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.

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. asNeeded completed
