title: Age-depth model of Baltic Sea sediment core EMB201/13-4

description: In the Baltic Sea sediments, radiocarbon dating is influenced by varying influx of old carbon and reservoir age changes, which challenges the construction of robust age models. In homogeneous sediments formed during cold periods, radiocarbon ages are too old due to resuspension of old carbon by bottom currents (Moros et al. 2020). In contrast, within laminated sediments formed during warmer climates the influence of old carbon is negligible and ages from these sediments have been used for age modelling using the global-average marine reservoir age (Moros et al. 2020), since a well-defined regional marine reservoir is lacking. This dataset provides results from Bayesian age depth modelling in OxCal (v4.4) for core EMB201/13-4 retrieved from the Western Gotland Basin in the Baltic Sea. The age model is based on published radiocarbon ages from two Western Gotland Basin sediment cores (Moros et al. 2020; Häusler et al. 2017) that were transferred onto our sediment core, (ii) tephra-derived ages from the four tephra isochrons in our core, and (iii) a regional marine reservoir age calculated from the age offset between our tephra and radiocarbon ages from the same laminated sediment intervals in core EMB201/13-4. First, our regional marine reservoir age of 250±50 years was subtracted from all radiocarbon ages and then the age model was calculated in OxCal (v4.4) using a P_Sequence (1,0.2,U(− 2,2)) and IntCal20 (Bronk Ramsey, 2008; Bronk Ramsey, 2009; Bronk Ramsey and Lee, 2013; Reimer et al., 2020). The age model spans 561.8-57 cm depth (c. 6935-347 cal. a BP).

title: Major element glass geochemistry data of cryptotephra from Baltic Sea sediment cores EMB201/13-4 and POS507/29-2 measured with an electron micro probe analyser (EMPA)

description: This dataset provides the first tephra results from Baltic Sea sediments, analyzed in sediment cores EMB201/13-4 and POS507/29-2 from the Western Gotland Basin. Using chronostratigraphic information from previous Western Gotland Basin age models, both cores were scanned selectively to target specific large Holocene volcanic eruptions in Iceland. Core EMB201/13-4 was analyzed between 220-270 cm, 316-322 cm, and 350-400 cm; core POS507/29-2 between 0-55 cm. Sampling for cryptotephra was performed first in continuous 5-cm steps and subsequently in contiguous 1-cm steps after tephra identification in the 5-cm samples. The central part of EMB201/13-4 was only sampled in continuous 1-cm steps. In total, 62 samples were investigated. The cryptotephra glass shard extraction protocol followed established separation procedures after Blockley et al. (2005). Glass shards were identified, counted and picked in water under a Keyence VHX-970F digital microscope using a Keyence VH-Z100R lens and the VHX Control System (Kearney et al. 2024), as well as using a 100 μm-diameter gas-chromatography syringe attached to a micromanipulator (Lane et al. 2014, doi:10.1016/j.jas.2013.10.033). Subsequently, the shards were embedded in Araldite 2020 epoxy resin, and ground and polished for electron probe microanalyses (EPMA). Major element composition of individual glass shards was measured using a JEOL JXA-8230 electron microprobe at GFZ Potsdam, Germany (15 kV, 10 nA, 5-10 µm beam size). Instrumental calibration used natural mineral standards and analytical runs were monitored using glass standards (see dataset "Electron micro probe analyser (EMPA) glass standard measurements associated with glass geochemistry data of cryptotephra from cores EMB201/13-4 and POS507/29-2"). Sample measurements with analytical totals below 95% were excluded, so that 132 volcanic glass shards in 21 samples remain in total. In core EMB201/13-4, four peaks in glass shards were identified as tephra horizons in the time interval 4500-2000 a BP, with isochrons within these horizons being defined as first major occurrence of glass shards. The glass measurements show mostly rhyolitic, dacitic and andesitic compositions and only minor contributions from basaltic and phonolitic glasses, clustering in five tephra populations and 32 geochemically different shards. The majority of shards is sourced from Icelandic volcanoes.

title: Electron micro probe analyser (EMPA) glass standard measurements associated with glass geochemistry data of cryptotephra from Baltic Sea sediment cores EMB201/13-4 and POS507/29-2

description: This dataset provides the data for the four glass standards used for monitoring the precision and accuracy of electron probe microanalyses (EPMA) during analytical runs of cryptotephra glass shards in sediment cores EMB201/13-4 and POS507/29-2. For each EPMA run, all four glass standards were measured. The major element composition of the glass standards was measured using a JEOL JXA-8230 electron microprobe at GFZ Potsdam, Germany (15 kV, 10 nA, 5-10 µm beam size). Instrumental calibration used natural mineral standards. Glass standards were Lipari obsidian (Hunt & Hill 1996; Kuehn et al. 2011) and MPI-Ding glasses ATHO-G, StHs-6-80-G and GOR-132-G (Jochum et al. 2006).

