Processed airborne radio-echo sounding data from the GRADES-IMAGE survey covering the Evans and Rutford Ice Streams, and ice rises in the Ronne Ice Shelf, West Antarctica (2006/2007)

An airborne radar survey was flown as part of the GRADES-IMAGE project funded by BAS over the Antarctic Peninsula, Ellsworth Mountains and Filchner-Ronne Ice Shelf (also including the Evans Ice stream and Carson Inlet) mainly to image englacial layers and bedrock topography during the 2006/07 field season. Operating from temporary field camps at Sky Blu, Partiot Hills and out of RABID depot (Rutford Ice Stream), we collected ~27,550 km of airborne radio-echo sounding data over 100 hours of surveying. Our aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, and an ice-sounding radar system (PASIN). Note that there was no gravimetric element to this survey. We present here the full radar dataset consisting of the deep-sounding chirp and shallow-sounding pulse-acquired data in their processed form, as well as the navigational information of each trace, the surface and bed elevation picks, ice thickness, and calculated absolute surface and bed elevations. This dataset comes primarily in the form of NetCDF and georeferenced SEGY files. To interactively engage with this newly-published dataset, we also created segmented quicklook PDF files of the radar data.
