This dataset provides a map of the Antarctic grounding zone. The map is assembled using CryoSat-2 satellite radar altimetry data spanning between 2010-2017. This dataset provides both the limit of tidal flexure (point F) and hydrostatic equilibrium (point H) of the grounding zone. Funding was provided by the NERC grant NE/N011511/1.

This dataset contains measurements of snow accumulation over an 11-month period in 2016 at six sites in the Pine Island-Thwaites Glacier catchment of West Antarctica. The sites were visited on two occasions, the first in January 2016 and the second in December 2016. The accumulation rate at each site was calculated using an average density profile, based on a compilation of six low elevation sites on Pine Island Glacier (iSTAR sites 15-19, and 22; Morris et al., 2017) that are situated nearby. The average density for the top metre based on this compilation is 419 kg m-3. Further details are provided in the associated publication.

The first edition of the Antarctic Digital Database (ADD) coastline polyline dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Line dataset was originally published on CD-ROM in 1993, in tiled Coverage format. Data has since been converted merged to a single dataset and exported to shapefile and geopackage formats. Scale0 is the highest resolution that was produced. The ADD project was first proposed in 1990 by a Cambridge (UK) based consortium comprising British Antarctic Survey (BAS), Scott Polar Research Institute (SPRI) and the World Conservation Monitoring Centre (now UNEP World Conservation Monitoring Centre (UNEP-WCMC)). International participation in the project was agreed through the Scientific Committee on Antarctic Research (SCAR) and its Working Group on Geodesy and Geographic Information. The majority of data capture data management was undertaken in Cambridge, UK. Work was initially funded by BAS and by The British Petroleum Company p.l.c (BP). Other contributing nations sponsored their own data capture through either their national mapping agencies or their Antarctic research organisations. BP had no commercial interest in the project and the information gained from this database was in the public domain. BAS, SPRI, WCMC and SCAR, by entering into this project with BP, in no way implied their acceptance or endorsement of any exploration activity for oil, gas or minerals in Antarctica.

The second edition of the Antarctic Digital Database (ADD) coastline polygon dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Polygon dataset was originally published on CD-ROM in 1998, in tiled Coverage format. Data has since been converted and merged to a single dataset and exported to shapefile and geopackage formats. Scale0 is the highest resolution that was produced. Each polygon has a surface attribute (CST00SRF) indicating the type of feature it represents, ie. ice shelf, ice tongue, land, ocean and rumple. For information on the source of polygon delineations, refer to coincident features in the polyline dataset, Scale0 vector polylines of the Antarctic coastline v2.0. ADD Version 2.0 contained many amendments to the original data. Most corrections were made in Quadrant 4, which covers the Antarctic Peninsula, parts of Ellsworth Land and Coats Land. A few features, such as Doake Ice Rumples, were inadvertently omitted from ADD Version 1.0, so were included in this version for the first time. Data for the Ronne and Filchner ice shelves were also upgraded. A new map of James Ross Island was incorporated, and the positions of ice fronts of the northern Larsen Ice Shelf, Wordie Ice Shelf and Wilkins Ice Shelf were also amended using the latest available information. Other minor changes were also made and documented in the ADD Manual: https://nora.nerc.ac.uk/id/eprint/536533/. The UK Consortium behind the ADD Version 1.0 passed the ongoing maintenance and revision of the ADD to British Antarctic Survey (BAS) for Version 2.0.

High resolution (Scale0) polyline dataset of the Antarctic Coastline. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Line dataset was originally published in tiled Coverage format. Data has since been converted and merged to a single dataset and exported to shapefile and geopackage formats.
