Shapefile map of exposed rock outcrops for the Antarctic continent. The map was produced via a new fully automated methodology for differentiating rock from snow, clouds and sea using Landsat 8 multispectral imagery. Data was merged with the existing Antarctic Digital Database rock outcrop dataset for areas for those areas where Landsat 8 tiles were unavailable (south of 82 deg 40 S).

This dataset consists of spectral reflectance measurements in the visible to shortwave infrared wavelength range (0.35 - 2.5 micrometer) of 17 rock samples from Mount Murphy, a volcanic edifice in the Amundsen Sea Embayment of West Antarctica. These spectral measurements provide ground validation for satellite-based geologic mapping of the Mt Murphy edifice and surrounding nunataks. Samples measured for spectral reflectance were collected during the 1990-1991, 1992-1993 and 2015-2016 Antarctic Field Seasons. Funding source: Natural Environment Research Council (NERC) Grants NE/S006710/1, NE/S006753/1 and NE/K012088/1 and studentship to JRA. The dataset is a component of the "Geological History Constraints" project of the NERC-NSF funded International Thwaites Glacier Collaboration (ITGC).

We present a petrophysical catalogue of new density and susceptibility measurements conducted on 320 rock samples from northern Victoria Land, East Antarctica. The rock samples are stored by the Federal Institute for Geosciences and Natural Resources (BGR) in Berlin-Spandau and Hanover, Germany. Funding for this research was provided by NERC through a SENSE CDT studentship (NE/T00939X/1)

Land cover of Signy Island, consisting of rock outcrop, moraine, lakes, permanent ice and streams. All data were manually digitised from a VHR (very high resolution) satellite image acquired on the 10th February 2020. WorldView-2 satellite image (c) 2020 Maxar Technologies. The datasets are available as polygon and point shapefiles and GeoPackages. The data were created to support the updated release of the British Antarctic Survey (BAS) Signy Island map (BAS, 2024)

Despite the important tectonic and stratigraphic setting, rocks from the English Coast area remain largely unstudied, as the paucity of exposure has hindered detailed structural and sedimentological analysis. Samples were collected for zircon analysis following a traverse starting at the English Coast and ending at Sky-Blu. A total of around 250kg of rock were collected and rocks at Fitzgerald Bluffs were revisited and sampled for the first time in 25 years. Highlights included the recognition of a previously undiscovered granitoid body and the discovery of fossils that tentatively indicate that Permian rocks are more widespread in the region.

Sample inventory data related to a field campaign of approximately 10 weeks, carried out during 2007-2008. The primary focus was sample collection, with the rest of the time being used for mapping. 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).

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.

We present a 3D crustal model of density and susceptibility distribution in Marguerite Bay, west Antarctica. The inversion is based on airborne gravity and magnetic data collected with a Windracers Ultra UAV (2023/2024 Antarctic season) with a line spacing of 2 km and a ground clearness of 500m. The inverted densities and susceptibilities allow us to contain and identify large scale 3D intrusion in Marguerite Bay. We provide a CSV file, which contains the coordinates, the depth and the inverted density and susceptibility distribution. This work was funded through "Protecting environments with unmanned aerial vehicle swarms" project number 10023377 as part of "Innovate UK Future flight challenge phase 3"

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 samples collected during the 2010-11 field season from James Ross Island, northeast Antarctic Peninsula.
