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.

Methodology:
The seismic reflection data were collected using a hammer and plate source
into 24 surface receivers at 30 m offset and 10 m interval. At each site, around 20 single
blow records were collected as well as an on-site stack of 10 hammer
blows.
Seismic data were recorded at 8 kHz sample rate. The Fresnel zone is
dependent on ice and water column thickness and therefore site specific.
The dual frequency GPS data were collected with a Trimble R7 GPS unit at
each site to obtain an accurate surface elevation.
Data collection:
The seismic reflection data were collected with 1 x Geometrics Geode seismograph with 40 Hz vertical georods.
The dual frequency GPS data were collected with a Trimble R7 GPS unit.
Data quality:
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.
