Water column and ice thickness measurements of the Filchner-Ronne Ice Shelf derived from point seismic observations collected between 2015-2017
This data are derived from single point seismic data collected across the Filchner-Ronne Ice Shelf. The seismic data were collected over the course of three seasons by a number of field parties, consisting of two main surveys between the 15/16 and 16/17 austral summers and several smaller surveys, as part of a joint initiative between the British Antarctic Survey (BAS) and the Alfred-Wegener-Institute (AWI) in the framework of the "Filchner Ice Shelf System" (FISS) and the "Filchner Ice Shelf Project" (FISP). A total of 256 point seismic measurements were made, of which 248 had clearly visible reflectors and were deemed usable. Each data point consists of a location, together with measurements of ice thickness and water column thickness.
These data were collected as part of the FISS NERC large grant, project number NE/L013770/1.

Methodology:
A powered auger was used to drill shot holes of ~5m depth, which were then loaded with 150-300g of high explosives. From each shot hole, a line of 24 receivers were buried to a shallow and consistent depth to ensure good coupling with the snow and reduce wind noise. Receivers were spaced at 10m intervals, with the first receiver offset from the shot hole by 30m. The shot hole was backfilled and a seismic timer was used to detonate the explosives and simultaneously trigger the seismograph. A 24 channel Geometrics Geode data logger was used with a 0.25ms sampling interval and total record length of 4096ms. Data were processed in REFLEX, to pick ice-water and water-seabed reflectors. Any sites in which only one clear reflector could be distinguished were not included in the final dataset.
A detailed methodology is given in the referenced publication.
Data collection:
24 Channel Geometrics geode data logger used.
Processed with Reflexw 7.2.3 software.
Analysed in Matlab 2017a.
Data quality:
Water column thickness and Ice thickness errors, arising from uncertainty in seismic velocities, temperature and reflector shape, are expected to be less than 10m. A detailed description of the expected errors can be found in the referenced publication.
