An airborne radar survey was flown as part of the BBAS science programme funded by the British Antarctic Survey over the Pine Island Glacier system during the austral summer of 2004/05. This survey was a collaborative US/UK field campaign which undertook a systematic geophysical survey of the entire Amundsen Sea embayment using comparable airborne survey systems mounted in Twin Otter aircraft. Operating from a temporary field camp (PNE, S 77deg34' W 095deg56'), we collected ~35,000 km of airborne survey data. Our aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, gravity meter, and the first version of a new ice-sounding radar system (PASIN) used for the first time to support this survey. We present here the full radar dataset consisting of the deep-sounding chirp and shallow-sounding pulse-acquired data in their processed form, as well as the navigational information of each trace, the surface and bed elevation picks, ice thickness, and calculated absolute surface and bed elevations. This dataset comes primarily in the form of NetCDF and georeferenced SEGY files. To interactively engage with this newly-published dataset, we also created segmented quicklook PDF files of the radar data.

This dataset contains data from three ground-penetrating radar surveys undertaken to image ice thickness and englacial stratigraphy during the 2019-20 Antarctic field season, as part of the International Thwaites Glacier Collaboration (funded by NERC and NSF). The ground-penetrating radar data are presented as SEG-Y, along with the GPS tracks of the surveys, presented as GPS Exchange Format (GPX). The subglacial extensions of ridges of three nunataks close to Pine Island and Larter Glaciers in the Hudson Mountains region were surveyed, with the aim of determining their suitability as subglacial bedrock drill sites. Those nunataks are Winkie Nunatak (74 degrees 51' 41.0" S/99 degrees 46' 49.4" W), Evans Knoll (74 degrees 51' 00.0" S/100 degrees 25' 00.0" W), and Webber Nunatak (74 degrees 47' 00.0" S/99 degrees 50' 00.0" W). This work was funded by NERC grants NE/S00663X/1 and NE/S006710/1.

This gridded dataset provides geometry (ice thickness and bedrock topography) covering the Pine Island Glacier catchment. It has been created using the principle of mass conservation, given observed fields of velocity, surface elevation change and surface mass balance, together with sparse ice thickness data measured along airborne radar flight-lines. Previous ice flow modelling studies show that gridded geometry products that use traditional interpolation techniques (e.g. Bedmap2) can result in a spurious thickening tendency near the grounding line of Pine Island Glacier. Removing the cause of this thickening signal, in order to more accurately model ice flow dynamics, has been the motivation for creating a new geometry that is consistent with the conservation of mass. This data was funded by a PhD project within the iSTAR-C programme (with NERC grant reference NE/J005738/1).

This dataset contains the position and depth of four spatially-extensive Internal Reflecting Horizons (or IRHs) traced on the British Antarctic Survey's PASIN system and NASA Operation IceBridge's MCoRDS2 system across the Pine Island Glacier catchment. Using the WAIS Divide ice-core chronology and a 1-D steady-state model, we assign ages to our four IRHs: (R1) 2.31-2.92 ka, (R2) 4.72 +/- 0.28 ka, (R3) 6.94 +/- 0.31 ka, and (R4) 16.50 +/- 0.79 ka. This project was funded by the UK Natural Environment Research Council Grant NE/L002558/1

This dataset consists of measurements of cosmogenic 10Be in quartz from a set of erratic cobbles collected from the surfaces of nunataks in West Antarctica. The cobbles were collected during the 2019-20 Antarctic field season from the Hudson Mountains, which are situated adjacent to Pine Island Glacier. The dataset includes cosmogenic nuclide (10Be) exposure ages and all field (sample locations and elevations) and analytical laboratory (quartz and beryllium carrier masses, Be-10/Be-9 ratios) data for field samples and procedural blanks required to calculate the ages.

This dataset consists of measurements of cosmogenic 10Be in quartz from a set of 41 erratic cobbles and boulders collected from the surfaces of nunataks in West Antarctica. The erratics were collected during the 2019-20 Antarctic field season from the Hudson Mountains, which are situated immediately to the north of Pine Island Glacier. The samples in this dataset were collected from nunataks (Webber Nunatak, Mount Moses, Slusher Nunatak, Dean Nunataks, Wold Nunatak, and Siren Rock) located adjacent to Larter and Lucchitta glaciers which dissect the area. The dataset includes cosmogenic nuclide (10Be) exposure ages and all field (sample locations and elevations) and analytical laboratory (quartz and beryllium carrier masses, 10Be/9Be ratios) data for field samples and procedural blanks required to calculate the exposure ages.
