The datasets refer to the dating of three basaltic samples collected from Bruce Bank and Jane Bank in the southern Scotia Sea. The samples were dredged from depths between 850 -1900 m from steep scrap slopes at two locations (DR.225: 59.927 degrees S, 39.154 degrees W; DR.84: 62.468 degrees S, 039.785 degrees W). The files include full analytical datasets for 40Ar/39Ar analysis of whole rock and plagioclase mineral separates performed at the Open University, UK in June 2022. This project was funded by NERC NC-ALI funding to Geology & Geophysics.

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.

Cosmogenic isotope exposure-age dating (Aluminium-26, Beryllium-10 and Chlorine-36) of granite erratic boulders and locally derived glacially transported basalt boulders from ice-free land on James Ross Island, northeastern Antarctic Peninsula. These data are used to define the evolution of Last Glacial Maximum (LGM) ice in the adjacent Prince Gustav region and the timing and duration of deglacial ice-streaming events.

A geodatabase of 186 published Quaternary marine and terrestrial dates relating to the Last Glacial Maximum (LGM) glaciation and ice retreat, which capture the dynamics and retreat of the Antarctic Peninsula Ice Sheet (APIS).
