  • This archive is a suite of ground penetrating radar (GPR) data acquired by Project MIDAS during field campaigns on Larsen C, in 2014 and 2015. All data were acquired with a Sensors&Software pulsEKKO PRO GPR system, fitted with antennas of 200 MHz centre-frequency. The system was towed behind a snowmobile, with distances recorded with GPS. These data are part of the NERC-funded MIDAS (''Impact of surface melt and ponding on ice shelf dynamics and stability'') research project, with grant references NE/L006707/1 and NE/L005409/1. Other MIDAS data are available.

  • A geographic database of lakes on the Antarctic Peninsula compiled over the past five years from a number of information sources: satellite images, aerial photography, old maps and reports. The database fields include: Lake unique id; Name; location; imager reference/how identified; locality; size (longest axis); area; type (as per Hutchinson''s lake classification); reference - any existing scientific work on the lake; salinity; depth; x co-ordinate; y co-ordinate. Many of the lakes are previously unknown, and very few have been studied before. The list represents the first attempt to collate all the lakes in the area into one usable dataset. The data is available as a down-loadable text file with point co-ordinates, or as a polygon coverage downloadable from the Antarctic Digital database.

  • Aeromagnetic datasets are available for surveys over two parts of Adelaide Island- Fuchs ice piedmont at the northern end of the island and a high resolution survey grid to the south (HRAM). Data were acquired using scintrex cesium magnetometers mounted on the BAS aerogeophysical equipped Twin Otter in 2011. Data are provided as XYZ ASCII line data. This study is an output of the British Antarctic Survey (BAS) Natural Environment Research Council (NERC) Core Programme.

  • Three datasets of melt season duration in days covering the Antarctic Peninsula for the austral yeas of 2017/2018, 2018/2019 and 2019/2020. The datasets are based on ASCAT GDS Level 1 Sigma0 Swath Grid data from the EUMETSAT archive (archive.eumetsat.int/usc/) and extend an earlier time series based on enhanced QuikSCAT and ASCAT data (doi:10.5285/e3616d28-759e-4cca-8fae-fe398f9552ba). The data are supplied as GeoTIFFs. Funding was provided from the NERC grant NE/L005409/1.

  • Walk-away seismic reflection surveys were conducted in two locations on and to the south of (i.e. on the Solberg Inlet derived meteoric ice shelf unit) the suture zone emanating from the Joerg Peninsula on the Larsen C Ice Shelf, approximately 95 km downflow of the peninsula''s tip. The data were collected as part of NERC Project SOLIS. Funding was provided by NERC Standard Grant ''Present and future stability of Larsen C Ice Shelf'', 2008-2011, NERC Reference NE/E012914/1.

  • Seismic refraction experiments were conducted in four locations in the Whirlwind Inlet, Larsen C Ice Shelf, with the main purpose of estimating firn density profiles. The data were collected as part of NERC Project MIDAS. The locations, procedures and raw data files produced along with quality descriptions are all summarised in the observer''s log provided along with the datasets. Funding was provided by NERC Standard Grant ''Impact of surface melt and ponding on ice shelf dynamics and stability'', 2014-2017, NERC Reference NE/L005409/1.

  • Seismic refraction experiments were conducted in eight locations along a flowline originating in the Cabinet Inlet, Larsen C Ice Shelf, with the main purpose of estimating firn density profiles. The data were collected as part of NERC Project MIDAS. Funding was provided by NERC Standard Grant ''Impact of surface melt and ponding on ice shelf dynamics and stability'', 2014-2017, NERC Reference NE/L005409/1.

  • In 2016, a series of ice shelf cavity bathymetry point measurements were made across Larsen C Ice Shelf, West Antarctica. The sites were selected to address deficiencies in the coverage provided by existing data sets. A hammer and plate seismic source was used. Seismic reflection data were recorded on 24 receivers at 10 m interval and 30 m offset. Sea bed reflections are observed at all sites. Surface elevation measurements are provided to allow estimation of ice thickness when an ice base reflection is not visible. Funded as part of the Polar Science for Planet Earth Programme, British Antarctic Survey, Natural Environment Research Council.

  • These files comprise lists of neogastropod species from the Early Cenozoic of Seymour Island, Antarctica and tropical counterparts in both the US Gulf Coast and Paris Basin. They comprise a key part of the raw data analysed in the paper Crame et al. (2018). For each of these three localities species are listed in taxonomic order, following conventional taxonomic notation. Faunas are listed for the Paleocene, Early Eocene and Middle Eocene time intervals for the two tropical localities, but only for the Paleocene and Middle Eocene of Antarctica. The accurate location of all the localities is given in a series of published papers. The Seymour Island samples were collected across three field seasons; 1999, 2006 and 2010. The US Gulf Coast and Paris Basin data were constructed from existing literature. Funding was provided by the NERC grants NE/I005803/1 and NE/C506399/1.

  • Surface melt onset, duration and end date for the Antarctic Peninsula from 1999/2000 to 2016/2017 at a spatial resolution of 2 km, derived from scatterometer data. Years 1999/2000 to 2008/09 are based on QSCAT data and 2009/10 to 2016/17 on ASCAT data.