title: Varve thickness of lateglacial ICDP core 5017-1-A

description: This dataset provides annually resolved microfacies data from ICDP core 5017-1-A, retrieved from the deep northern Dead Sea basin in 2010/11, for the last glacial-interglacial transition (ca. 17-11.5 ka BP). Sediments of the Lisan Formation were investigated between ~101 and 88.5 m sediment depth below lake floor by continuous thin section microscopy, while additional macroscopic information is provided from core catchers, as well as from over- and underlying sediment sections. Thin sections were prepared following the standard procedure by Brauer and Casanova (2001) that was adjusted for salty sediments. Thin section analyses were performed on overlapping large-scale thin sections using a Zeiss Axiolab pol microscope at magnifications of 50-400x. Microfacies analyses included varve counting and measurements of varve and sublayer thickness.

title: Lithology and varve chronology for sediment profile Masada

description: This dataset provides microfacies data from the sediment profile at Masada (MAS), located at the southwestern shore of the Dead Sea for the last glacial-interglacial transition (ca. 17-11.5 ka BP). The uppermost ~3.8 m sediments of the Lisan Formation were analyzed, which form the terminal deposit at this site. About 1.37 m from the uppermost UGU to the lowermost AGU were sampled continuously for thin section analyses, while macroscopic information is provided for most of the gypsum units. Sampling was performed in 2018 and followed the subsequent procedure: after smoothing the outcrop surface with a sharp knife, stainless steel boxes (~34 cm x 5 cm) with removable side walls were pressed into the sediment along a vertical profile. The boxes were overlapping by several centimeters and a battery-operated dovetail saw was used to cut the hard gypsum sections. At the GFZ in Potsdam, the sediments were carefully transferred into aluminum boxes and impregnated with epoxy resin. Thin sections (10x2 cm) with 2 cm overlap were prepared subsequently. Thin section analyses were performed using a Zeiss Axiolab pol microscope at magnifications of 50-400x. A floating varve chronology was established between the UGU and AGU and anchored at the bottom of the AGU using the transferred age from the new OxCal age model from the ICDP core. Uncertainties are derived from the age model and varve counting. Microfacies analyses included varve counting and measurements of varve and sublayer thickness.

description: A total organic carbon (TOC) record covering the last 9600 years was measured from freeze-dried and homogenized samples of Lake Kälksjön (central Sweden) sediment core KKJ19 at 1 cm resolution using an EA Isolink elemental analyzer coupled to a DELTA V advantage isotope ratio mass spectrometer. Sediment core KKJ19 was retrieved from the deepest part of Lake Kälksjön in summer 2019 with a Niederreiter piston corer. TOC measurements were performed in August 2021. Main aim of the measurements was the establishment of a time-series of paleoenvironmental variability for the western Baltic region. A 2500-year low-pass filtered version of the record was subtracted from the original data. The filtered time-series indicates qualitative changes in NAO polarity.

title: Temperature reconstructions during the late Allerød to early Preboreal from sediment core GOS18 in Lake Gościąż, Poland

description: These datasets provide data for the lowest part of a new composite profile GOS18 from Lake Gościąż in central Poland. The composite profile was established using sediment cores recovered in 2015 and 2018 with an UWITEC Piston Corer at 19.6-21.5 m water depth (Bonk et al., in press). Our data covers the time interval from the onset of lacustrine sedimentation in the late Allerød to the early Preboreal. Since Lake Gościąż comprises a continuous, seasonally resolved (varved) and exceptionally well-preserved archive of the Younger Dryas (YD) climate variation, it is highly suitable for detailed investigations of lake system responses during periods of rapid climate cooling (YD onset) and warming (YD termination), respectively. Chironomidae head capsules (hc) were utilized to reconstruct the mean July air temperature from the late Allerød to the early Preboreal in Lake Gościąż (central Poland). Sample resolution ranges from 0.5 to 6 cm. Two different training sets were used for the reconstruction - the Swiss-Norwegian-Polish Training Set (SNP TS) (Kotrys et al. 2020) and the East European TS (EE TS) (Luoto et al. 2019). Both use the Weighted Averaging-Partial Least Squares transfer function (WA-PLS).The dataset incorporates the composite depth and age [BP] for the sample midpoint, as well as for both training sets, respectively, the chironomid-inferred mean July air temperature, the standard error and the squared chi-square distance between the fossil sample and its closest modern analogue in the respective training set.

