  • 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.

  • Daily outputs on a 7.5 km horizontal resolution grid covering the Greenland Ice Sheet from MARv3.6.2, which is a regional climate model developed for the Polar regions that solves the regional climate and ice sheet surface mass balance. MAR was forced by ERA-Interim re-analysis data.

  • 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.

  • 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.

  • This data set contains aeromagnetic data collected opportunistically during an airborne radar survey of the Brunt Ice Shelf as part of the NERC/BAS Life Time of Halley project. The survey was flown draped with an average height above the ice surface of 420m, and includes 4716 km of new data. The aircraft used was the BAS aerogeophysically equipped twin otter VP-FBL. Data are available include all data streams from raw to fully processed, following the ADMAP 2 naming convention, and are provided in both Geosoft database (.gdb) and ASCII file formats (.xyz). Base station data is also provided.

  • 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.

  • The datasets are temperature time series from strings of thermistors, each located at a discrete depth within one of six boreholes drilled to a depth of ~100 m in the northern sector of Larsen C Ice Shelf, Antarctica. Supporting borehole information is presented by Ashmore and others (2017). 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. Associated (near-surface) borehole temperature records, OPTV logs and density records are also available, as are other MIDAS datasets.

  • The datasets are temperature time series from thermistor strings installed into two boreholes drilled to a depth of ~7 m in the northern sector of Larsen C Ice Shelf, Antarctica. Supporting borehole information is presented by Ashmore and others (2017). 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. Associated (longer) borehole temperature records, OPTV logs and density records are also available, as are other MIDAS datasets.
