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.
Seismic refraction data were acquired at two sites on Antarctica''s Larsen C Ice Shelf, in November 2017. The acquisition was performed to measure seismic anisotropy, a proxy for the stress condition, in the ice shelf following the calving of Iceberg A68 in July 2017. 2D seismic profiles were acquired at two sites: S1, close to the new calving front of the ice shelf, and S2, advected downstream from the site surveyed in the NERC funded project NE/E013414/1 (SOLIS). Profiles were rotated about a common midpoint to examine the variation in seismic properties with azimuth. Throughout, 24 geophones were deployed at 10 m offset, with data recorded at a Geometrics GEODE system; data are presented here in SEG-2 format. All acquisitions were performed by Dr Jim White (British Geological Survey) and Emma Pearce (University of Leeds, School of Earth and Environment), with support from BAS. The data is part of the NERC RACE project, NE/R012334/1.
