of 1.2 cm and a downcore slit size of 1 cm. The data reported here were acquired by a XR-100CR detector from Amptek and an Oxford Instruments 50W XTF5011 X-Ray tube with rhodium (Rh) target material. Raw X-ray spectra were converted into area counts using the iterative least-square software package WIN_AXIL from Canberra Eurisys and a core-specific model. The elements Al, Si, S, K, Ca, Ti, Mn, and Fe were analyzed with the 10-kV setting and the elements Br, Rb, and Zr with the 30-kV setting. Measured area counts per second of the spectral peaks of each element were transferred to logarithmic elemental ratios, which provide the most easily interpretable signals of relative changes in chemical composition.

Here we standardized X-ray fluorescence core scanning (XRF)-based element data of sediment core 16-KP-04-L19_Long_2 retrieved in 2016 in Lake Rauchuagytgyn (Chukotka, Russia). Lake Rauchuagytgyn is situated within the Rauchua mountain valley in the north-western Anadyr Mountains of Chukotka (Arctic Siberia). It lies at an elevation of ca. 625 m a.s.l. with a surface area of ca. 6.1 km2 and maximum water depth of 36 m. The 3 m sediment core 16-KP-04-L19 was retrieved by a modified hammer UWITEC gravity corer deployed from a catamaran during the RU-Land_2016_Keperveem expedition of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI, Germany, Potsdam) in cooperation with the North Eastern Federal State University (NEFU, Russia, Yakutsk). It was collected within 3 m PVC plastic liners, cut into 1-m pieces until further analyses. Sediment cores were tranported to AWI and one half scanned for elemental data by X-ray fluorescence (XRF) analysis at the Federal Institute for Geosciences and Natural Resources (BGR), Berlin, Germany.

title: X-ray flouorescence (XRF) based Iron and Barium/Titanium record of core SO264_45-2 from the North Pacific over the past 650 ka

description: The dataset comprises X-ray fluorescence (XRF) measurements of the elements Barium, Iron and Titanium of gravity core SO264-45-2, which was recovered from Jimmu Seamount (46.5632°N 169.601211°E) from 2425 m water depth during R/V SONNE cruise SO264 (SONNE-EMPEROR) in August 2018. XRF measurements comprise the upper 3.44 m of the core thereby covering the past ~650 ka BP and were carried out on an Avaatech XRF core scanner at the Alfred‐Wegener‐Institute Bremerhaven (AWI). Each segment was scanned at a 1 cm resolution. Here the barium/titanium (Ba/Ti) record is used as proxy for changes in paleoproductivity (biogenic barium) and the iron (Fe) record as proxy for relative changes in terrigenous input.
