title: Age model and stable oxygen isotope analyses of sediment core GeoB8507-3

description: The present study is the first study on the stable oxygen isotope composition of the photosynthetic calcareous-walled dinoflagellate species Thoracosphaera heimii off NW Africa during the last 45,000 yr. T. heimii based temperature estimates of sediment core GeoB 8507-3 were compared with those obtained from the stable oxygen isotopes of the planktic foraminifera Globigerina bulloides and Globigerinoides ruber (pink), and the Mg/Ca ratio of G. ruber (pink).We show that the isotopic composition of T. heimii and the temperature estimates based on the equation for inorganically precipitated calcite provide comparable results to those obtained from G. ruber (pink) isotopes and Mg/Ca ratios with exception of the Early Holocene and the Younger Dryas. The recently proposed palaeotemperature equation of Zonneveld et al. (2007), however, provides unrealistic temperature reconstructions that are about 16 °C lower than those based on planktic foraminifera. Thus, this equation needs to be revised. The difference between T. heimii and G. bulloides isotopic and temperature reconstructions can be ascribed to differences in the ecology of both species, especially with regard to their depth habitat and/or seasonal production in the research area.All temperature proxies suggest comparable conditions during the last glacial and Holocene. Small differences between the reconstructed temperature values of T. heimii and the other proxies can be explained by differences in seasonal production of the individual species. The relatively low temperatures recorded by T. heimii at about 15,000 to 8,000 yr BP are interpreted to reflect an increase in duration and/or intensity of the upwelling in the vicinity of the core site in comparison to the last glacial, with an abrupt and strong decrease of upwelling intensity and/or duration during the Early Holocene and the Younger Dryas.

title: Water isotope data for last 10 ka from Skytrain Ice Rise ice core

description: This dataset consists of water isotope data (δ¹⁸O and δD) for the top 418 m (back to 10 kyr before present) from the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. The top 2.83 m are from a snowpit. Most remaining data were from water sampled continuously from the melt stream of a continuous flow analysis system (data labelled as CFA), and are presented at 10 cm resolution where data exist. Discrete samples were also taken as a check, and in areas where the CFA data are missing; these data are labelled discrete. Data were measured using a Picarro L2130-i cavity ringdown spectrometer.

title: δ18O values in samples from ice wedges near the village of the Baydarata Bay

description: The main purpose of this work is to establish the formation time of Holocene syngenetic ice wedges that have been exposed on the coast of Baydarata Bay near the village of Yarynskaya, 500 m to the southeast from the mouth of the Ngarka-Tambyakha River.Radiocarbon dating of microinclusions of organic matter, extracted directly from three Holocene syngenetic ice wedges, was conducted using accelerator mass spectrometry (AMS). The dating of the wedges correlates to their formation approximately 6.4, 5.0, and 1.9 cal ka BP. A comparison of the oxygen isotopic composition of the Holocene ice wedges (in which the δ18О values vary mainly from -21.8 to -13.73%) and modern ice wedges (the age of which, as a rule, does not exceed 100 years) showed a close range of variations in values. According to isotope oxygen data, the average January air paleotemperature in the Middle and Late Holocene at the coast of the Baydarata Bay was calculated. It is shown that the average January air temperature during this period here varied from about -20 to -25 °C, however, during milder winters it could be about -18 °C. Ice samples were collected from ice wedges along the vertical profile every 10 cm using Makita DDF481rte 18B and Bosch GSR 36 VE-2-LI drills with steel ice crowns with a diameter of 51 mm. Measurements of the oxygen isotopic compositions in ice were performed on a Picarro L 2130-i laser infrared spectrometer at the Center for X-ray Diffraction Studies at the Research Park of St. Petersburg State University (XRD Center SPbU). The following international standards were used: V-SMOW-2, GISP, SLAP, USGS-45, and USGS-46. The measurement errors were ±0.02‰ for δ18O. In total,63 samples of ice wedges were analyzed.

title: Airborne sea ice parameters during aircraft flight P5_205_PAMARCMIP_2017_1704061801, Version 2

description: Airborne multi-instrument measurements of sea ice were made in April 2017 as part of the Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP) under the AWI IceBird campaign series. The data consist of four surveys spanning sea-ice covered areas in the Beaufort and Chukchi Seas. For each flight, the geolocated total (ice+snow) thickness data from an airborne electromagnetic (EM) induction sensor are provided with a point spacing of approximately 5-6 meters. Larger gaps in the trajectories arise from high-altitude calibrations of the EM sensor. The data are combined with collocated and simultaneous snow depth measurements from an airborne frequency-modulated continuous-wave ultrawideband radar, snow freeboard measurements from an airborne near-infrared laser scanner, and surface temperature measurements from an airborne infrared radiation pyrometer. Each value represents the average within the approximately 40 m diameter footprint of the EM sensor, thus representing a smoothed representation. These values are then used to derive further sea ice parameters such as sea ice bulk density. The trajectory data contain the full and unfiltered data record with quality flags.

title: Seasonal water isotope values in northeastern German lakes and ponds of the years 2020, 2022 and 2023

description: Water isotopes (δ²H and δ¹⁸O) were analyzed in samples from a range of relatively small lakes and ponds in northeastern Germany. The sampled water bodies are not connected to major river systems but are either fed by groundwater or small creeks. Water chemical parameters were determined in-situ with a portable WTW-multiparameter probe. Water samples were collected in different seasons of the years 2020, 2022 and 2023. Here, composite samples were taken from the lake centers with a Ruttner Water Sampler in 2 m intervals from the lake surface to bottom. In some cases, only a surface sample was collected from 50 cm depth using a pipette. Samples were filtered and transferred into a measurement vial. Stable isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Measurement uncertainty was quantified to &lt;0.5 ‰ for δ²H and &lt;0.2 ‰ for δ¹⁸O. The data give information about the seasonal and spatial stable isotope variability at the sampled lacustrine systems.

description: Water isotopes (δ²H and δ¹⁸O) were analyzed in samples from lakes and rivers in eastern Germany. This sub-dataset is derived from water samples collected from lake and river shores. Seasonal samples were collected in March, July, October 2022, and in March 2023, with a plastic syringe from 20-50 cm depth below water surface and directly filtered and transferred into a measurement vial. Stable isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Measurement uncertainty was quantified to &lt;0.5 ‰ for δ²H and &lt;0.2 ‰ for δ¹⁸O. Water chemical parameters were determined in-situ with a portable WTW-multiparameter probe. The data give information about the seasonal isotope amplitude at the sampled spots and about spatial isotope variability in different branches of the associated river systems.
