Seismic bathymetry data, Antarctic Peninsula, Larsen C Ice Shelf, 2016
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.

Raw data are provided and data quality can therefore be readily assessed.
Data quality will vary from shot to shot due to the nature of using a hammer
source.
