Abstract:
In 2014 polarimetric phase sensitive radar data were collected at Korff Ice Rise, West Antarctica, with the aim of studying fabric within the ice column and ice bed properties. Data were collected at sites within 700m of one another along the axis of the ice divide. The radar data were collected by rotating the antenna through 180 deg to allow reconstruction of the azimuthal variation in power and phase.
This study is part of the British Antarctic Survey programme Polar Science for Planet Earth. All data were collected with the support of the British Antarctic Survey. The ApRES fieldwork were funded by Natural Environmental Research Council grant NE/J008087/1, led by Richard Hindmarsh.

| Quality: | Antenna pair is rotated simultaneously through 15° intervals anti-clockwise from 0 to 180° | |
| Lineage: | The antenna pair at 7m separation is rotated simultaneously through 15° intervals anti-clockwise from 0 to 180° (0° in the experiment frame of reference is 149° true bearing) at a single site on the ice divide. | |
