title: Glacier mass balance Hallstätter Gletscher 2018/19, Dachstein, Austria

description: The annual glacier mass balance of Hallstätter Gletscher in Austria is measured since 1.10.2006 with the direct glaciological method in the fixed date system (1.10. to 30. 09. of the following year). The accumulation of snow is measured by determination of the water equivalent in 6 snow pits, the ice ablation is measured with 15 stakes drilled into the ice. Results are the annual net mass balance in kg, the total accumulation and ablation, the glacier area and the portions of the area which are subject to ablation and accumulation, the elevation of the equilibrium line and the specific mass balance in kg/m² (= mm w.e.). The accumulation during the winter is determined by the 1 May.The project is funded by the Federal Government of Upper Austria. The measurements are carried out the Institute for Interdisciplinary Mountain Research of the Austrian Academy of Sciences and the company Blue Sky in Gmunden, Austria.

title: Secondary standard for determining geochemical composition of tephra layers from deep sediment core GS16-204-22CC

description: We investigated marine sediment core GS16-204-22CC for increased tephra occurrences and geochemically analysed the major element composition of tephra shards to identify their source volcano(es). In total we observed eight tephra zones of which five concentration peaks show isochronous features that can be used as independent tie-points in future studies. To ensure analytical precision, secondary standards (BCR2g (Basalt) and Lipari Obsidian (Rhyolitic)) were measured at the start and end of each run.

title: Surface velocities for selected key regions in Greenland and Antarctica

description: Surface velocities for the onset of the North East Greenland Ice Stream (NEGIS) are based on SAR interferometry using ascending and descending satellite tracks and the assumption of surface parallel ice flow. Data for the high resolution field (30 m res) in the vicinity of the EGRIP drill site were acquired by TerraSAR-X between 2016 and 2018. TerraSAR-X raw data were made available through DLR proposal HYD2059. Another velocity field at the onset of NEGIS is a mosaic of Sentinel-1 estimates acquired in early 2019, following a similar interferometric processing scheme as for the TerraSAR-X velocity field. The third velocity mosaic covers large parts of NE Greenland and was derived by intensity offset tracking on Sentinel-1 winter acquisitions between 2016 and 2018.Surface velocities in the region of the Filchner-Ronne Ice Shelf (Antarctica) were derived from Sentinel-1 and TerraSAR-X intensity offset tracking and filled with Landsat 8 velocity estimates downloaded from the Global Land Ice Velocity Extraction from the Landsat 8 (GoLIVE) database (Scambos et al., 2016). The higher resolved velocity field of Support Force Glacier (50 m res) is only based on TerraSAR-X intensity offset tracking and GoLIVE velocity estimates. TerraSAR-X raw data were made available through DLR proposal HYD2059.

title: RECAP ice core Holocene record of δ¹⁸O

description: The RECAP ice core was drilled on the Renland Ice Cap (71° 18′18′′ N, 26° 43′24′′ W; 2315 m a.s.l.), coastal East Greenland, in 2015. This repository contains ice core values of d^18^O of the upper ca. 530 meter section of the core, corresponding to the ca. 11,000 years of the Holocene. The time series is smoothed using a 100-yr Gaussian kernel. The data are from Hughes et al., 2020: High-frequency climate variability in the Holocene from a coastal-dome ice core in east-central Greenland.

title: Line-scan grey-scale intensity profile from the NGRIP2 ice core, Greenland

description: A continuous high-resolution record of digital images was obtained from the North Greenland Ice Core Project (NGRIP) ice core in the depth interval from 1330 m to the bedrock at 3085 m during the Greenland field seasons of 2000 and 2001. The images are obtained as dark-field images from an indirect light source and provide detailed visual documentation of the ice core at high depth resolution. The visual stratigraphy grey-scale intensity profile (the line-scan profile) is obtained as an averaged intensity profile from the centre part of the stratigraphy images along the direction of the core. The dataset covers the depth interval 1371.15-2425.00 m in 1 mm depth resolution and with grey scale values in the range of 0-255. The profile is unprocessed and includes all core breaks that give rise high intensity values that should be regarded as contamination. Furthermore, the profile suffers from an intensity saturation issue that is uncorrected for. Finally, the section 1371.15–1750 m depth is hampered by ice relaxation effects as this section of the core was overwintering in Greenland for one year prior to analysis. The dataset was applied to construct the glacial part of the GICC05 ice-core chronology. The analytical technique and the intensity profile are described in Svensson et al. (2005).

