Seismic refraction data from two sites on Antarctica's Larsen C Ice Shelf, Nov 2017, following the calving of Iceberg A68
GB/NERC/BAS/PDC/01226

Summary

Abstract:
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.
