This dataset comprises U-Pb zircon geochronology data from six rock samples from the sub-Antarctic Island of South Georgia. The data were collected in the interval November 2023 to March 2024 at the University College London. The U-Pb analyses were conducted on six granitoid samples from across South Georgia to examine the age of magmatism and how they correlate with magmatism from the northern Antarctic Peninsula and southern South America. This project was funded by NERC National Capability funding to the British Antarctic Survey's Paleo Environments, Ice Sheets and Climate Change team.

This dataset comprises U-Pb zircon geochronology and Lu-Hf isotope geochemistry on a suite of rock samples from the Drygalski Fjord region of south eastern South Georgia. Six samples were analysed: all sandstone lithologies that were examined to understand their geological provenance and how they compare to similar units from southern South America. The data were collected in the interval November 2023 to March 2024 across a number of laboratories: Stockholm Museum of Natural History and University College London (U-Pb zircon geochronology); British Geological Survey (Lu-Hf isotopes). The analyses were conducted by Ian Millar (British Geological Survey) Teal Riley (Stockholm) and Andrew Carter (University College London). The analyses were conducted to examine the provenance and depositional history of the sedimentary successions of South Georgia. This project was funded by NERC National Capability funding to the British Antarctic Survey's Paleo Environments, Ice Sheets and Climate Change team.

The cosmogenic nuclide dataset contains 15 x 10Be, 11 x 26Al and 14 x 21Ne cosmogenic nuclide concentrations for 9 bedrock and 6 boulder samples. Samples were collected by Rebecca Rixon in the austral summer of 2008/9 on the Wilkins Coast along a transect from Mount Faith in the Eternity Range via Mount Sullivan to Engels Peaks. Sample coordinates and elevations are provided in the data set, as are sample type and lithology. This work was funded under NERC Cosmogenic Isotope Analysis Allocation Nos. 9067.0409 and 9100.1010

Dataset is comprised of stable isotopes (oxygen and carbon) of benthic foraminifera from sediments from International Ocean Discovery Program (IODP) Expedition 382, Site U1534, South Falkland Sediment Drift. 53.18967 S, 58.76083 W (605 m water depth). The sediment cores were collected from 3 holes using the advanced piston corer onboard RV Joides Resolution from site U1534 between 29/03/2019 and 02/04/2019. Suitable specimens of benthic foraminifera were identified and picked from the >250 micron size fraction sediment at BAS between March 2020 and May 2021. Isotope analysis was carried out between March-August 2021. The data were collected as part of a project aiming to investigate the sensitivity of the Atlantic Meridional Overturning Circulation to variability in Pacific-Atlantic connectivity via the 'cold water route'. Dr Victoria Louise Peck was the principle investigator for this project. Funding provided by NERC UKIODP moratorium grant NE/T010908/1 and analytical support from NEIF steering committee application IP-1950-119.

Datasets related to istopic dating of mylonites and detrital grains from central Alexander Island. Argon-argon dating of mylonites and detrital grains, as well as uranium-lead dating of detrital zircons has been completed. Rock samples were collected from the northern LeMay Range, southern Douglas Range and the Lully Foothills.

Geological analyses were conducted on rock samples collected in Dronning-Maud Land during the 2007-2008 field season. Analyses included grain-size determination, dating, whole rock and inclusion mineralogy, and geochemical analyses. All of the samples taken were of rocks that were found cropping out as nunataks. The investigation took place entirely within the the Dronning-Maud Land area of East Antarctica (Norwegian Sector).

Geological station and sample registers related to rock samples collected from eastern Ellsworth Land during the 2002-2003 field season. In addition, processed data related to zircon mineral analysis using a technique that combines measurement of the U-Pb and Lu-Hf isotope systems. Minerals found in sediments that are resistant to earth surface processes, such as weathering and erosion, can yield information including the age and geological evolution of the sediment source region. Such a fingerprint is often unique and can be put in geographical context allowing an evaluation as to whether rock units today found adjacent to each other were originally deposited close to each other or not. Ultimately through rigorous zircon provenance analysis a new model for the crustal makeup of the Antarctic Peninsula can be tested.

A new technique that coupled SHRIMP (Sensitive High Resolution Ion Microprobe) U-Pb analyses with Laser ablation ICP isotope analyses for detrital zircons enabled the provenance of sediments from the English Coast region to be better assessed than had been previously possible. Such analyses, combined with Sm-Nd, Sr and Pb analyses for the sediments and plutonic rocks that cut the sediments, enabled a better assessment of the affinity of the English Coast rocks.

Geochemical analysis of rock samples acquired by dredging activities in the Scotia Sea between Feb and Mar 2004 aboard James Clark Ross (cruise no JR77). The initial aim of this project was to carry out a higher resolution geochemical study of mantle flow using existing samples. This confirmed flow from the Bouvet domain into the East Scotia Sea and placed constraints on flow pathways. The second stage was to sample further within the West Scotia Sea and to use elemental and isotope (Sr, Nd, Pb, Hf) analyses to fingerprint mantle provenance. The results were used to locate and investigate the nature of the Pacific-South Atlantic mantle domain boundary and thus to contribute to the understanding and quantification of global upper mantle fluxes.

This dataset consists of measurements of cosmogenic 14C in quartz for cobbles collected from a series of nunataks (Turtle Rock, Notebook Cliffs, scoria cone) proximal to Mount Murphy, a volcanic edifice located between Pope and Thwaites glaciers, West Antarctica. The cobbles were collected during the 2015-2016 Antarctic field season. The dataset includes 13 cosmogenic nuclide surface exposure ages and all field (location, elevation, shielding, thickness) and analytical laboratory data required to calculate in situ 14C exposure ages. Analytical data includes quartz sample mass, total CO2 liberated from the sample, delta-13C, 14C/12C AMS ratios and 14C/12C AMS ratios of procedural blanks.

The dataset is a component of the "Geological History Constraints" project of the NERC-NSF funded International Thwaites Glacier Collaboration (ITGC).