title: GRIP ice core detailed water isotope (δ18O) data

description: The ice core was drilled during the GRIP project in 1989-1992 at the Summit of the Greenland ice sheet. The length is 3025 m. Present-day accumulation 0.23 m ice/yr. Position 72.57N 37.62W, 3232 m a.s.l.. Data from the top 101.3 m comes from the S3 shallow core, but the two data sets have been fully integrated on a common depth scale. The delta-18O data were all measured immediately after the drilling (1989-90). The delta-18O data uncertainty is 0.1 per mil. All samples are cut in 2.5cm depth resolution and sample depths are for the bottom of each sample. As diffusion in the firn and snow degrade the annual signal, the data are also provided in a deconvoluted version that seeks to correct for this effect. Following the approach of S.J. Johnsen, the deconvolution uses an adaptive cut-off frequency permitting a fixed maximimum amplification (50) of the spectral components in the original data.

title: NorthGRIP ice-core record of major ions measured using ion chromatography covering the last two millennia and additional short Holocene sections

description: Ion concentration data was obtained from the NGRIP1 ice core drilled in 1996 and 1997. NGRIP1 camp position 75.1N, 42.32W. All samples were cut and decontaminated using a microtome knife in a laminar-flow bench at the field site. In 1996, the 9.850 – 349.250 meter depth interval was cut continuously in 5 cm resolution. In 1997, selected sections from the Holocene, mainly containing volcanic signals, were cut in 5 cm or 2.5 cm depth resolution. Samples covering the 8.2 ka BP cold event were cut from the depth interval 1221-1237.5 m. The frozen samples were thawed in the laboratory and immediately after poured into sample vials for ion chromatography analyses. Bags 212-403 were measured in Department of Physical Geography, Stockholm University, Sweden. The rest of the samples were measured at the Geophysics Department, Niels Bohr Institute, University of Copenhagen, Denmark, on a Dionex 500 IC. The data are labeled "Sto" and "Cph" for samples analysed respectively in Stockholm and Copenhagen. Data measured in Stockholm were calibrated to a calibration curve established using eight standards, while data measured in Copenhagen were calibrated to a linear calibration curve established using a single standard. Ammonium concentrations measured in Copenhagen may be biased due to possible sample uptake of Ammonium from the air while in the liquid phase. In Stockholm, Li⁺ was not measured and F⁻ -concentrations may be biased due to methods that was not optimal for quantification of fast eluted ions. All values are ion concentrations given in µeq/L (micro-equivalent per liter melted ice). Data were collated November 2000 by Marie-Louise Siggaard-Andersen. Samples that are labeled PID (Possible Improper Decontamination) was marked in the field in cases where proper decontamination could be questioned. However, the amount of contamination is limited because the samples were in a solid state and the environment was very clean. Samples labeled PCL (Possible Contamination in the Liquid phase) was marked in the laboratory or during data evaluation in cases where contamination could be questioned. Samples labeled "remeasured" have been measured from a portion of the sample that has been kept in liquid state for several hours after thawing. The organic acids, formic acid and acetic acid, were measured but not quantified. A few sample are labeled "Organic Acid" because significant large amounts was observed in the chromatograms. The data file is released in connection with the ESSD paper of Rasmussen et al. (2023). Information about analysis setup can be found in Littot et al. (2002), Siggaard-Andersen et al. (2002), and Jonsell et al., (2007).

title: Composite Greenland atmospheric temperature record from the GISP2, NGRIP, and NEEM ice cores

description: This dataset consists in a composite Greenland atmospheric temperature record, which was built with the following records: the GISP2 atmospheric temperature record by Kobashi et al. (2017) for the 10–0 ka BP period, the NGRIP atmospheric temperature record by Kindler et al. (2014) for the 120–10 ka BP period, and the NEEM atmospheric temperature record by NEEM community members (2013) for the 129–120 ka BP period. The NEEM temperature anomalies obtained by NEEM community members (2013) were shifted by –31 °C to obtain absolute air temperatures. The employed age model is the one of Davtian and Bard (2023) for Greenland and Antarctic ice-core records.

title: Internal reflecting horizon 1 in the Dome C region of Antarctica

description: This dataset consists of radar IRHs (internal reflecting horizons) which were traced across ice-penetrating radar surveys conducted between 2016 and 2018 over the Dome C region of the East Antarctic Plateau. The dataset is associated with the publication Chung et al. (2023). The data was collected during two radar surveys conducted in the Antarctic field seasons of 2016-17 and 2017-18 using the sledge-borne DEep LOoking Radio Echo Sounder (DELORES) from the British Antarctic Survey (BAS). The surveys covered two areas around Dome C which were identified as potential drill sites for the Beyond EPICA Oldest Ice drilling project - Little Dome C (LDC) and North Patch (NP). The LDC area is covered by a dense network of 116 radar transects, mostly organised as a grid, with denser data acquisition in areas of particular interest. At NP a grid of 21 radar transects were collected, covering an area of approximately 5×5 km^2. In this radar dataset, 20 IRHs and the ice-bed interface were manually traced, using the Petrel E&P Software Platform by Schlumberger. A single file for each IRH is provided in a .txt file, tab separated format with both two-way travel time and depth. The conversion done using c = 0.1685 m/us and firn correction of 10 m. The 20 IRHs are provided at 5 m along-track resolution.
