title: Sodium and calcium data from the full Skytrain Ice Rise ice core

description: This dataset consists of sodium (Na) and calcium (Ca) data for the full length of the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. The data were from water sampled continuously from the melt stream of a continuous flow analysis system and are presented at 20 cm resolution where data exist. The analysis method was inductively coupled mass spectrometry using an Agilent 7700x ICP-MS attached to the melt stream.
description: Na and Ca concentrations obtained from CFA melt line using ICPMS. 43Ca signal was used; ssNa was calculated using Ca/Na ratios of 0.038 for marine and 1.78 for terrestrial.

description: This dataset consists of total air content (TAC) data from the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. Measurements were made on core sections of various lengths (but typically 10 cm) using a volumetric vacuum-extraction method built in house. No cut-bubble correction has been applied to these data.

title: Water isotope data for the full Skytrain Ice Rise ice core obtained using the CFA melt stream

description: This dataset consists of water isotope data (δ18O and δD) for the entire 651 m 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. Remaining data in doi:10.1594/PANGAEA.973166 are from water sampled continuously from the melt stream of a continuous flow analysis (CFA) system (data labelled as CFA), and are presented at 20 cm resolution where data exist. Discrete samples (see doi:10.1594/PANGAEA.973167) were also taken both as a check, and in areas where the CFA data are missing; these data are suitable for calculating deuterium excess. Data were measured using a Picarro L2130-i cavity ringdown spectrometer. Note the that top 418 m have previously been archived at 10 cm resolution (as doi:10.1594/PANGAEA.966226)

title: Palaeomagnetic measurements for IODP Site 379-U1533

description: Palaeomagnetic measurements of u-channels collected from IODP Site 379-U1533 sediment cores in 2019-2020 at the University of Southampton. U-channels were measured at 1-cm intervals on a 2G Enterprises Model-755R pass-through superconducting rock magnetometer. Principal component analysis (PCA) calculations of inclination, declination and maximum angular deviation completed using UPmag software for the Natural remanent magnetisation (NRM) alternating field demagnetisation peak field range of 20 mT to 60 mT. Measurements cover the Plio-/Pleistocene period, in the aim of refining the shipboard magnetostratigraphic age model. See Hopkins et al. (2024, doi:10.1016/j.quascirev.2023.108460) for more information on data acquisition and processing.

title: Antarctic relative palaeointensity stack (ANT-1600)

description: Relative palaeointensity (RPI) stack calculated by interpolating nine published RPI records with IODP Site 379-U1533, and 90% confidence interval of resulting stack. Site IODP Site 379-U1533 RPI calculated by normalising natural remanent magnetisation (NRM) by anhysteretic remanent magnetisation (ARM) (NRM/ARM) for the alternating field (AF) demagnetisation range 20-55 mT. Each record in the stack was interpolated and normalised by their mean age increment and mean value respectively, before bootstrapping each record centred at each 1-kyr time step with a 1-ka overlapping window. RPI records used in the stack are located along the Antarctic Peninsula, the Wilkes Land Margin, and in the Ross Sea, with IODP Site 379-U1533 being the only site located in the Amundsen Sea. More details in Hopkins et al. (2024, doi:10.1016/j.quascirev.2023.108460).

title: Relative palaeointensity stack of IODP Site 379-U1533

description: Relative palaeointensity analyses for IODP Site 379-U1533, completed in 2020-2022 at the University of Southampton. Three methods shown: natural remanent magnetisation (NRM) normalised by anhysteretic remanent magnetisation (ARM) (NRM/ARM) for the alternating field (AF) demagnetisation range 20-55 mT (preferred method for IODP Site 379-U1533 and used in further interpretations); NRM (at 20 mT AF demagnetisation) normalised by magnetic susceptibility (MS) (NRM/MS); and NRM normalised by isothermal remanent magnetisation (IRM) for the alternating field (AF) demagnetisation range 20-60 mT (NRM/IRM). All three methods show strong coherent signal suggesting an NRM signal largely consisting of a geomagnetic field component. R-values shown for analyses completed using UPmag slope method (Xuan and Channell, 2009 doi:10.1029/2009GC002584). Measurements cover the Plio-/Pleistocene period. See Hopkins et al., 2024 doi:10.1016/j.quascirev.2023.108460 for more information on data acquisition and processing.

