The files include full analytical details and datasets from the laboratories used for the acquisition of U-Pb zircon geochronology and Lu-Hf isotope geochemistry. The data were collected in the interval September 2022 to January 2023 across a number of laboratories: Stockholm, University College London and Australian National University (U-Pb zircon geochronology); British Geological Survey (Lu-isotopes). The analyses were conducted by Teal Riley (Stockholm, British Geological Survey), Ian Millar (Australian National University) and Andrew Carter (University College London). The analyses were conducted to examine the provenance and depositional history of the Fossil Bluff Group fore arc basin sediments of Alexander Island. NERC N-ALI funding to Geology & Geophysics.

This dataset comprises data from a series of peat cores extracted from Site KER1, Kerguelen Island. Data includes: 1 mm-scale (contiguous) spectra count per second (cps) chemical element data from composite downcore X-ray Fluorescence Core Scan (XRF-CS) geochemical data, ~1 cm-scale (interval) Inductively Coupled Mass Spectrometry (ICP-MS) geochemical and subsample data, 5 mm-scale (interval) Multi Sensor Core Logger (MSCL) data, and sedimentological parameters. The data set was used in conjunction with other peat core records from five sites on four sub-Antarctic Islands for calibration of XRF-CS to ICPMS to quantify high resolution XRF-CS to enable dust flux calculations at high resolution.

This dataset contains geochemistry measurements and fossil diatom counts made on a sediment core from La Grange Cop lake, Marion Island (46deg94S, 37deg60E, 60 m above sea level). The dataset consists of diatom relative frequencies, diatom principal components analysis (PCA), and diatom-inferred conductivity, ITRAX scanning XRF elemental percentages and XRF PCA, C%, N%, and delta13C measurements, and magnetic susceptibility measurements. Ages of the sediment samples were assigned based on an age depth model derived from 210Pb, 137Cs, and 14C measurements and span the last c. 700 years. This project was funded by UK Natural Environment Research Council Grant NE/K004514/1 to Dominic A Hodgson and a Research Foundation-Flanders travel bursary to Elie Verleyen.

This dataset presents the relative diatom abundances of 56 species/groups from the 132-120 ka interval in marine sediment core ANTA91-8 (-70.78 degN, 172.83 degE). This age interval corresponds to the peak of Marine Isotope Stage 5e. Microscope slides were prepared using a method adapted from Scherer (1994) and 300+ diatom valves were counted for each depth sample to produce the relative percentage abundance of each diatom species/group. The age model for this dataset has been updated, with new tiepoints between the sediment core magnetic susceptibility and the LR04 benthic delta-O-18 stack selected to improve the graphical alignment. This project was funded by the UK Natural Environment Research Council Grant NE/L002531/1.