All samples were freeze-dried, manually ground and homogenized, while samples for δ13Corg were additionally de-carbonized in situ. The dataset incorporates the composite depth and age [BP] for the sample midpoint, as well as the respective δ18Ocarb and δ13Corg values.

Since Lake Gościąż comprises a continuous, seasonally resolved (varved) and exceptionally well-preserved archive of the Younger Dryas (YD) climate variation, it is highly suitable for detailed investigations of lake system responses during periods of rapid climate cooling (YD onset) and warming (YD termination), respectively.Our varve chronology is the lowest part of a new floating varve chronology established for Lake Gościąż (central Poland) that has been anchored to the absolute time scale through radiocarbon dating and age modelling (Bonk et al., in press). The here presented varve chronology reaches from the onset of lacustrine sedimentation in the late Allerød until the early Preboreal. Uncertainties for the absolute ages are derived from radiocarbon age modelling and varve counting. The internal varve counting uncertainty for the observed time interval is generally low (+14/-22) due to the mostly excellent varve preservation. Microfacies analyses, including varve counting and measurements of varve and sublayer thickness, have been performed on overlapping large-scale thin sections under an Axioplan 2 and Axiolab pol imaging microscope at magnifications of 50-400x. Thin sections have been prepared from 10 cm long freeze-dried and resin impregnated sediment slices (Brauer & Casanova 2001; doi:10.1023/A:1008136029735). The dataset incorporates the composite depth, age [BP] and age uncertainties [BP] for the varve bottom, the total varve thickness, selected sublayer thicknesses, detrital sublayer occurrence, the different varve types and the varve quality index (VQI).

title: Pollen record of core GOS18 from Lake Gościąż

description: To revise the chronology for the Lake Gościąż record, sediment cores were retrieved during two field campaigns in 2015 and 2018. Four overlapping sections were collected using a UWITEC Piston Corer (Ø 90 mm) in the deepest part of Lake Gościąż, Poland (52.583022 N, 19.339946 E). The chronology was obtained by triple varve counting on petrographic thin sections that was complemented by 137Cs measurements and 14C AMS dating of terrestrial plant remains. Additionally, part of the chronology between 520-758 cm was obtained through age-depth modelling. Pollen analysis was performed for seventy one samples, prepared according to standard procedure, and analyzed in three intervals: i) from 1859.9 cm to 1874.4 cm with 2 cm resolution, ii) from 1880.2 cm to 1896.7 cm with 1-2 cm resolution and iii) from 1741.4 cm to 1798.4 cm with 0.5-3 cm resolution. The record is mostly varved and the bottom of the composite profile coincides with the onset of lacustrine sedimentation in the late Allerød at 12,834 +134/-233 varve yrs BP.

title: A numerical discrete element study on the influence of an embedded viscoelastic–plastic layer at different viscosity values

description: The major aim of this study was to examine the influence of an embedded viscoelastic-plastic layer at different viscosity values on accretionary wedges at subduction zones. To quantify the effects of the layer viscosity, we analysed the wedge geometry, accretion mode, thrust systems and mass transport pattern. Therefore, we developed a numerical 2D 'sandbox' model utilising the Discrete Element Method. Starting with a simple pure Mohr Coulomb sequence, we added an embedded viscoelastic-plastic layer within the brittle, undeformed 'sediment' package. This layer followed Burger's rheology, which simulates the creep behaviour of natural rocks, such as evaporites. This layer got thrusted and folded during the subduction process. The testing of different bulk viscosity values, from 1 × 10**13 to 1 × 10**14 (Pa s), revealed a certain range where an active detachment evolved within the viscoelastic-plastic layer that decoupled the over- and the underlying brittle strata. This mid-level detachment caused the evolution of a frontally accreted wedge above it and a long underthrusted and subsequently basally accreted sequence beneath it. Both sequences were characterised by specific mass transport patterns depending on the used viscosity value. With decreasing bulk viscosities, thrust systems above this weak mid-level detachment became increasingly symmetrical and the particle uplift was reduced, as would be expected for a salt controlled forearc in nature. Simultaneously, antiformal stacking was favoured over hinterland dipping in the lower brittle layer and overturning of the uplifted material increased. Hence, we validated that the viscosity of an embedded detachment strongly influences the whole wedge mechanics, both the respective lower slope and the upper slope duplex, shown by e.g. the mass transport pattern.