title: XRF geochemistry for Site IODP 379-U1533

description: Analysis of IODP Site 379-U1533 natural log of barium (30 kV) and rubidium (50 kV) measured on Avaatech X-ray fluorescence (XRF) core scanner at International Ocean Discovery Program (IODP), College Station, Texas in 2019. Measurements were completed on archive halves of core sections at 2-cm resolution in order to better understand the elemental composition of the sediment and to construct an age model. ln(Ba/Rb) was used as a proxy for palaeoproductivity, which south of the Antarctic Polar Front is controlled be spring/summer sea ice extent. Measurements cover the Plio-/Pleistocene period.

title: Sequential extraction of P components (SEDEX) in sediment core M157_12-17, off Namibia

description: A 5-step sequential extraction scheme modified after Ruttenberg (1992), Schenau and De Lange (2000) and Küster-Heins et al., (2010) was used for the speciation of particulate P. Approximately 125mg freeze-dried sediment sample was successively washed with 25 ml of (1) 2 M NH4Cl (pH 7; 4 h; repeat 8 to 10 times), (2) CDB (citrate-dithionite-bicarbonate) buffer solution (pH 7.5; 8 h), (3) 1M sodium acetate buffer solution (pH 4; 6 h), (4) 1 M HCl (24 h) and (5) 1 M HCl (24 h) after ignition for 3 hours at 550 °C. The extracted P components include biogenic P in fish scales, bones and teeth that are mainly composed of hydroxyapatite (PHydap) from step 1, iron-bound P (PFe) from step 2, authigenic apatite (PAuthigenic) from step 3 typically corresponding to carbonate fluorapatite, detrital P (PDetrital) from step 4 and organic P (Porg) from step 5. The sum of these fractions gives the total P content (Ptotal). The P concentration of the solutions was determined by inductively coupled plasma optical emission spectrometry (ICP-OES) with a precision of &lt; 5 %.

title: Sediment analyses of sediment core M157_41-03

description: Particulate organic carbon (POC), total particulate nitrogen (TN) and total particulate sulfur (TS) were determined by using an element analyzer (Euro EA, HEKAtech). POC was determined after acidifying the sample with 0.25N HCl to remove carbonate. POC content refers to the dry weight percent (wt %) of C (detection limit &lt;0.1 wt% and relative error of 3%). Total iron (TFe) concentrations in the solid phase was determined by ICP-OES following digestion in nitric acid, hydrofluoric acid and perchloric acid. Porosity was determined from the water loss after freeze-drying assuming a seawater density of 1.023 g cm-3 and a particle density of 2.5 g cm-3.

description: The International Bathymetric Chart of the Southern Ocean Version 2 (IBCSO v2) is a digital bathymetric model (DBM) for the area south of 50° S with special emphasis on the bathymetry of the Southern Ocean. IBCSO v2 has a resolution of 500 m × 500 m in a Polar Stereographic projection (EPSG: 9354). The total data coverage of the seafloor is 23.79% with a multibeam-only data coverage of 22.32%. The remaining 1.47% include singlebeam and other data. IBCSO v2 is the most authoritative seafloor map of the area south of 50°S.IBCSO is a regional mapping project of the General Bathymetric Chart of the Ocean (GEBCO) supported by the Nippon Foundation – GEBCO Seabed 2030 Project. GEBCO is a project under the auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) with the goal to produce the authoritative map of the world's oceans. The IBCSO Project is also an integral part of the Antarctic research community and an expert group of the Scientific Committee on Antarctic Research (SCAR).
