Magnitude and x and y components of surface speed on the Larsen C ice shelf, Antarctica. The datasets are annual means from 2015 to 2022 at a horizontal resolution of 100 m. The data are based on feature tracking of Sentinel 1 Synthetic Aperture Radar (SAR) satellite data. The velocities were created to support a NERC-funded project investigating ice-shelf rift propagation, by Prof. Adrian Luckman. NERC standard grant NE/T008016/1.

Polarimetric phase-sensitive radar measurements were collected at the Western Antarctic Ice Sheet (WAIS) Divide on the 25th and 26th December 2019. The measurements were conducted at 10 sites along a 6 km-long transect ~5-10 km northeast of the location of the WAIS Divide Deep Ice Core. At each site, a suite of four quadrature (quad-) polarimetric measurements were collected using an autonomous phase-sensitive radio echo sounder (ApRES) in a single-input single-output (SISO) configuration. The study is part of the Thwaites Interdisciplinary Margin Evolution (TIME) project of the International Thwaites Glacier Collaboration (ITGC), and is a collaboration between the United States National Science Foundation (NSF) and the United Kingdom Natural Environment Research Council (NERC). It was funded by UK Natural Environment Research Council (NERC) research grant NE/S006788/1 and USA National Science Foundation (NSF) research grant 1739027.

A time series of surface ice flow speed at a point on Thwaites Glacier, West Antarctica. The point is on grounded ice and is upstream of a sub-shelf cavity on the west flank of the fast-moving core of Thwaites Glacier. There are a total of 589 points. First column = yyyy-mm-dd, second column = speed in kilometres per year. The work was funded by NERC projects NE/P011365/1 and NE/S006605/1.

This is an electric log of a borehole drilled by hot water to 120 m (Site 1) on Larsen C Ice Shelf, Antarctic Peninsula. The borehole was drilled in December 2022 to investigate the internal properties of a suture zone (Site 1) and a meteoric ice band (Site 2) of an ice shelf, as part of the NERC-funded RiPIce (Rift Propagation for Ice sheet models) research project. NERC standard grant NE/T008016/1.

The datasets are temperature time series from fibre-optic strings installed into two boreholes on Larsen C Ice Shelf, Antarctic Peninsula. Boreholes were drilled in December 2022 to 160 m to investigate the internal properties of a suture zone (Site 1) and a meteoric ice band (Site 2) of an ice shelf, as part of the NERC-funded RiPIce (Rift Propagation for Ice sheet models) research project. NERC standard grant NE/T008016/1.

The dataset contains terminus positions and flowlines of the Vincennes Bay Outlet Glaciers, for the years 1963-2022. These are provided as shapefiles, associated with a paper submitted to The Cryosphere entitled Extensive and anomalous grounding line retreat at Vanderford Glacier, Vincennes Bay, Wilkes Land, East Antarctica (Picton et al., 2023). The dataset is divided into three separate folders: (i) flowlines, (ii) sampling boxes, and (iii) terminus positions. The flowlines and sampling boxes, shown in Figure 1B (Picton et al., 2023), were used to facilitate data collection. The terminus positions represent annual terminus positions manually digitised from satellite imagery. Flowlines, sampling boxes and terminus positions are provided for each of the Vincennes Bay outlet glaciers: Vanderford, Adams, Anzac, Bond East, Bond West, and Underwood. Chris Stokes and Stewart Jamieson acknowledge funding from the UK Natural Environment Research Council grant NE/R000824/1.

Thwaites Glacier, West Antarctica. A time series of 156 profiles of ice surface elevation along a flowline based on the mean flow direction. The flowline passes through a region of large elevation change that took place between 2014 and 2017. The work was funded by NERC projects NE/P011365/1 and NE/S006605/1.
