Basal Melt Rate Beneath Pine Island Ice Shelf (2014)
The basal melt rate at a single location beneath Pine Island Ice Shelf was observed using an autonomous phase-sensitive radio echo-sounder (ApRES) during 2014. The ApRES was deployed approximately 10 km from the ice shelf front where the ice was 492 m thick and the ice shelf draft was approximately 422 m. The ApRES was deployed as part of the NERC Ice Sheet Stability Program (iStar).
Funding was provided by the NERC Ice Sheet Stability Research Program.

Methodology:
The data was processed following Nicholls et al. (2015). Formally, the raw Lagrangian ice shelf thinning rate at two-hourly resolution was derived from the time-derivative of the distance between the ApRES antennas and the ice shelf base, and includes the basal melt rate signal as well as a component of ice-column vertical strain rate resulting from ice flow and snow compaction. To remove the component of ice-column vertical strain rate due to tidal variations, the raw thinning rate was low-pass filtered using a cut-off at 48 hours. At frequencies lower than this, variability in the strain rate component is small compared with the basal melt rate and varies on a much longer timescale than those of interest here.
Data collection:
Instrumentation: Autonomous phase-sensitive radio echo-sounder
Data quality:
The basal melt rate has an accuracy of ±0.2 m/yr and has been fully quality controlled. There are no missing values.
Resolution: Two hourly resolution with a 48-hour low pass filter applied.
