Rock samples were collected from the northern LeMay Range, southern Douglas Range and the Lully Foothills of Alexander Island during the 2004-2005 field season, and transferred to the Open University (OU) via the British Antarctic Survey. Samples were stored in the OU rock store during preparation for isotopic work.

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.

Key geological boundaries were identified and mapped onto aerial photos and satellite images.

This record consists of 5 different datasets covering the Alexander Island region of Antarctica: coastline (including grounding line and ice shelf fronts), contours, spot heights, rock outcrop and lakes. The data have been produced for a new topographic map of Alexander Island at 1:500,000 scale, produced by the Mapping and Geographic Information Centre, British Antarctic Survey. The data are suitable for a 1:500,000 scale map but may be suitable for larger scales in certain areas. They have been created from source data ranging from 2022 - 2025. The data primarily cover Alexander Island, and also cover Rothschild, Charcot and Latady islands, as well as Wilkins and George VI ice shelves, and the Rymill Coast section of Palmer Land on the Antarctic Peninsula. The datasets were created using a mixture of GIS software, primarily digitised from Sentinel-2 satellite imagery or extracted from high resolution, published elevation models. Exact details of each dataset can be found in the lineage statements.
