Summary
Abstract:
The dataset comprises ApRES (Autonomous phase-sensitive Radio Echo Sounder) time series from a site (S0715) located on the western Ronne Ice Shelf. The instrument was deployed in early 2016 as part of the Filchner Ice Shelf System (FISS) project. The aim was to provide time series of basal melt rates and the vertical strain rate.
Funding:
The data were acquired under funding from NERC - the Ice shelves in a warming world: Filchner Ice Shelf System, Antarctica (FISS) grant NE/L013770/1
Keywords:
ApRES, Basal melt rate, Ice Shelf, Ronne Ice Shelf, Vertical strain rate

Additional Information
| Quality: | The time series are raw, unprocessed data. The dataset consists of two intervals. The first lasted about 6 months. The instrument was reset during the 2016-17 field season, and it then ran for another 6 months. | |
|---|---|---|
| Lineage/Methodology: | The data were collected using standard ApRES methodology with instrument configuration described in data headers. The radar bandwidth was 200 MHz, centred on 300 MHz with a 1-second chirp length at a nominal power of 20 dBm. Bursts of 30 chirps were collected at 2-hourly intervals (nominal). The acquired ApRES DAT files were losslessly converted to netCDF files using apres_to_nc from the bas-apres Python package. | |
